“…Feedstock cost is effected by feedstock production, collection, pre-treatment (e.g. chipping) and transportation distance (Roy & Dias, 2017). The feedstock cost has a substantial impact (21.3 %) on MSP as reported by Carrasco and colleagues (2017).…”

“…Carbon footprint (CF), a tool to quantify the total GHG emissions of a product or activity, has been used widely to assess all the GHG emissions of crop production over the full life cycle (Roy & Dias, 2017). Carbon footprint of crop production was generally quantified by considering all the GHG emissions induced by or associated with agricultural material used, farm machinery operated, and irrigation power expended and direct field GHG emissions in a crop's life cycle.…”

Biochar soil amendment (BSA) had been advocated as a promising approach to mitigate greenhouse gas (GHG) emissions in agriculture. However, the net GHG mitigation potential of BSA remained unquantified with regard to the manufacturing process and field application. Carbon footprint (CF) was employed to assess the mitigating potential of BSA by estimating all the direct and indirect GHG emissions in the full life cycles of crop production including production and field application of biochar. Data were obtained from 7 sites (4 sites for paddy rice production and 3 sites for maize production) under a single BSA at 20 t/ha−1 across mainland China. Considering soil organic carbon (SOC) sequestration and GHG emission reduction from syngas recycling, BSA reduced the CFs by 20.37–41.29 t carbon dioxide equivalent ha−1 (CO2‐eq ha−1) and 28.58–39.49 t CO2‐eq ha−1 for paddy rice and maize production, respectively, compared to no biochar application. Without considering SOC sequestration and syngas recycling, the net CF change by BSA was in a range of −25.06 to 9.82 t CO2‐eq ha−1 and −20.07 to 5.95 t CO2‐eq ha−1 for paddy rice and maize production, respectively, over no biochar application. As the largest contributors among the others, syngas recycling in the process of biochar manufacture contributed by 47% to total CF reductions under BSA for rice cultivation while SOC sequestration contributed by 57% for maize cultivation. There was a large variability of the CF reductions across the studied sites whether in paddy rice or maize production, due likely to the difference in GHG emission reductions and SOC increments under BSA across the sites. This study emphasized that SOC sequestration should be taken into account the CF calculation of BSA. Improved biochar manufacturing technique could achieve a remarkable carbon sink by recycling the biogas for traditional fossil‐fuel replacement.

“…Meanwhile fast pyrolysis at a temperature of 450-550 • C at a very high heating rate (10-1000 • C/s) for a very short residence time is an option to obtain approximately 70% bio oil, 15% bio char and 15% gas. The yield efficiency of the pyrolysis process depends on the feedstock, process configuration, and conditions [46,48].…”

Solid Fuel from Oil Palm Biomass Residues and Municipal Solid Waste by Hydrothermal Treatment for Electrical Power Generation in Malaysia: A Review

Malaysia generated 156,665 gigawatt-hours (GWh) of electricity in 2016 of which the biggest share of 48.4% was sourced from coal and coke. Malaysia coal consumption was met by 90.5% of imported coal due to high demand from the power sector. Malaysia also has a vast biomass resource that is currently under-utilised for electricity generation. This paper reviews the potential of oil palm residues and municipal solid waste (MSW) for alternative coal replacement employing hydrothermal treatment (HTT). In 2017, about 51.19 million tonnes (Mt) of oil palm waste was available with 888.33 peta-joule (PJ) energy potential to generate 88.03 terawatt-hours (TWh) electricity from oil palm fronds (OPF) and oil palm trunks (OPT), empty fruit bunch (EFB), mesocarp fibre (MF), palm kernel shell (PKS) and palm oil mill effluent (POME). Meanwhile, the MSW energy potential and electricity generation potential was estimated at 86.50 PJ/year and 8.57 TWh/year, respectively. HTT with washing co-treatment eliminates the use of drying for converting range of biomass and MSW into clean solid fuel known as hydrochar. The hydrochar increased in caloric value with lower moisture, Potassium (K) and Chlorine (Cl) contents. These value-added fuels can be used as coal alternative and reduce dependency on imported coal for energy security in Malaysia.
