Requirements for compost in line with proposals from scientists


A study commissioned by the Ministry of Environment and developed by scientists will help to determine quality and contamination requirements for composts and anaerobic digestate made from various biodegradable wastes.

According to Dalius Krinickas, Director of the Waste Department of the Ministry of Environment, in Lithuania digestate is produced mostly from livestock manure, green waste, food waste and waste of the food industry, putrefied and non-putrefied wastewater sludge, etc. Anaerobic digestate is a residue of biogas production. The manufacture of these products is on the rise in Lithuania as the number of facilities for biodegradable waste treatment is increasing. The amount of compost and digestate will enlarge even more from 2019 when Lithuania is to launch the separate collection and treatment of food waste.

The research institutions that prepared the study, in particular the Agrochemical Research Laboratory, a branch of the Lithuanian Research Centre for Agriculture and Forestry, and UAB EcoIri Solution, obtained samples of composts and digestate from 54 installations of biodegradable waste management: green waste composting sites, wastewater sludge and manure treatment plants, etc. Based on the research results, the scientists have proposed criteria according to which composts and digestate can be attributed to products rather than waste, as well as standards and recommendations for their use.
