Will biomass be used for bioenergy or transportation biofuels?

Jinguang HU, William James CADHAM, Susan van DYK, Jack N. SADDLER

《农业科学与工程前沿（英文）》 2017年第4卷第4期页码 473-481 doi: 10.15302/J-FASE-2017168

摘要： Potential competition for biomass for current and future bioenergy/biofuel uses in Brazil, Denmark, Sweden and the USA were compared. In each of these countries, bioenergy and biofuels are already important in their energy mix. However, there is limited competition for biomass between bioenergy (heat/power/residential/industrial) and transportation biofuel applications. This situation is likely to continue until advanced biofuel technology becomes much more commercially established. In each of these countries, biomass is predominantly used to produce bioenergy, even in those regions where biofuels are significant component of their transportation sector (Brazil, Sweden and USA). The vast majority of biofuel production continues to be based on sugar, starch and oil rich feedstocks, while bioenergyis produced almost exclusively from forest biomass with agricultural biomass having a small, but increasing, secondary role. Current and proposed commercial scale biomass-to-ethanol facilities almost exclusively use agriculture derived residues (corn stover/wheat straw/sugarcane bagasse). Competition for biomass feedstocks for bioenergy/biofuel applications, is most likely to occur for agricultural biomass with coproduct lignin and other residues used to concomitantly produce heat and electricity on site at biofuel production facilities.

AGRI-ENVIRONMENTAL ASSESSMENT OF CONVENTIONAL AND ALTERNATIVE BIOENERGY CROPPING SYSTEMS PROMOTING BIOMASS

《农业科学与工程前沿（英文）》 2022年第9卷第2期页码 284-294 doi: 10.15302/J-FASE-2021435

摘要：

Bioenergy, currently the largest renewable energy source in the EU (64% of the total renewable energy consumption), has sparked great interest to meet the 32% renewable resources for the 2030 bioeconomy goal. The design of innovative cropping systems informed by bioeconomy imperatives requires the evaluate of the effects of introducing crops for bioenergy into conventional crop rotations. This study aimed to assess the impacts of changes in conventional cropping systems in mixed dairy cattle farms redesigned to introduce bioenergy crops either by increasing the biomass production through an increase of cover crops, while keeping main feed/food crops, or by substituting food crops with an increase of the crop rotation length. The assessment is based on the comparison between conventional and innovative systems oriented to feed and biogas production, with and without tillage, to evaluate their agri-environmental performances (biomass production, nitrogen fertilization autonomy, greenhouse gas emissions and biogas production). The result showed higher values in the biogas cropping system than in the conventional and feed ones for all indicators, biomass productivity (27% and 20% higher, respectively), nitrogen fertilization autonomy (26% and 73% higher, respectively), methanogenic potential (77% and 41% higher, respectively) and greenhouse gas emissions (15% and 3% higher, respectively). There were no negative impacts of no-till compared to the tillage practice, for all tested variables. The biogas cropping system showed a better potential in terms of agri-environmental performance, although its greenhouse gas emissions were higher. Consequently, it would be appropriate to undertake a multicriteria assessment integrating agri-environmental, economic and social performances.

Achieving food security and high production of bioenergy crops through intercropping with efficient resource

Yuanmei ZUO,Zhenjiao ZHANG,Caihong LIU,Weina ZHANG

《农业科学与工程前沿（英文）》 2015年第2卷第2期页码 134-143 doi: 10.15302/J-FASE-2015069

摘要： With high rates of food and nonrenewable fossil fuel consumption worldwide, we are facing great challenges in ensuring food and energy security to satisfy the world population. Intercropping, as an important and sustainable cropping practice in agroecosystems, has been widely practiced around the world. Many studies have shown that some plants can deliver high yields when intercropped with other plants. Here, we review the biological mechanisms in improving resource utilization efficiency and illustrate the practical application of intercropping in ensuring food and energy security through improving production. Identifying suitable energy plants for marginal land, land not suitable for food crops growth, is an effective strategy to acquire high production of bioenergy, thus removing competition between the use of land for food and energy. The effective application of intercropping provides a potential pathway for production of food crops and energy plants by improving resource use efficiency and resistance to environmental stress.

Bioenergy recovery from landfill gas: A case study in China

Wei WANG, Yuxiang LUO, Zhou DENG

《环境科学与工程前沿（英文）》 2009年第3卷第1期页码 20-31 doi: 10.1007/s11783-009-0012-9

摘要： Landfill gas (LFG) utilization which means a synergy between environmental protection and bioenergy recovery was investigated in this study. Pressure swing adsorption technology was used in LFG purification, and laboratory experiment, pilot-scale test, and on-site demonstration were carried out in Shenzhen, China. In the laboratory experiment, A-type carbon molecular sieve was selected as the adsorbent by comparison of several other adsorbents. The optimal adsorption pressure and adsorption time were 0.25 MPa and 2 min, respectively, under which the product generation rate was 4.5 m /h and the methane concentration was above 90%. The process and optimization of the pilot-scale test were also reported in the paper. The product gas was of high quality compared with the National Standard of Compressed Natural Gas as Vehicle Fuel (GB18047-2000), when the air concentration in feed gas was under 10.96%. The demonstration project was composed of a collection system, production system, and utilization system. The drive performance, environmental protection performance, and economic feasibility of the product gas – as alternative fuel in passenger car, truck, and bulldozer – were tested, showing the feasibility technology for LFG utilization.

木质原料制取先进生物燃料正处在大规模产业化的前夜——迎接生物能源第二波浪潮

程序,石元春

《中国工程科学》 2015年第17卷第1期页码 11-18

摘要：

近年来在欧美国家和地区出现了一批基于热化学平台、糖平台和羧酸盐平台的新型液、气生物燃料企业。其原料和技术路线与先前第一代生物燃油乃至第二代纤维素乙醇所采用的水解-发酵或酯交换工艺完全不同。突出的特点是使用木质纤维类原料，因而能将原来不能充分利用的木质素及半纤维素所含的能量（约占总能的四成）也转化入最终的生物合成油/气之中。从而为大规模利用林木类废弃/剩余物、能源林/灌木和木变油/气提供了前所未有的机遇。当前这些技术绝大部分已通过中试和示范规模的验证，经济可行性较强，正处于大规模产业化的前夜。用它们制取的多种先进生物燃料还有两个非常大的优点，即均属于所谓的“直接使用”类燃料，能以任何比例与常规汽、柴油掺混，或完全单独用于现有的发动机（不用改装发动机），亦无需像乙醇那样须有专用的储运设施；且均有70 %~90 %的CO2减排效果。我国在此领域也出现了好的苗头，在迎接全球生物能源第二波浪潮的激烈竞争中须也能够占有一席之地。
