Polybrominated diphenyl ethers in atmosphere from three different typical industrial areas in Beijing, China

Three common industries that cause polybrominated diphenyl ethers (PBDEs) pollution in Beijing, China, are solid waste incineration, chemical manufacturing, and coal-fired thermal power generation. This study was conducted to determine both the concentrations and profiles of 42 PBDEs in gaseous and particulate matter (including PM2.5, PM2.5–10, and total suspended particulate (TSP)) from the major industries listed above at three sites in Beijing. The total concentration of PBDEs (defined as the sum of 42 congeners in gas and TSP) were 60.5–216pgm−3 at the solid waste incineration plant, 71.8–7500pgm−3 at the chemical plant, and 34.4–454pgm−3 at the coal-fired thermal power plant. The results indicate that the components of PBDE in gas were similar between three industrial sites, and the dominant congener was tri-BDEs. However, in particulate matter, the dominant BDEs were different between the three sites, possibly because they originated from different sources. In particulate matter, the dominant PBDEs were penta-BDEs at the solid waste incineration plant, deca-BDE at the coal-fired thermal power plant, and tetra-BDEs and deca-BDE at the chemical plant. Source analysis revealed that PBDE contamination might be associated with the use of different commercial PBDE flame-retardant mixtures. Results from a previous risk assessment indicated that the risk to human health was low. However, results from this study suggest that there is a potential threat associated with human exposure to PBDEs for the residents near these industrial sites.

Experimental Study on the Co-Firing Power Generation of Municipal Solid Waste and Biomass

Much attention has been paid to municipal solid waste (MSW) incineration power generation and biomass energy. The co-firing power generation tests of MSW and biomass were performed in a MSW incineration power plant in North China. Experimental results showed that the running efficiency of generator unit had achieved the optimum state when the blended ratio was 14% (w%); the concentration of fly ash decreased greatly, and the concentration of SO2 and NOX increased slightly. These contents can be referenced in the running of MSW incineration power plant and the using of biomass energy later.

垃圾能源化过程中的温室气体减排成本效益分析——以天津为例

垃圾能源化过程不仅仅可以在垃圾处置过程中产生能源，而且减排温室气体。本文以垃圾焚烧发电和填埋气发电两种垃圾能源化方式的温室气体减排为基础，进行了其成本效益分析。识别并描述了垃圾能源化项目的私人成本与环境收益。以天津市垃圾能源化项目为例，核算了天津市垃圾能源化的温室气体减排量，得出利用1吨垃圾进行焚烧发电的减排量为0.777 tCO2e，进行填埋气发电的减排量为0.657 tCO2e。核算与分析天津垃圾能源化的单位温室气体减排的成本效益，并对外部性内部化实现程度不同的各种情况进行了分析。结果发现支付的垃圾处理费看似是解决局地污染问题，实际影响到温室气体协同减排的效益。即使没有碳交易，随着地方政府支付给企业的垃圾处理费增加，同样也会提高单位温室气体减排的收益，从而促进减排。 Waste-to-energy can not only generate energy in the municipal solid waste disposal process, but also reduce greenhouse gas emission. Based on the greenhouse gas reduction of two waste-to-energy methods: incineration with energy (electricity and heat) and landfill with landfill gas utilization, this paper made a cost-benefit analysis of them. We identified and described private cost and environmental benefits of the two waste-to-energy projects. Taking Tianjin Binhai municipal solid waste incineration power generation CDM project and Tianjin Shuangkou landfill gas recovery and electricity generation CDM project as examples, the calculation method provided by Intergovernmental Panel on Climate Change Guidelines in 2006 was used for calculating greenhouse gas reduction. It can be calculated that dispos-ing of 1t municipal solid waste in the way of incineration with energy could reduce 0.777 tCO2e, and in the way of landfill with landfill gas utilization could reduce 0.657 tCO2e. Then we calculated the costs and benefits of waste-to- energy projects’ per unit greenhouse gas reduction and the internal rate of return of waste-to-energy projects, and made a cost-benefit analysis of them under different internalization of externalities realization situations. It seemed that the payment of waste disposal fees was to solve local pollution problems, but it actually impacted the benefits of greenhouse gas collaborative emission reduction. Even without carbon trading, as gate fees paid by local governments to waste-to- energy enterprise increasing, it would also improve the benefits of per unit greenhouse gas reduction, so as to promote the reduction.

Collaborative Emission Reduction of Greenhouse Gas Emissions and Municipal Solid Waste (msw) Management-Case Study of Tianjin

There is a huge potential for reducing greenhouse gas emissions in the way of disposing municipal solid waste (MSW), and the important role of MSW in global greenhouse gas emissions has attracted much attention. Based on the composition of Tianjin MSW and its content, collaborative emission reduction of three main MSW disposal ways were analysis, including landfill without landfill gas (LFG) utilization (S1), landfill with LFG utilization (S2), and incineration (S3). Taking Tianjin Binhai municipal solid waste incineration power generation CDM project and Tianjin Shuangkou landfill gas recovery and electricity generation CDM project as examples, the calculation methods provided by Intergovernmental Panel on Climate Change (IPCC) Guidelines were used to calculate the greenhouse gas emissions and emission reductions, and then compared the collaborative emission reductions of the three scenarios. Results show that collaborative emission reductions of S1∼S3 respectively are 0.602 tCO2e/t MSW, 0.657 tCO2e/t MSW, and 0.871 tCO2e/t MSW, so the results of the comparison is S3>S2>S1.
