> Wet digestion

An extremely sustainable process

We have access to a unique wet digestion plant in the western part of Amsterdam's port. This plant converts approximately 120,000 tons of liquid organic waste into heat and energy which is used to power nearly 10,000 households each year. We also clean our process water and waste water from a number of large industrial suppliers using our water purification system.

This is how wet digestion works

The liquid, energy-rich organic waste materials supplied are placed in a sealed reactor where they separate into water, fats, starches, sugar, proteins and fiber during wet digestion (this process is also known as hydrolysis). These 'intermediates' are then converted into lower fatty acids by acid forming microorganisms and are then broken down into acetic acid, hydrogen gas and CO2. Methane forming microorganisms then convert the gas mixture into methane and CO2. This mix is also known as biogas. The digestate left over from the wet digestion process is dried using our own sediment line. It is then converted into Orgapower Powermix (our brand of extremely well-performing, NPK rich soil enhancers).
