Site

Our Biocel plant in the Netherlands is unique. This plant can digest a huge variety of different types of organic waste without much preparation or final processing. This is achieved using a special 'dry' anaerobic digestion facility thatyields amazing (environmental) results.

World-class technology that just keeps performing

Our Biocel digestion and composting facility in Lelystad isn't just extremely efficient, it has also run non-stop for nearly 20 years. There is a reason why our customers (a collaboration between the municipalities in Flevoland) have extended the contract for processing of organic waste in the province and we are meeting with lots of potential customers from abroad interested in our technology.

How it works

The volume and make-up of organic waste can vary during the course of the year with peak periods during the spring (leaf and yard waste) and the fall (leaves and cuttings). The use of standard digestion facilitys causes a number of problems. However our Biocel plant is problem-free: the organic waste is fermented in special air-tight reactors following minimal preparation work. The biomethane gas which is released during this process is used to generate energy and heat. This is how we produce nearly 4 million kWh of electricity per year. This is enough to power 1500 houses with green electricity. We use some of this heat to regulate the temperature in the biocel. The anaerobic digestion process stops after 21 to 28 days. The remaining product - the digestate -, fresh organic waste and the innoculum are converted into compost in composting tunnels over the course of 5 - 10 days.

Depackaging line

Our Biocel facility in Lelystad also houses our new depackaging line. This line is used to depack products that have passed their sell-by date. The packaging is removed from these products and the waste is broken down to a pumpable 'supermarket mix' which is then converted into biogas and organic fertilizers via wet anaerobic digestion at Orgaworld's Greenmills facility. This 'supermarket mix' can also be supplied to third parties.

Extremely low odor and particle emissions

One of the things that makes this location unique is the fact that there are hardly any odors released. This is not a problem as the building and the facilitys are kept under negative pressure and all the air is thoroughly cleaned before it is emitted in to the surrounding area.
