Estimation of Biomass Resources Potential

Abstract

: Biomass has been used for energy sources from the prehistoric age. Biomass are converted into solid, liquid or gaseous fuels and are used for heating, electricity generation or for transportation recently. Solid biofuels such as bio-chips or bio-pellet are used for heating or electricity generation. Liquid biofuels such as biodiesel and bioethanol from sugars or lignocellulosics are well known renewable transportation fuels. biogas produced from organic waste are also used for heating, generation and vehicles. Biomass resources for the production of above mentioned biofuels are classified under following 4 categories, such as forest biomass, agricultural residue biomass, livestock manure and municipal organic wastes. The energy potential of those biomass resources existing in Korea are estimated. The energy potential for dry biomass (forest, agricultural, municipal waste) were estimated from their heating value contained, whereas energy potential of wet biomass (livestock manure, food waste, waste sludge) is calculated from the biological methane potential of them on annual basis. Biomass resources potential of those 4 categories in Korea are estimated to be as follows. Forest biomass 355.602 million TOE, agricultural biomass 4.019 million TOE, livestock manure biomass 1.455 million TOE, and municipal organic waste 1.074 million TOE are available for biofuels production annually.

Identification of differences and comparison of fuel characteristics of torrefied agro-byproducts under oxidative conditions

“…Agricultural by-products are advantageous owing to their continuous production. In 2021, domestic wood pellet production amounted to 658,336 tons, while imported wood pellets accounted for 3,178,560 tons, making up 82.84% of the total pellet consumption in the country [ 1 ]. Devices for collecting agricultural by-products have been developed to use this biomass [ 2 ].…”

Agricultural Land: Crop Production or Photovoltaic Power Plants

“…The solving of this problem requires using energy management planning [10,11]. The use of abandoned cropland for creating renewable energy infrastructure is a promising solution to reduce competition for arable land [12][13][14].…”
