Dutch organic waste and biomass recycling operator Comgoed earns RHP certification

Comgoed, an organic waste and biomass recycling operator, has achieved RHP Consumer certification with its new raw material: spent substrate. RHP is the Dutch certification scheme for substrates and raw materials.

With the certification of Comgoed, RHP welcomes its 75th certified company! Comgoed is also the first company to receive the RHP certificate for ‘spent substrate’.

Based on research and inspections executed by the certification body, the company complies with the requirements as determined in the Product Certification Scheme of the RHP quality mark.

The certification of Comgoed brings the total of RHP certified companies to 75 companies worldwide.

Comgoed Substrates BV is based in Middelharnis, 50km south west of Rotterdam and was founded in 2022. The company’s core business is composting plant-based residual streams. The company’s Quality, Health, Safety, and Environment’ (QHSE) manager Thijs Fleuren says, “We supply our products to the substrate industry, greenhouse horticulture and tree nurseries. RHP certification is a confirmation for us that we consistently manage our process and deliver high-quality compost products that meet the strictest quality standards.”

The raw material ‘spent substrate’ with the RHP quality mark complies with strict requirements to ensure the highest quality. For RHP-certified ‘spent substrate’, a careful selection is applied to determine which streams of strawberry growers are suitable for the sanitation and processing in growing media. Additional requirements are imposed on the composting process under the RHP quality mark to achieve proper sanitation. Due to its many positive properties, RHP-certified ‘spent substrate’ is broadly applicable in RHP Consumer-certified potting soils.
