Bio-transforming Cassava Pulp into Valuable Volatile Fatty Acids as Renewable and Inexpensive Substrates for Biogas and Bioplastic Prospects
Thailand's cassava pulp (CP) waste presents a significant agro-industrial challenge, but it also holds untapped potential for producing valuable volatile fatty acids (VFAs). This study explores an innovative CP waste management approach that leverages microbial fermentation to produce acetic and butyric acids, key components in biogas, bioplastics, and bio-based chemicals. By enriching a microbial consortium with acid-tolerant Clostridium species, the process achieves high VFA yields with low operational costs, reducing greenhouse gas emissions. This method offers a sustainable solution with the potential to generate millions of tons of VFAs annually, supporting a shift toward greener, circular economies.

Biogas production from waste pulps of cassava (Manihot esculenta Crantz) via anaerobic digestion
Cassava waste pulps (CWPs) from starch industries demand attention for sustainable disposal. This study explores anaerobic digestion of CWP with pig manure, optimizing conditions for biogas production. Gas chromatography reveals significant biohydrogen concentration (18.69 ± 1.71%), offering promising, low-emission energy. CWPs show potential for valuable biogas generation, benefiting both industry and environment.

Evaluation of the environmental performance of bioethanol from cassava pulp using life cycle assessment
This study assesses the environmental impact of bioethanol from cassava pulp as transport fuel. Optimal scenarios include biogas use for steam and economic pulp allocation. Ethanol outperforms gasoline in greenhouse gas reduction, with E85 yielding the highest savings. Despite E85's negative effects on certain aspects, its overall impact remains lower than gasoline.

Economic and Environmental Assessment of Different Biogas Conversion Technologies for Cassava Pulp Treatment in Thailand: A Case Study
This study examines the economic and environmental impact of various biogas conversion technologies for cassava pulp treatment. Anaerobic cover lagoon (ACL), modified cover lagoon (MCL), and anaerobic baffled reactors (ABR) emerged as most suitable based on investment cost. ACL and MCL offer high NPV, IRR, and short payback periods due to low overall costs.
