Project subpage

An alternative to conventional sewage sludge composting technology is vermicomposting, when manure worms are placed into the starting material, so the efficiency of breakdown and transformation of organic matter is increased by the activity of worms. Compared to conventional composting, higher-quality product can be produced with vermicomposting concerning agronomical value because of the properties of the finished material such as favourable particle size distribution, more easily available nutrients for plants and presence of plant growth stimulating compounds, high metabolic enzyme activity, better quality humic acid and humic substance content. In addition, worms are able to extract certain inorganic contaminants and accumulate them in their bodies, as well as to promote the breakdown of organic pollutants.

The main goal of the project was the development of sewage sludge vermicomposting technologies based on conventional composting. The potentials and limits of vermicomposting were observed in small- and pilot scale prism experiments throughout the project.

The method created in the project deemed successful in reducing all the contaminants specified in hungarian regulations Edict 50/2001 (IV.3) and FVM decree 36/2006 (V.18) (the starting material exceeded the limit values set in those regulations in regard of mineral oil content (TPH), copper content and soil hygiene parameters).
