Circular economy use of biomass residues to alleviate poverty, environment, and health constraints

Abstract

Inadequate energy and water resources supply are major constraints contributing to poverty and poor health outcomes in developing economies. Low-income countries lack ready access to modern necessities such as electricity and potable water. On one hand, the scarcity of electricity and other clean energies compel reliance on traditional biomass for domestic fuels. On the other hand, harvesting firewood to meet energy needs leads to deforestation and environmental degradation. Furthermore, burning the wood for heat creates ecosystem perturbators such as toxicants, greenhouse gasses, and particulate matter. These pollutants portend adverse health concerns, including premature mortality. Globally, fine particulate matter air pollution alone causes about 3.3 million deaths annually. The contribution of this paper is to offer how circular economy targeted technologies could come to the rescue. In particular, utilizing biomass residues and wastes for briquette and pellet creation is highlighted. These densified fuel products could serve as green energies in domestic and industrial applications; and thus, help to attenuate poverty, and the adverse environmental and health consequences of traditional biomass.
