Partner KTU APINI presents results from research on ENERCOM solid recovered fuel

With the objective of assessing possibilities to produce solid recovered fuel from a composted mixture of pre-treated sewage sludge and biomass residues KTU APINI members tested and analyzed samples of pellets and briquettes.

Pellets produced at ENERCOM trial

As one output of the ENERCOM project stands the general question whether recovered fuel from sewage sludge and greenery waste could replace peat as a fuel. The use of peat for energy is in conflict with protection of natural habitats as well as natural CO2 buffering systems and therefore questioned. In Finland and the Baltic states however peat is a major source of energy production.  The recovered fuel produced in ENERCOM pilot plant has the potential to replace peat as a fuel.

KTU APINI as the Lithuanian partner of ENERCOM therefore performed tests with samples of pellets and briquettes produced in Luxembourg ENERCOM plant. Technical and environmental evaluations of solid recovered fuel production were carried out. Main chemical and physical parameters of produced solid recovered fuel were analyzed and compared to the recovered fuel classificatory (CEN/TC 343). All pellets and briquettes, produced during the experiment, were attributed to a certain class of recovered fuel.

The results are presented in the paper “Generation of Solid recovered fuel from Sewage Sludge Compost” which was published at the journal “Environmental Research, Engineering and Management”, Vol. 62 No 4 (2012).

The paper, written by Irina Kliopova and Kristina Makarskienė gives insides into the feasibility of producing pellets and briquettes using the composites of compost, sawdust, and peat and presents results of the research which was carried out in KTU APINI when implementing one stage of the FP7 program project “Polygeneration of energy, fuels, and fertilizers from biomass residues and sewage sludge (ENERCOM)”
