3-10-2021: Wood pellets, which are biofuel particles made of compressed sawdust and chipped wood from logs, are the Netherlands’ most important source of biomass for energy production. Since 2018, imports have doubled in volume each year fuelled by biomass energy production subsidies under the Sustainable Energy Production (SDE+) scheme. To ensure that biomass is produced sustainably, a normative framework with principles and criteria was set up. Energy companies that want to receive subsidies for co-firing wood pellets must show that they have been produced in compliance with all the criteria.
