Increase your secondary resource use

Are you ready for 2030?

Over 400 companies have signed the Dutch Resources Agreement. This agreement specifies that in 2030 50% of all resources in the Dutch economy need to be non-virgin. In 2050 a 100% of these resources need to be secondary.

The EME provides a reliable source for buying and selling of secondary materials. By using our marketplace your R&D time for sourcing secondary resources can be reduced by as much as 85%.

Turn your waste into a revenue stream

At the moment, waste processing costs represent on average 5% of the total revenue of a company. With the EME we help you turn your waste into wealth.

By offering your materials, components, and products on the marketplace you will get paid for them instead of paying to get rid of them. We could reduce your waste processing cost by as much as 150%.

Join our platform and receive data that enables you to make different strategic decisions and potentially unlock even more value for your company.

Achieve your sustainability goals faster

Did your company also set ambitious sustainability goals? Are you looking for tools to achieve them? Maybe even faster than planned? With the EME you can source and sell your excess materials. Fast, for transparent market prices and in a secured manner. We actively facilitate the making of high-value reuse matches of materials, components and products. Moreover, we calculate the environmental and social impact your transaction has. This proces is automated on our platform, so you can immediately include this in your annual report.

What we offer

How we work

Find out how we turn your waste into wealth. To make successful matches we use a holistic and systemic process. The following four tools are instrumental to this process:

1. Resources Passport

The resources passport helps saving material, component and product data in a structured manner by giving materials an identity.

2. Tracking & Tracing

With tracking and tracing identifiers like bar- & QR codes and chips we effectively couple materials to the resources passports and follow them through their life cycles

3. Valuation

We calculate the financial value, and the environmental and societal impact of the matches we identify.

4. Matchmaking platform

We facilitate the matchmaking of material streams to find the highest-value reuse of materials and products.

Results of the pilot

Unlocked potential for 18 streams:
car rides from Amsterdam to Milan in carbon emissions reduction

Tulip flower heads

The Netherlands is famous for its tulips. After flowering the tulip heads are cut off and wasted. Growers sometimes even pay to get rid of them. Yet, they are a valuable resource in other sectors. For example, they could be converted into pigments for paint. 800kg of pigment can be retrieved from from one hectare of land. This leads to a total market in the Netherlands of all tulip field of €1,5 trillion euros in pigments.


Water company Vitens regularly received phone calls of users that their water was oddly colored. This was due to harmless (actually healthy) organic compounds. Yet color was more important to their customers, so Vitens filtered out the organic compounds and send this excess material stream to an incinerator. Costs: half a million annually, and a waste of valuable resources. They decided they could optimize this process. Within two years they refined their purification installation and now sell the salts and organic compounds with a big profit to various companies. They also sell the technology behind the new purification installation.

Fruitleather Rotterdam

Each year we throw away 1.3 billion tons of food. Currently 30% of the world's farmland is used to produce food that will be wasted. Moreover 10% of all greenhouse gasses in rich countries is emitted by producing food that will never be eaten. The design duo Fruitleather Rotterdam transforms fruit into sustainable leather like material strong enough to be used in shoes, bags and other products.

Closing the Loop

Closing the Loop buys your redundant IT hardware - and gives it a second life. Data-secure, easy and uniquely sustainable. They also collect and buy end-of-life mobile phones in emerging markets. This social business leads to sustainable jobs, waste reduction and more recycling. With the help of their strategic partners, over 95% of the metals can be retrieved from the already collected 1 million scrap mobile phones.

Our vision is to reinstate waste for the valuable resource that it is.
In the process we want the word ‘waste’ to be removed from the dictionary.

Frequently asked questions

Looking for more information? See our FAQ below or send us a message.

Any material, component or product can be exchanged on the EME. Waste in one sector usually remains waste in that sector and the possibilities for high value reuse are low. Think about coffee leftovers. This remains waste in the restaurant sector. Optimization by for example drying and burning the leftovers at the restaurant is not always the most optimal solution. The leftovers are a valuable resource for mushroom growers. In the pilot we have circular economy A-players and frontrunners as participants. These companies, like yours, very often already have an insight into their material streams. Together we will look for the most optimal reuse opportunities for any type of the material streams between sectors and industries to truly create a circular economy.

Yes, Blockchain Technology will ensure the safe exchange of proprietary data. Companies will remain the owner of their own sensitive data while materials will be traced anonymously. The blockchain also ensures non-corruptibility and traceability of supply chains and will help prevent frauds.

Our fuzzy matching tool connects available material streams with relevant data of thousands of scientific papers and patents. This allows us to quickly identify alternative uses for each material. Eventually an AI toolkit will be developed to initially aid and ultimately automate the matchmaking between supply and demand, and between materials and their highest value reuse opportunity.

We are continuously improving our software. At the moment it is not possible to automatically link your database to ours and upload your data like that. However, do not hesitate to contact us and tell us your needs. We are working hard on making this possible.

With a fully functioning EME the logistics will just be a click away. Until that time and during the pilot logistics we will investigate how to optimise the logistics.

Our partner Stibbe helps us and your company to investigate and overcome the legal barriers for the high value and appropriate exchange of excess materials. We are making an inventory of the most common barriers and will publish those in a report.
