Synergy of anaerobic digestion and pyrolysis processes for sustainable waste management: A critical review and future perspectives

The organic residues generated in grasslands can be treated by adopting anaerobic digestion technology. This technology can enhance the efforts for sustainable waste management around the world. In the northern Netherlands, there is a vast amount of ditch clippings and canal grasses that can be used as a renewable source of energy; however, optimal bioenergy production from grasses is still under research and this study aims to evaluate biogas production from grassy residues at the local level in the context of a sustainable waste management scheme. Batch tests were facilitated to investigate the impact of temperature and organic load on the anaerobic digestion performance of grass mixtures (ditch clippings and canal grasses). The results showed that high temperature favors the degradation of high lignocellulosic materials like grasses. Specifically, bioreactors at 55 °C with an organic load of 30 g volatile solids (VS) L−1 reached 360.4 mL g VSsubstrate−1. Moreover, reactors with low organic loads resulted in a lower methane yield. The kinetics study also showed good fitting of the predicted and experimental values.

Environmentally Sound

Sustainable waste management of biodegradable waste is one of the serious concerns in developing countries. The energy production from organic waste material by anaerobic digestion (AD) is environmentally sound, energy-efficient, and economical technology that degrades substrate, with minimum production of harmful metabolites, and reuse of its byproducts as bio-fertilizers. The use of small-scale biogas digesters in developing countries and industrial scale or integrated biogas digesters in developed countries has been operationally upgraded. These advancements in the application of AD processes are due to multiple factors, including the economic and environmental value of AD technology, and the dynamics of a range of policies and measures related to agricultural sector, waste control, and green energy production. However, compared to other waste management and energy generation methods, AD requires fewer resources and cost investment, and is therefore sustainable for waste control and energy production.
