Energy efficient alternatives to decarbonize the pulp and paper industry – the case of linerboard production

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Variability in fossil fuel prices and a commitment to reducing greenhouse gas (GHG) emissions have driven the US pulp and paper (P&P) industry to adopt technologies that decrease reliance on fossil fuels. In this regard, enhancing energy efficiency is crucial to the decarbonization of the sector.

Potential of sugarcane bagasse as feedstock for biogas production in Nigeria

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The Nigerian government's interest in expanding the sugar sector has significantly increased sugarcane production, generating substantial bagasse by‐products without adequate waste management strategies. This study examined the potential of sugarcane bagasse as a biogas feedstock by integrating a socioeconomic survey of 120 sugarcane farmers ...
