Potential of bio-drying for generation of solid recovered fuel from wet organic substrates
No full textBio-drying is one of the aerobic processes available for waste management. Its aim is the modification of the waste characteristics to increase its Lower Heating Value (LHV). An additional advantage is the easier removal of glass, metals and other inert materials from MSW through a post-selection giving a Solid Recovered Fuel (SRF) as output. In this paper, results of pilot-scale bio-drying, applied to residual MSW (RMSW), to sewage sludge mixed with MSW and to exhausted grape marc alone, are presented in order to understand the potential of bio-drying for wet organic substrates valorisation. In case of RMSW bio-drying, post-selection acts as a second step of energy concentration, giving a result highly depending on the residual MSW food waste (FW) content, that is affected by the strategy and efficiency of selective collection (SC): after 14 days, the increase of LHV resulted +24% in case of FW=50% but only +7% in case of FW=8%. The experimental run of sludge co-bio-drying demonstrated how the final result depends on its moisture and stabilization. In case of exhausted grape marc, the reached LHV (+20% in 14 days) demonstrates that grape marc can be converted in a SRF, having in general low Chlorine and Mercury content
Thermal treatment options for the Romanian municipal solid waste: energy balances
No full textIn Romania the impact of waste on the environment has increased at an alarming rate during the past decades also because of an inadequate management of the generated waste. One of the thermal options that can better this situation is based on the concept of municipal solid waste bio-drying pre-treatment in order to open to a group of solutions alternative to direct combustion for energy recovery. This paper presents the results of energy balances based on the average characteristics of the Romanian municipal solid waste. Interesting results could be obtained exploiting existing industrial plants that could partially substitute conventional fuels by refuse derived fuel. One of the problem of this strategy is the potential generation of residues to be landfilled when a high quality fuel must be generated. The lower heating value obtainable by bio-drying and simplified post-treatment can overcome 15 MJ/kg while an additional post-treatment can allow reaching values higher than 20 MJ/kg
