Summary:
A Hungarian SME with several years experience in composting procedures has developed a new, more useful and environmentally friendly technology for sewage sludge composting, which can be useful for sewage works or town management of regional governments. The end-product of the process has a high fertilising value, organic matter and harmonious trace element content. The company is interested in licence or commercial agreement supported by technical assistance.
Details:
The composting technology offered by the Hungarian company is suitable for composting sewage sludge. It is based on the application of controlled composting for rapid degradation of
organic pollutants and immobilization of inorganic micro-pollutants for safe land disposal by using industrial slurry-phase by-products (e.g. by-products from sunflower seed oil processing industry).
The process of controlled composting contributes to preserve the fertilizer value. Before the composting, the untreated sewage sludge is mixed with waste sludge (e.g. sludge produced by sunflower seed oil processing industry) and other specific additives to accelerate mineralization and to moderate ammonia and GHG (greenhouse Gas) emission. In some cases composting simulation is used for optimalisation of raw material composition and gas emission controlling within 3 weeks in an adiabatic drum system. Composting occurs under controlled condition which means that additives, digesters and labile carbon sources are added continuously to the compost pile.
Specific additives are responsible for the suitable and rapid mineralization and thermophilic stage to preserve fertilizer value. Depending on the properties of raw materials encapsulated windrow composting is applied for controlled composting which means a covering of compost pile by using specific polymers. The end-product is a potential source for soil improvement and conditioning after 4-pre- and 6-week-term post maturation stages. The whole composting process is not longer than 70-90 days.
Current and Potential Domain of Application: The offered technology can be used by sewage works or the city management of regional governments.
The Hungarian firm is looking for industrial partners interested in licence or commercial agreement with technical assistance.
Type and Role of Partners Sought:
- Type of partner sought: industrial partners interested in licence or commercial agreement supported by technical assistance.
- Specific area of activity of the partner: industrial partner dealing with waste management, recycling, sewage works, city management.
- Task to be performed by the partner sought: sewage works or the city management of regional governments.
