Impact of Starch from Cassava Peel on Biogas Produced through the Anaerobic Digestion Process
This study investigates the impact of cassava peel starch on biogas production via anaerobic digestion. Utilizing beating pre-treatment to isolate starch, temperature, volatile solid, and sludge quantity effects were analyzed using Design of Experiments. Results indicate starch has minimal influence on biogas quality, with maximum biogas volume at 3830 cc and CH4 production at 850 cc g−1-VS, suggesting potential energy gains.

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.

Biogas from cassava peels waste
The study investigates biogas and biofertilizer production from cassava peels waste inoculated with cow dung in Nigeria. Various pretreatment chemicals were used, and six batch anaerobic biodigesters were employed for 40 days. Stale cassava peels with NH4Cl pretreatment yielded the highest biogas production (2540 cm3/day) and methane yield (62.3%). Digester sludge demonstrated good biofertilizer qualities.

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.
