Abstract:

Large amounts of wood charcoal have been used in the past as feedstock for many industry sector, (energy, metallurgy, C extraction) but it has been replaced year by year by fossil coal, coke and synthetic materials. This trend characterised by coal consumption growth contributed rapidly to a wide range of damaging effects influencing European population and environment health (Global warming, ecosystem loss and degradation, loss of air, water pollution, respiratory admissions, etc..). All in the name of cost reduction. In fact, virgin forestry wood, usually consumed for charcoal production, is a high quality material with several valuable applications like construction, domestic heating, paper industry. For this reason, virgin wood is now traded at a cost of no less than 80 €/ton. Consequently, wood charcoal market price is not set below 250 €/t. This high market price avoids the use of wood charcoal in large market sectors where high amount of carbon, at low cost, are consumed, and where fossil coal has now fully replaced charcoal. One of these sectors is the Metallurgy and Steel industry. The development of new technologies recently brought to a big change in the renewable solid carbon sources. In particular, hydrothermal carbonisation technology, developed by INGELIA SL, demonstrated to be able to process wet low value biowaste streams, like municipal biowaste and food waste, producing a new biocoal, named hydrochar, which could represent an unlimited source of renewable carbon, at competitive price, for even large industry sectors. This study is focused on the characterisation, basic and process performances of three hydrochar samples obtained from INGELIA industrial Hydrothermal Carbonisation plant, from Green Waste (GW), Organic Fraction of Municipal Solid Waste (OF) and Orange Peel (OP). USTB executed performance tests on these three hydrochar samples, comparing them with two fossil coals: a typical bituminous coal, and anthracite, in order to evaluate the potential use of hydrochar as renewable fuel for the blast furnace injection.
