Vegetables, Garden and Fruit (VGF) waste at the basis of 3 sustainable products

On 16 April 2015 Indaver officially opened its ultra-modern VGF digester Bio Power in Alphen aan den Rijn. The innovative digester is the only one in South Holland that can both digest and compost VGF waste, green waste and biowaste from the food industry; Indaver is emphatically opting for quality – i.e. high-value recycling – over quantity.

VGF composter Alphen aan den Rijn: interventions to further improve quality

Bio Power Alphen is Indaver’s cutting-edge VGF digester. When developing this facility, thankfully we were able to make use of our previous knowledge from EcoFuels. Indaver recovers three valuable products: compost, green gas and liquid CO2, from the vegetable, garden and fruit (VGF) waste produced by municipalities in the wider area, thus closing the materials loop.

Growing production

Operational since June 2014, Bio Power Alphen immediately met the highest standards. At the same time, the production of green gas increased. By 2015, we were able to supply 1.9 million Nm3 green gas to the gas network, in 2016 that was 2 million Nm3 and in 2017 we exceeded the 2 million Nm3 mark.

Process and facility

Indaver continually works on improvements and innovation and this includes the Bio Power Alphen process and facility. Adjustments have been carried out to reduce the potential odour nuisance in the immediate vicinity. At the same time, Indaver is working on improving the quality of the compost by investing in new screening equipment among other things.

Expanding Capacity

In 2017, preparations started for the revision permit application. This includes expanding the capacity from 75,000 tons to 90,000 tons on an annual basis. An investment study is also underway for taking on streams other than VGF such as liquid, vegetable-based fat streams.
