“…In the agricultural sector, livestock manure represents a substantial source of readily-collectable biomass, however, improper disposal causes odour problems, release of pathogens, contamination of surface and groundwater as well as methane and ammonia emissions [3]. The anaerobic digestion of manure decreases pathogenic bacteria and enhances the agronomica1 va1ue of the residue [4,5] thereby reducing the negative environmental impact it can have.…”

Biosolid Management Options in Cassava Starch Industries of Thailand: Present Practice and Future Possibilities

Greenhouse gas (GHG) emissions from the existing biosolid management practices in cassava starch industries of Thailand have been evaluated and compared with other biosoild management options with a view to reduce GHG emissions and possible energy recovery. The study involved development and application of a spread-sheet based evaluation tool to estimate GHG emissions, benefits such as GHG offsets and possible energy recovery from four different cassava pulp waste management options viz.: (i biodrying followed by production of refuse derived fuel (RDF), (ii) composting, (iii) anaerobic digestion with energy recovery and (iv) landfilling with energy recovery. Parameters such as GHG emissions, benefits in terms of GHG mitigating potential and energy recovery ton -1 of cassava pulp waste were determined for each biosolid management option. Total baseline emissions from the existing cassava biosolid management practices were estimated as 4.2 kg CO 2 eq. ton -1 of cassava pulp waste. Among the four waste treatment alternatives, biodrying followed by RDF production scenario showed the highest GHG mitigating potential of 85.2 kg CO 2 eq. ton -1 cassava pulp. On the other hand, landfill option with biogas flaring resulted in highest net GHG emissions of 28.7 (kg CO 2 eq. ton -1 cassava pulp). Biodrying followed by RDF has the highest net heat energy gain (NEG) of 1 536 MJ · ton -1 of cassava pulp treated. However, for conversion of waste-to-energy, anaerobic digestion has the highest net energy ratio (NER) for heat as well as electricity recovery with high GHG mitigation potential. © 2015 A.

“…Cassava contains large amounts of starch (20-35% fresh and 80.6% dry weight) [9,10] and total dry matter (38.6%) [11], and has been reported to have the smallest water-footprint (21 m 3 /GJ) compared to all other crops [12]. Based on the above reasons, cassava has recently gained considerable attention for the production of bioenergy [10] and in particular for the production of biogas [13][14][15][16][17].…”
