MISCANTHUS AND MAIZE STALK AS SOURCE FOR GREEN ENERGY PRODUCTION

Rising concerns about fossil energy and its impact on the environment have accelerated the development of bioenergy on a global level since biomass is a long-term renewable and CO2 neutral. The use of biomass resources for energy purposes will reduce the dependence on fossil fuels and provide a way to mitigate climate change. Miscanthus and maize stalk will be investigated to be used for energy production by direct combustion. Maize stalk as postharvest residues and energy crop Miscanthus x giganteus belong to the second generation biomass (lignocellulosic biomass), but also to C4 plants, and such biomass is a potentially high-value source for green energy production. This study aims to determine the miscanthus and maize stalk biomass energy properties (structural, ultimate and proximate analysis and heating) as feedstock in the process of biofuel production. Namely, the characterization of these components, both qualitative and quantitative, is essential for defining the further processing of biomass into biofuels. Ash with moisture is a fundamental component of the non-combustible matter and 4, 40% share for maize stalk and 1, 96 for miscanthus is better than the most agricultural biomass., The most significant components of combustible matter are carbon and sulfur, and their values of approx. 47% and 0.2%) indicate good quality of the investigated raw material. The structural composition indicates the potential for use in the production of liquid fuels but also in the production of solid fuels. The lower heating value of maize stalk was 15 MJkg-1 while lower heating value of miscanthus biomass was 17 MJkg-1. Based on above results it can be concluded that investigated biomass has great potential as raw material for green energy production.
