Biowaste treatment through industrial insect farms: One bioeconomy puzzle piece towards a sustainable net-zero carbon economy?

摘要

Global methane emissions have moved in the last years into the focus of the Climate Change scientific community because of continuing increases of global methane emissions and their contribution to global warming. In 2019, methane emissions reached 260% of the pre-industrial level (WMO, 2020). There exists scientific consensus that due to its high short-term global warming potential, which is about 25 times higher than the warming potential of carbon dioxide (C2ES, 2021), without the substantial reduction of methane emissions the Climate Targets of the Paris Agreement (UNFCCC, 2015), cannot be met.In addition to methane emissions from the fossil energy sector, a large share of methane in the atmosphere has its origin in agriculture and improper organic waste management strategies associated with landfilling of organic waste. This is especially true in developing nations in the subtropical and tropical regions where organic waste separation and landfill gas emission controls are still an exception and where the share of organics in household wastes can exceed 60%.
