The fossil fuel-based linear economy has many severe drawbacks, including the need for energy security and the resulting environmental degradation. In a new cycle of the bio-economy that is becoming increasingly important, biomass waste has been used to generate energy while reducing pollution and greenhouse gas emissions. The growth of renewable energy will be substantial in the reduction of greenhouse gas emissions in order to achieve the ambitious goal of becoming carbon neutral by the

The cattail fresh and dry biomass substrate with pig wastes as inoculum was tested for biogas production. Cattail's highly complex lignocellulosic structures make it challenging to decompose as a biogas substrate. Alkaline pretreatment is one of the efficient tools in solubilizing lignin. As a result, chemical pretreatment of biomass (2 % sodium hydroxide) was a unique method for increasing biogas generation by reducing complex polymers of lignocellulosic materials into simpler molecules that microorganisms could digest. The fresh and dry biomass substrate added fermenter was produced with 57% and 60% methane, respectively.
