We all know how important it is to supply our customers with a BMD machine that meets their needs.
The BMD Team put some information together to help you in select the best machine to do their job most efficiently. Hover with the mouse over the different sections that are colored red and see extra information on why this is essential and how it can benefit you. The more information you have from your client, the better outcome you can expect. Making the determination which machine fits best in each situation, what enzyme mix is most suitable, and what add-ons may be needed, provides the client the professionalism that will make your business grow.
You also have the option to send us data and other information about your potential client so that we can look at it together to make final decisions on your recommendations for the right BMD size(s), and enzyme mix for your client.

Predominant food waste at the facility

Knowing the predominant kind of food waste of the location is the first essential part of determining the right BMD machine.
Check out the different food waste types and see how they affect how many pounds (or kilos) of food waste the BMD can handle.

This is the food waste for an average restaurant. Most of the food waste is cooked and there is usually less than 10% fiber products in the waste. This is the easiest food waste for the BMD. Most of this type of waste is gone within 5-6 hours,,,,,,,,,so it is possible for the BMD to digest more than the suggested food waste amount per machine. Of course, the number of times filling the machine per day will also be a factor to consider. (see the “Usage of the machine during the day”) for more information


When this type of food waste is predominant, we see that there is a slow buildup of material in the machine.
10-20% of the total input of this food waste takes several days before it becomes fully digested. Keep this in mind when determining the sizing of a BMD.
When a client has 50-60 kilos a day with a large number of Raw Vegetables, fruit, and Shellfish, it will be best to advise a BMD-100. This way we are sure that the build-up of slowly compostable material is not clogging up the machine after several weeks.
A helpful tip for your client—if there is a budget limitation—is the option to cut the raw vegetables and fruits into smaller pieces before putting them into the BMD Machine. Smaller pieces will help the digestion process a lot. (preferably to make the pieces smaller than 5 cm) The enzymes can attack small pieces much better and faster.

What is true for the raw vegetables is also true for the high fiber food waste, but to a larger extent. Raw Lettuce, cauliflower, celery, carrots, beets, broccoli, and other high-fiber product will take days, or even weeks to digest.
When the predominate food waste is high fibers the digestion process takes longer. Add to that factor, is the frequency that food waste is added to the BMD.and when filled every day of the week a buildup will happen. Depending on the % of fiber waste in the waste stream it can be that the client needs a machine that is 4-5 times bigger than according to the total waste amount per day.

When there is still cooked and staple food in the high fiber waste, it helps with the digestion process. The extra moisture in the mix, causes the enzymes to travel to the fiber waste more easily.
It may be necessary to add a shredder unit into the facility – The picture next to this is an explanation of the buildup of the fiber material when filling the BMD machine with 50 kilos of fiber food waste. As you can see, the buildup is significant and you need to recommend a larger capacity BMD to get rid of the fiber food waste. We are working on special enzyme mixes that can handle fiber food waste more quickly. We will keep you posted as we learn more about the new enzyme formulations.
Another option could be to recommend two BMD machines so the waste can be separated into two machines.
Be sure to ask for our support in deciding what machine is needed for the specific client, when there is only fiber waste. A raw vegetable production facility is an example of that. An enzyme mix, special for that waste stream, may be required.

Up to this point, we (like all other aerobic digester companies) do not have the right enzyme mix to support bio-plastics in our BMD machine. It is possible to add sugarcane pulp material. Sugar cane pulp products are in the category of high fiber products and will build up in the machine.
PLA/ bio-plastic kind of materials is not digesting in our BMD machines so far. Best to not promote a BMD machine for this combination of waste at this time. When we find the solution for this waste stream, you will be the first to be introduced to our BMD+ line of products.

This kind of waste stream needs special attention and might even need a specially built machine. Some of the mono-streams are beer waste, ice cream waste, coffee waste and tea waste. When conducting the research and development for solutions to these waste streams, BMD will be seeking operational partners who need our kind of a solution. We are already working on different kinds of BMD machines and when we have a solution for mono stream waste you will know about it.

Usage machine during the day

The second part that is a factor in how much food waste our BMD machines can handle, is the number of times the machine will be filled during the working day. We see 3 different categories in filling the BMD machine.

Filling the BMD machine once a day with the suggested food waste kilos is possible with all of our BMD Machines. All machines have the bin capacity to hold the minimum waste capacity when filled once. This makes it possible for the facility to collect the food waste during the day and only have one action to do at the end of the day.
When the facility is filling the machine once a day, that can give you an up sale opportunity. The BMD with the attached loader is ideal for a once-a-day filling. The client can keep using their green bins – and keep their workflow the same as before. The green bin is simply attached to the BMD, and the loading is complete. For the BMD-100,200,300 and 500 the loader is optional. The sizes BMD-1000 and larger, come as standard with a loader.

Important info:
When filling the BMD once a day, there is not a lot of wiggle room between the minimum kilos per day the machine can handle. So, you have to be sure that the volume of the BMD is big enough to handle the existing food waste at the facility. Adding more than the suggested food waste can damage the machine and consistent overloading eliminates the warranty on it.
We see that some competitors in the market present their machines as an (example) 150 kilos per day machine – suggesting that their machine can handle 150 kilos a day. But when looking into the details this machine can only handle 150kilos /24 hours. Meaning 7 kilos per hour. It’s important to educate the client on this and inform them about the benefits of purchasing the BMD.

When a facility uses this way of filling the BMD there is a possibility that the BMD can handle more food waste then the suggested kilos. (especially when it is cooked food waste.) With this waste stream we see a decrease in weight of 40-50% in the first 5-6 hours. This decrease is not due to the digestion process but purely the moisture of the food waste exiting the machine.
How much food waste can the added more during the day,is difficult to say. It has to do with – kind of waste, amount of meal moment, and the opening hours of the day.

We suggest that you be cautioned in advising a BMD lower than the amount of food waste on location. When using the “filling after every meal moment”, caution needs to be taken when the amount of food waste on location is more than 40% of the machine’s suggested waste kilos. It all depends on the kind of predominant food waste.

Filling the BMD continuously—in the kitchen—is the most hygenic and efficient method of all. This all depends on the “set-up” in the kitchen for space and convenience to taking care of food waste. Using the BMD like this will give the most chance to add more food waste during the day than the minimum suggested amount of the machine. All employees who use the BMD will need to be briefed on what can go into the BMD and what cannot go in. As a reseller, you will be expected to conduct a “training session” at the location prior to its operation.

Check out the facility together with the client and see if there is a space in the facility where the BMD machine can be placed so it fits in the “fill it when you have waste” idea.
This means that the BMD machine must be located close, and preferably in the area, where the food waste is created. The further away the BMD stands from the location where the food waste is created the more efforts must be made to fill the machine.
We see from the past that when this is the case in a location they will turn to “after every meal’ or “once a day” filling of the machine.

The BMD with loader function

You will see that a lot of facilities will prefer to fill the BMD once a day. This because, it saves employee costs, they already work this way, and resist change. This method comes into play when there are several locations at the facility that will be using the same BMD machine.
Food waste will be collected in buckets or green bins and fill in the BMD at the end of the day. With the BMD the facility does not need to change the procedures they have. They can still use the green bins for collecting the food waste.
All of our big machines (the BMD-1000 and up, come with a green bin loader). But also the BMD- 100, 200, 300 and 500 can be equipped with a special loader. This BMD with a loader is around 20-25% higher in price. But it will give the client more flexibility. The BMD with a loader can also be used as the normal BMD and manually fill with food waste.

Estimating the amount of food waste per facility

There may be cases, where the client is not able to give detailed food waste information of his/her facility. Then you can use the estimates below. Hover over the different pictures of the facilities and see how to make an estimated calculation of the amount of food waste per type of facility.
Keep in mind that these are estimations and actual amounts of food waste per facility/country the numbers can vary a lot. So, try and look for other clues to come up with a more accurate number of food waste.

nursing homes are ideal places for a food composter

Future changes expected at the facility

When we search for all the information to recommend the correct BMD for the facility, it is always a good idea to raise the topic of future growth and/or expansion. Buying a BMD machine is for a the long term—even ten years or more.

Are they going to expand, or downsize? Will they add another food moment – like breakfast? Are they going to extend or limit the opening hours? Will they have a potential new client that will increase the production?
All future changes that can impact the amount of food waste per day – and therefore the BMD they need.

Calculating the amount of food waste

Now that you know all the different parts of how to decide which BMD machine will work best for your client. It’s time to fill out your checklist with all the information you have about the client. We advise you to do this together with the client where possible. The involvement of the client is higher when doing this together and you avoid having “I did not know” or “that’s not what I told you” situations.

It’s extra safety, if there should be troubles during the use of the machine. When the client helps fill out the form, you, as a re-seller, may assume that the information is correct. When in real life, food waste is different and it’s much more than the machine can handle, or different in the kind of food waste then put on the form. It will not be a “blaming and pointing fingers argument” – it’s now only a “how can we solve it” subject.
Below an example of a document you can fill in with the client. – Adding this filled document with the quote/invoice can be a good idea.

The longer a facility is open - the more opportunity they have to throw in food waste during the day. When a facility is open for a short amount of hours during the day - it is unlikely that the BMD can handle more food waste than the "minimum" amount. (example; A BMD-50 machine can handle between the 50 up to 99 kilo's per day. depending on the times it is filled and the kind of food waste.) 




35 kilos











If you have any doubts if the machine can handle the amount of food waste it needs to handle during the week. A day that the facility is closed can bring some extra space in what the machine can handle. With no food waste going into the machine there will be more buffer for the coming days. 
Keep in mind that it can be that the facility is open 7 days during the high season. then we can not use this buffer to present a smaller machine. 

Use the highest food waste per day when: The facility only fills the BMD once a day or has high % fiber raw vegetables.








The different eating moments during the day, can be important to decide what BMD machine the client needs. If they will throw away the food waste after every eating moment (breakfast - lunch - dinner.) The BMD machine can handle more waste per day when they have 3 eat moments than when they have 2 moments. (specially when it is cooked food)

Average per day



Normally you advise a BMD machine on the average food waste per day. This is the saves and easiest way. In this case a BMD-30 or BMD-50.
BUT --- when the "highest waste per day" exceeds the average a lot you need to use the highest food waste amount per day. Especially when the facility only throws in the food waste ones a day. or the facility has a lot of fiber vegetable food waste.  

40 kilos

highest waste

50 kilos



Use the highest food waste per day when: The facility only fills the BMD once a day.
Keep in mind that you use the amount of food waste in the HIGH SEASON period.

Extra info: During the high season, the location is open 7 days a week. According to the chef, the amount of food waste does not vary a lot between the low and high seasons. estimated food waste on tuesdays 15 kilos

There are no big plans for the future to change the opening hours, kind of food waste, and amount of seating options per day. 
The client is using compostable products for the catering part of the business. And for the future is interesting when the machine can handle compostable packaging/bio-plastic and food waste. 

Service and payment options

Different service options

At BMD we want to supply our clients with different service options. With the below services packages we think there is a service package for every client.

All of our BMD machines have a warranty on electronics of one year and a 3 year warranty on mechanical parts.

The 3-year ALL-IN service is ideal to combine with a 3-year lease contract. This way the total costs of the machine, enzymes, and Bio-Chips can be paid monthly. And the clients are sure of the service during the full 3 years of the lease.
What is including the 3 year ALL IN service deal?
• 3-year full warranty – also on electronics
• 3-year supply of enzymes
• after 2,5 year change of Bio-Chips
• 5% discount on enzymes and Bio-Chips

The 5-year ALL-IN service is ideal to combine with a 5-year lease contract. This way the total costs of the machine, enzymes, and Bio-Chips can be paid monthly. And the clients are sure of the service during the full 5 years of the lease.
What is including the 5-year ALL IN service deal?
• 5-year full warranty – also on electronics
• 5-year supply of enzymes
• after 2,5 year change of Bio-Chips
• At 5 years change of Bio-Chips
• 10% discount on enzymes and Bio-Chips
For cleaning, emptying, and refilling the BMD machine with new Bio-Chips and enzymes every 2,5 years the reseller gets a fee from BMD for this service.
These contact moments with the client is also a good option to look for sales add-ons. Like a shredder, other BMDs for the second location, and checking for leads in the area.

Different payment options

Besides the normal invoice option there are also 3 and 5 year lease to own packages you can provide your clients. This makes owning a BMD machine even more interesting for a facility. No high costs for buying the BMD machine, low monthly costs – can make the step to a BMD machine easier.

For most of the EU and the USA, we have partners available that can provide lease-to-own solutions.
The client will have direct contact with the lease company. They will contact the client and check the possibilities for a lease solution.
The add-on price for a 3 years lease is on average 10% of the sales price. The exact lease price will be communicated by the lease company.
You can download an application form for the European lease company at the download page.
A 3-year lease to own is ideal to combine with a 3-year ALL-IN service contract. This makes it possible to pay for the enzymes and Bio-Chips on a monthly basis. It also gives a discount of 5% on the enzymes and Bio-Chips.

For most of the EU and the USA, we have partners available that can provide lease-to-own solutions.
The client will have direct contact with the lease company. They will contact the client and check the possibilities for a lease solution.

Turing food waste into grey water. Showing a 48-hour cycle of how our BMD machine turns food waste into grey water.
Most of the food waste is gone within 24 hours. The rest digests in the 24 hours after that. Depending on the kind of food waste of the location this process can go quicker or slower. Some high-fiber food waste takes several days/weeks to digest.
Contact us for more information.

Within 24/48 hours our food waste machine will digest food waste into grey water. no hassle, no solid waste stream, easy to operate and maintain.

Food waste from an Ala carte restaurant was digested in our BMD food waste digester. Digests food waste into grey water in 24/48 hours.

Frequent asked questions

All the digested food waste, grease, food juices and water in the food waste together will become greywater. The grey water changes depending on the food waste that is going into the BMD.

Between 20-27C (70-80F) It depends on the temperature inside the machine – and the input of water temperature, but the grey water temperature is always lower than the temperature. inside the BMD.

The grey water goes into the sewage system when connected. Nothing needs to be done with it from the point of the user/operator. It’s an ongoing process of grey water going into the sewage drain.

The machine is almost odorless.
If an odor is detected, it may be that the amount of water in the BMD is too low, the temperature in the machine is too high, or the enzyme mix needs replenishing.

NO, all of the enzyme and biochip additions to the food waste are environmentally friendly. They rely on environmentally friendly microbes and water. Microorganisms are extremely common and can be found all around us. There is a Material Safety Data Sheet that shows how to treat the enzymes in a completely safe manner.

BioChips are hard plastic pieces that stay inside the machine all the time. The enzymes/bacteria live inside the biochips. The Biochips also help make the food waste smaller so the enzymes can eat them easily and the digestion process goes faster. In 2023, we plan to begin to make these biochips from plant-based plastic.
The Biochips stay in the machine for 2-3 years. During that time, it is unlikely that there would be a need to add additional BioChips. Therefore, the weight of the biochips will not change very much during their lifetime of service.

Yes, we can send you different lab tests from the different kinds of food waste that we have done in our laboratories.

The data sheet on our website (“our machines”) shows how many liters of water comes out of the different machines.

It is possible to store it and use it as fertilizer, but it depends on what kind of food waste you put into the machine – and how useful it could be for fertilizing.

No. You add waste food at any time—day or night—24/7. The machine is constantly digesting the food-waste.

At this moment 1 Biochips – we are working on a plant-based/PLA biochip but that will be not sooner than end of 2023. We have one enzyme mix for general food waste. And are working on different enzymes mixes for more difficult to digest food waste.
We believe that there is always room for improvements, and are continually testing new mono stream enzyme mixes. Ice cream waste – brewery waste – PLA/compostable packaging – fiber products – cotton – fibers are all applications that we are working with. If a reseller has a client with a specific waste stream that has not been possible for aerobic digestion, we can see utilize some of our experimental enzyme mixes to find a solution.

The biochips are made of fossil plastic at this moment. So yes they are wasted after 2-3 years and can be put into the recycle stream available in your country. A better Biochip is on the way

We have not heard of any country where a liquid food digester is banned. There are ways to change the amount of waste per liter of water coming out of the machine. So when we exceed the limit for a country we can look at solutions. Some countries require a special grease trap, but most locations that handle food waste – like restaurants and schools – already have a grease trap in place.

 It’s best to start testing at your specific location to see what you can do with the grey water.

There is no CH4 released during the process.– A small amount of CO2 is coming into the air. That is normal with aerobic digestion. The amount of carbon dioxide released from the food waste disposer is much smaller than that released when incinerating and burying it in the landfill. It emits a very small quantity of carbon dioxide—about the same as when people breathe.
It’s important that we keep food waste out of landfills. Every 40 kilos of food waste in our landfills sends 4 kilos of methane into the atmosphere. Over 20 years, methane has 86 times the global warming effect than that of carbon dioxide.

There is no research done on reusing the existing Biochips after the 2-3 years of use. When we are ready with our PLA Biochips they can be safely burned for energy, or taken to an industrial composter.

The Biochips are always the same whatever waste stream there is.
We have an enzyme mix that can handle most of the food waste types. So, these will not have to change. This is more a process before installation. At that point, we decide what enzyme mix will work best for the client. We are working on different enzyme mixes for specific mono waste streams and the future PLA/compostable packaging waste stream.

It’s an ongoing process. You can dump in some kilos in the morning – then during lunch again and before closing the location, the rest. You may also dump in the food waste at one time of the day – it does not matter. When there is food waste, it can be added into the machine.
The enzymes will stay alive for some days when they don’t have any food at all. So as long as there is food waste into the machine they will do the work.

When a product stays inside the machine it is best to take it out and throw it in another waste stream. Bones can be an issue when they are large – they will not go away and could damage the inside of the machine. These bigger bones need to be removed. In most countries, bones are not seen as organic waste – so can be thrown into the grey bin.
In the smaller machine you can hand pick the bones and other solid matter out of the machine. With the larger machines you might need a sieve or garbage grabber.

No shredder is needed for the food waste. Certain large fiber kinds of products – like celery , pineapple, and the outside of the cauliflower, needs to be cut is smaller pieces.
It might be that a specific mono- stream waste must be shredded, but if that’s the case, a special unit will be provided.

No – everything together is fine. Some take longer to digest then others but because it’s an ongoing process, you can just mix everything.

If we know there is a specific waste stream, we can look at what will be the best cycle. More turning – less standby time – more water – less water – higher temperature in the machine. The turning of the blades – standby time – water in – water out – temperature inside the machine can all be changed. Depending on the need of the individual location and their specific waste stream. But for a normal food waste stream we can just use the standard setting for 2 x 5 minutes turning and 10 minutes standby and 25-30C temp. The existing water pressure may make a slight difference in this equation.

In the bottom of the chamber is a sieve. When sand is coming into the machine it will dissolve in water or when it’s small enough it will go to the sieve and into the greywater – sewage. Large amounts of sand can disturb the process and need to be avoided.

Best is if the food waste is not exceeding the height of the blades in the machine. This means that there is always free space between the end of the blades and the top of the machine.

Bio-plastic digestion is currently not being digested, as far as we know. We are working on to get the right enzyme mix. Big bones, hard nuts, and pits of fruit are difficult for the machine.

There are load cells mounted on each corner of the digester. These weigh the total weight of the digester. On installation, the software calibrates itself so it knows the empty weight. From there, the software knows how much is in the food composter and how much is added each time.

Large amount of fat and grease will be problematic. And because fat/grease turns into liquid quickly, it will go to the sieve out of the machine – and not always be dissolved. That’s why with large amount of fat food waste, a grease trap is already installed in the restaurant from the beginning of the business.
We are working on enzyme mixes to handle the grease more efficiently.

Yes you can stop the machine – it’s not recommended but it is possible. The enzymes need food to stay alive so when there is no food they will die in several days. if you stop the machine and there is food waste inside, the food waste will rot instead of digest – and that will create odors.
What you can do, when the restaurant may close for a week – you can put some hard fibers food waste into the machine and shut down the machine. The change that these hard fiber vegetables will rot is reduced, and it gives you the best change of keeping the enzymes alive.
But, in the case of seasonal restaurants that close for a long time, this is not an option. The only thing to do in that case, is cleanout the machine after the season and start the next year with a new fresh batch of enzymes.

The change is that with a food production facility, there is often a waste stream of only one product. Together with other food waste this material will go away in the BMD machine.
This kind of specific client might need to conduct a pre-test on a small scale first – to make 100% sure we have the best enzyme mix and settings. Every mono stream of waste needs special attention from us.

The water input and output stream are standard at the beginning of installation and will stay the same – regardless of how much food waste is added into the machine. These settings depend on the kind of food waste that goes into the machine. You set the sprays on 5-10-20 seconds per cycle. The water in and output can be changed when the machine is running but will probably not be necessary.

If the capacity of the machine is 50 kilos (like the BMD-50) that means that it can handle 50 kilos of food waste per day. The enzymes and Biochips are not included in this calculation.
It can be that some specific waste is light and creates a lot of volumes. Then you may wish to choose a larger machine.

Best to make sure the client will arrange a water in and output before the installation. And when that’s in place, it will take 30 – 90 minutes to make the machine ready. (depending on the size of the machine)
It is just connecting to the water /sewage – calibrate the scale – add enzymes – press start. That’s basically the process.

We have machines that we use for B2B fairs – that we might be able to install at a potential client location. We have for example a BMD-50 that we can use for testing at a location. The client will need to pay for the test machine and when he buys a large BMD the costs are deducted from the sales price.
The technique of the machine is not new. It has existed for more than 20 years. The technique works. Thousands of different liquid food digesters are installed all over the world. So, when a client has a normal BMD food waste stream we are completely confident that it will work. When a client has a specific food waste stream, other than food waste, we will make sure that we know it will work, before talking to them about selling a machine.
Most clients, when seeing the machine in action, find it hard to believe—because it is so simple. You dump food waste into the machine, and within hours, grey water comes out.


The plan is to set up a warehouse – training location – showroom – office in the Netherlands and the USA in 2023. There will be videos and manuals to make everything clear for the end-user. The machine is so easy to install, use and repair, that electrician repair/ wash machine repair person can do it. And he/she will have the right drawings/information to be successful.

We expect that the BMD-30 -50 -100 – 200 Will be the most popular machines. But it all depends on what your target market is. It can be that you focus on the yachts/boats in Costa Rica and then a BMD-10 and BMD-30 could be the best-selling machine in your area.

-From all competitors, price is one of the benefits.
-The different enzyme mixes that we are working on.
-Our machines are made at a factory with over 15 years of experience
-We have 12 different sizes – more sizes then all competitors. So there is always a machine that fits the client.
-The quality of re-sellers that we have.
-Our companies’ service to the re-sellers


The machine will get a cloud function – that is planned in 2023. So the owner can see how the machine functions. The mechanical system is simple – our factory has a long reputation for making reliable machines that almost never break down. Of course, if the machines are abused by overloading the machine constantly, one can expect trouble.

There is a light humming sound that the machine makes – sort of a quiet washing machine.

At this moment our factory has the spare parts on stock , but we will store them in the Netherlands and the USA when the warehouses are ready. There will be a spare parts cost-list to be used by our re-sellers, and our offices will assist in supplying the needed spare parts.

Warranty: 1 year on electronic parts and 3 years on mechanical parts – an extended warranty of 5 years can be added for extra costs of 5% added to the retail price. But this is only possible when choosing the 5-year ALL IN option. 


We want the BMD to be a solution to the food waste problems around the world. Whatever needs to be done to get that job done—-is our joint efforts together.


There are options to supply a client with not only the BMD machine and the first 6 months of enzymes. But with a full package of 5 years Warranty, 5 years of enzymes and 5 years of BioChips.
Beside the normal BMD we also have, for the BMD-100, 200- 300 and 500, the option to make it a BMD with Loader. This machine can carry a 120 liter green bin and throw the food waste, what is in the green bin, directly into the machine.
In the future, when we have the right enzyme mix for bio-plastic/compostable packaging, we will supply our resellers with a list of different compostable packaging products that will digest in our machine. That can be ordered from BMD.

-Keep the machine clean
-Throw in the food waste
-Check every several days if there is something in the machine that does not belong there and get it out. Like fossil plastic – metal, glass
-Adding enzymes in the machine when needed (normally every 6 months)

There is no automatic cleaning system in the BMD machine. There is not a lot of cleaning to do in the machine. The water and enzymes/bateria in the machine clean it for the most part. When you fill up the machine too high the food waste will get stuck between the water input piping. That needs to be removed.
Every several weeks it can be smart to look if there is stuff tangled around the turning parts of the blades. But it all depends on what kind of waste is put into the machine.

We have test machines – depending on where you are located, it is possible to visit our test facility. In 2023 we are setting up our own test and showroom facility in the Netherlands.
We can also search for an existing client that has a BMD installed close by in an area/country and plan a visit if the client is willing to support this…and we are pretty sure that they will.

All machines need to be ordered for production. Production time is 6 weeks and from – another 4-6 weeks for shipment. In 2023, when we have stock in the Netherlands and the USA we can deliver more quickly (within 1-2 weeks). Large machines of BMD-1000 and up will not be put on stock in our warehouse.

Payment terms are 60% with your purchase order for one container-load of machines before production – 40% 3 days before shipping the machines.

We become business partners. We ask for honesty and hard work, and the shared vision of seeing the BMD as part of the environmental solution to the serious work of keeping our Earth intact for ourselves and our children and grandchildren.
