There is a great number of small- and medium sized sewage plants in and out of the European Union that cannot pass over urban sewage sludge for agricultural use in sufficient proportion (less than 50% in the EU), therefore the management of these sewage plants usually ask and receive permissions from environmental authorities for disposing the communal sludge in disused mines or dumps. Instead of disposal and landfilling – that regularly causes pollution of natural water resources – it would be more beneficial to produce sludge pellets.
Such experiences drove us to create the INNOPELLET technology, a self-supporting biofuel pellet producing system for treating communal sewage sludge that is economical in case of small scale production too.
The development of more and more strict European legislations towards a more sustainable and cleaner handling of urban wastewater creates two types of demands: (1) effective handling and management of sludge coming from municipal wastewater treatment plants without the need to pay costly fines or fees (2) provide additional side-products from the sludge treatment that can be used for own purposes of the plant (e.g.: heating) as integral part of the new circular economy strategy of the European Union
The demand from end-users, especially the needs coming from the EurAsian markets, is continuously increasing, urbanization is closely linked to the problem of managing and treating municipal wastewater treatment sludges, as a result of which demand towards environmentally sound solutions is also increasing. The product standardization in one hand could help to fulfil customer needs quicker on a reasonable price. On the other hand, it gives the possibility to target new segments and new potential customers, other than the municipality segment.
