Recent advancements in the evolution, production, and degradation of biodegradable mulch films: A review

Biomass-based plastic production systems play a crucial role in fostering a sustainable society. Biodegradable mulch films (BDMs) have emerged as a practical solution to environmental pollution in agriculture. Various types of BDMs, including polybutylene adipate-co-terephthalate, polybutylene succinate, and polybutylene succinate-co-adipate, have been developed, though many are still derived from fossil-fuel-based plastics. Furthermore, the adoption of biodegradable materials in agricultural practices remains limited. This review critically assesses the evolution and significance of mulch films, highlighting the transition from traditional polyethylene (PE) to BDMs in response to environmental challenges. We provide an overview of the biorefinery approach to producing biomass-derived BDMs, discussing biomass pretreatment, saccharification, production of plastic monomers using microbial cell factories, purification, and polymerization. The review also explores techniques to enhance the biodegradation capabilities of mulch films during polymerization. Additionally, we emphasize the necessity for advancements in controlling the degradation rates of BDMs. By addressing the environmental concerns associated with the disposal of these materials, this review underscores the importance of developing effective strategies for a more sustainable and environmentally friendly agricultural landscape.
