“…A third, alternative means to dispose of excess biomass is controlled pyrolysis for energy production, which produces biochar (charcoal) as a byproduct (Rutberg et al, 2011;Wu et al, 2009;Manyà, 2012). Although the environmental benefits of this latter approach are well appreciated, it still remains a fairly expensive approach for many small-scale growers.…”

Abstract. Recently, the potential for biochar use to recapture excess nutrients from dairy wastewater has been a focus of a growing number of studies. It is suggested that biochar produced from locally available excess biomass can be important in reducing release of excess nutrient elements from agricultural runoff, improving soil productivity, and longterm carbon (C) sequestration. Here we present a review of a new approach that is showing promise for the use of biochar for nutrient capture. Using batch sorption experiments, it has been shown that biochar can adsorb up to 20-43 % of ammonium and 19-65 % of the phosphate in flushed dairy manure in 24 h. These results suggest a potential of biochar for recovering essential nutrients from dairy wastewater and improving soil fertility if the enriched biochar is returned to soil. Based on the sorption capacity of 2.86 and 0.23 mg ammonium and phosphate, respectively, per gram of biochar and 10-50 % utilization of available excess biomass, in the state of California (US) alone, 11 440 to 57 200 tonnes of ammonium-N and 920-4600 tonnes of phosphate can be captured from dairy waste each year while at the same time disposing up to 8-40 million tons of excess biomass.

“…Recently, there is a study suggesting that using plasma arc as the supporting heating source for gasification can keep a desired range of temperatures, solving the problem of physical variance in a high-moisture biomass feedstock, since plasma arc can build up temperatures higher than 1,500 °C and increase the reaction rate. 7 Moreover, the heat from plasma arc can compensate the heat losses in the system 8 and reduce an amount of tar in the biomass. 9 Nonetheless, an application of plasma arc technology in a heating process in order to improve gasification system is little found in literatures and most of them were carried out in the laboratory scale.…”

Gasification of biomass has been widely used for energy production. However, biomass feedstock must be low in moisture (< 20 % w.b.), inevitably requiring drying process which is both energy and time consuming. This paper shows the potential of high-moisture biomass gasifying using plasma arc as an external heat supply. It was found that high-moisture biomass can be used as feedstock in the plasma-assisted gasification process. The plasma arc maintained gasifier temperature high enough for reactions involved. The efficiency of the plasma-assisted gasification system operated with high-moisture biomass was more or less the same with that of conventional gasification operated with low-moisture biomass. When the drying energy was taken into account, the efficiency of the plasma gasification system is 15% higher than that of conventional gasification system. Overall, the plasma-assisted gasification system can be operated with high-moisture biomass efficiently and reduces the processes and energy for biomass preparation.

“…syngas, in which one can recover up to 80 % of the chemical energy contained in the organic matter initially treated. Based on these performances, a plasma gasifier associated with a gas turbine combined cycle power plant can target up to 46.2 % efficiency [32]. Moreover, this synthesis gas produced by gasification, mainly composed of CO and H 2 can also be used as feedstock for the production of synthetic liquid fuels in processes such as Fischer-Tropsch process.…”

waste gasification processes based on thermal plasma (DC or AC plasma torches) at lab scale versus typical performances of waste autothermal gasification: LHV of the syngas, cold gas efficiency and net electrical efficiency. In the last part, a review has been done on the various torch technologies used for waste gasification by plasma at industrial scale, the major companies on this market and the perspectives of the industrial development of the waste gasification by thermal plasma. The main conclusions are that plasma technology is considered as a highly attractive route for the processing of waste-to-energy and can be easily adapted to the treatment of various wastes (municipal solid wastes, heavy oil, used car tires, medical wastes …). The high enthalpy, the residence time and high temperature in plasma can advantageously improve the conditions for gasification, which are inaccessible in other thermal processes and can allow reaching, due to low tar content in the syngas, better net electrical efficiency than autothermal processes.
