Evaluation of energy potential in compost with proportion of grape marc

Original language description

Rising interest in the use of energy biomass is leading to the search for new renewable energy sources, which can also include compost. According to current knowledge, compost is primarily an organic fertilizer, but it can also be used as a solid biofuel with good energy potential. For the needs of experimental measurements focused on calorimetric calorific values, 3 variants of mature compost were used. Two variants consists from a mixture of horticultural waste in combination with 25 and 50% grape pomace content. Changes in the calorific value of compost were determined with reference to the particle size distribution and also with regard to the humidity, which was set in the laboratory at 0, 15, 30 and 45%. The desired humidity was achieved by adding the required amount of deionized water to the dried compost. The obtained results show that grape pomace, as an input raw material added to compost bins, together with moisture, can significantly affect the resulting calorific value of compost. In the case of dried variants of compost with a proportion of grape pomace, it was at the level of 9.08-11.06 MJ/kg. In the control variant at the level of 6.18 MJ/kg, with increasing humidity, the calorific value decreases significantly. The reason for the higher calorific value in compost with a content of grape pomace is the presence of grape seeds with a part of oily components, which remain undecomposed during the composting process.
