1. Land-use competition and agricultural greenhouse gas emissions in a climate change mitigation perspective
Abstract : Productive land for food production, bioenergy, or preservation of nature is a limited resource. Climate change mitigation puts additional pressure on land via higher demand for bioenergy to replace fossil fuels and via restrictions on deforestation—two processes that limit the availability of land for food produc- tion, and may thus also raise food prices.

5. Heat-transfer Enhancement for Slurries from Biogas Plants− Properties, processes, and thermal systems
Abstract : Biomethane production from renewable residues with anaerobic digestion gains increasing attention as a crucial alternative to petroleum fuels. It has been vigorously developed, but the large amounts of subsidy from the government indicate that the process efficiency needs to be further improved. READ MORE
