“…The crop residue is the major source in producing biochar, utilizing the crop residue with an appropriate technique can produce vast biochar with the available crop residues. The application of biochar can help improve the function in the carbon sink of agricultural sector because it can not only aggregate the SOC but also absorb the inorganic carbon (i.e., CO 2 ) that exists in the air (Li et al 2017) and improve the air quality (e.g., mitigation in nitrogen oxides, methane, and PM2.5) (Pourhashem et al 2017). The second trigger of SOC loss is management practice as well as soil disturbance.…”

Compared with the conventional fossil fuel, bioenergy has obvious advantages due to its renewability and large quantity, and thus plays a crucial role in helping defend the energy security. However, the bioenergy development may potentially cause serious environmental alterations, which remain unclear. The study summarizes the environmental impacts of bioenergy production based on the compilation and published data. Our analysis shows that more and more attention is being paid to the environmental protection as the development of bioenergy, and among the influencing terms of bioenergy production, water issues (i.e., water quantity and quality) gain the greatest concern, whereas the least attention has been given to soil erosion. Although we recognize that the bioenergy production can indeed exert negative effects on the environment in terms of water quantity and quality, greenhouse gas emissions, biodiversity and soil organic carbon, and soil erosion, the adverse impacts varied greatly depending on biomass types, land locations, and management practices. Identifying the reasonable cultivation locations, appropriate bioenergy crop types, and optimal management practices can be beneficial to environment and sustainable development of bioenergy. In this field, Chinese bioenergy production has lagged behind and does not match its rising energy consumption, but it has a great potential of and demand for biomass-based energy especially under its urbanization, in spite of the negative environmental impacts. Therefore, this article is expected to serve as a reference and guideline on what has been done in the bioenergy-oriented countries that might stimulate development of more effective and environmentally sound guidelines for promoting bioenergy production in China and other developing countries as well.

“…Biomass properties impacts on the process economics for wood and straw feedstock are consistent with the impacts on the pyrolysis fuel yields, as predicted by Li et al . However, the biomass O/C impact on biochar yield overrides the impact on fuel output for grass type of feedstock due to a high willingness‐to‐pay biochar price predicted for grass type feedstock in Jackson (FL). A higher O/C ratio of biomass has the potential to increase fuel yields but decrease the biochar yields, but a high biochar willingness‐to‐pay price will further lead to an increasing MFSP with higher O/C.…”

“…One of the major findings from the GHG emissions in this study is over 64% of the 304 cases of feedstock have the potential to produce carbon‐negative energy, compared to Li et al . who reported less than 1% of 346 cases . The majority of negative GHG scenarios result from the consideration of different biochar carbon content varying feedstocks.…”

“…The consumed energy‐related emissions are also different due to biofuel production variances among different feedstock. Emissions from external energy consumption could be further reduced if replacing with auto‐thermal pyrolysis …”

“…We incorporated our process model with regression models generated by Li et al . to quantify the relations between the biomass properties and pyrolysis products, and further evaluate the economic performance of the pyrolysis‐bioenergy‐biochar platform within a wide range of biomass. The representative biomass properties are chosen as O/C and ash content.…”

This study investigates the sensitivity of greenhouse gas (GHG) emissions and the minimum fuel selling price for a 2000 metric ton day −1 integrated pyrolysis-bioenergy-biochar platform with respect to the biorefinery location and biomass types. The regional techno-economic and life-cycle analysis is evaluated in three US counties using representative crops: rice in Glenn County (California), corn in Hamilton County (Iowa), and peanuts in Jackson County (Florida). We evaluate the biochar selling price considering crop yield increases of 0.6%, 2.9%, and 10% after biochar application over 20 years in Glenn County, Hamilton County, and Jackson County, respectively. The biochar prices are calculated under low and high commodity prices to determine upper and lower bounds. Jackson County has the most economically beneficial scenario with an average minimum fuel selling price (MFSP) of $1.55 gal −1 of biofuel produced whereas Hamilton County has the highest average MFSP of $3.82 gal −1 . The life-cycle analysis shows that woody biomass has a strong potential to produce carbon-negative energy compared to grass and straw. Of the 304 cases scenarios considered for this platform, 64% could produce biofuel with negative GHG emissions, which would meet the Renewable Fuel Standard (RFS) target for cellulosic biofuels.
