Abstract

Energy is at the center of the world’s most critical environmental and economic development problems. According to the International Energy Agency (IEA), the world’s primary energy demand, which is 14 billion tons of oil equivalent (TOE), is expected to reach 20.3 billion TOE levels with an increase of 45% in the next 20 years. As of 2016, 81% of the world's primary energy resources are fossil fuels. It is estimated that this figure will reach 79% in 2040. The effects of fossil fuels on climate, health and energy security encourage the conversion to green energy. The sustainable supplies of wood raw material is recognized as a critical resource for tackling climate change and securing energy demand in the global challenge by the IEA, the International Renewable Energy Agency and the Intergovernmental Panel on Climate Change. Wood pellets and briquettes are produced from biomass, and in recent years research has focused on different lignocellulose-based energy sources and ways to increase efficiency. Wood pellet becomes an increasingly crucial alternative fuel for homes, small furnaces and industries with competitive cost and carbon neutrality in producing heat and electricity versus oil or natural gas. Global pellet demand is increased significantly and is expected to reach 100 million tons in 2027.The main features that determine the quality of pellets are humidity, energy value and their effect on environmental pollution. Although wood pellets reduce greenhouse gas emissions compared to fossil fuels, the life cycle of the pellet, from raw material harvesting to ash removal, generates pollution. Wood smoke may contain more than 200 organic compounds that cause acute and chronic health effects and pollute the atmosphere. In this study, human and environmental impacts will be examined, taking into account the increasing demand for bioenergy and the key roles of woody pellets in renewable energy-related environmental policies.
