“…It is also seen as the most natural way of recycling through biological reactions to achieve environmental self-cleaning among the various disposal options [41,42]. However, the cost of organic fertilizer composted from food waste still lacks competitiveness with respect to chemical fertilizers.…”

Abstract:The purpose of this paper is to compare the recycling performance for some waste fractions selected including food waste, bulk waste, paper, metal products, plastics/rubber and glass products and then to develop some directions for the future improvements. The priority of each waste fraction for recycling is also analyzed by using an importance-performance analysis. Traditionally, the recycling rate that is calculated by the ratio of waste recycled to waste collected is used as an indicator to measure recycling performance. Due to a large variation among waste fractions in municipal solid waste (MSW), the recycling rate cannot reflect the actual recycling performance. The ceiling of recycling rate for each waste fraction estimated from the diffusion models is incorporated into a model to calculate recycling performance. The results show that (1) the diffusion effect exists significantly for the recycling of most recyclables but no evidence is found to support the diffusion effect for the recycling of food waste and bulk waste; (2) the recycling performance of waste metal products ranks the top, compared to waste paper, waste glass and other waste fractions; (3) furthermore, an importance-performance analysis (IPA) is employed to analyze the priority of recycling programs and thus this paper suggests that the recycling of food waste should be seen as the most priority item to recycle.

“…This is a similar CAPEX to the 4 MWe turnkey RDF solution from Chamco [43], which presents a cost of 3977 €/kWe (less 6.6% than the 4 MWe cost model used). In addition, the RDF selection and treatment (eventual pelletizing) represents a cost for the power plant (10-21 €/ton of RDF [44]), depending on the process configuration and MSW composition. Annual O&M costs differ significantly from different references: for similar Termiska Processer power plant technology applied to the Chianti power plant but with larger power (75 MWe) O&M are 21% of the CAPEX, with waste disposal cost included in the O&M cost [42]; for the Chamco solution the O&M are estimated slightly above 13% of CAPEX per year [43]; a different study from Klein [45] pre sents an annual O&M cost for RDF gasification power plants from 9 to 20 % of CAPEX, including a 38 €/ton ash disposal cost.…”

Biomass and central receiver system (CRS) hybridization: Integration of syngas/biogas on the atmospheric air volumetric CRS heat recovery steam generator duct burner

et al. 2015

Central receiver systems (CRS) are a promising concentrated solar power (CSP) technology for dis-patchable electricity generation. The CRS levelized cost of electricity (LCOE) is usually increased by low power-block capacity factors or by high thermal storage costs. The economical turnover is still positive for the Portuguese case but depends on the bonus feedin tariffs. On the other hand, with biomass existing feed-in tariffs and raising prices, the viability of current biomass power plants is at risk. To address these issues, several base case power plants and hybrid biomass/CSP options are analyzed: wood gasification, refusederived fuel pellets, biogas from a wastewater anaerobic digester, biogas from a landfill and natural gas.The solution with lower LCOE was obtained for the hybridization of a 4 MWe CRS using an atmospheric volumetric receiver with biogas from an anaerobic digester using sludge from a wastewater treatment plant (WWTP). Different results would be obtained for the hybrid systems if different CRS technologies are used. The hybrid CRS/anaerobic digester power plant LCOE is 0.15 €/kWh, returning the investment in 13 years (assuming sludge collection and transport without cost) with the best net present value (15 million euro) and internal rate of return of all the hybrid options.

International Best Practices for Pre-Processing and Co-Processing Municipal Solid Waste and Sewage Sludge in the Cement Industry

Co-processing municipal solid waste (MSW) and sewage sludge in cement kilns can both reduce the cement industry's growing fossil fuel use and carbon dioxide (CO 2 ) emissions and help address the increasing need for safe and environmentally sensitive municipal waste treatment and disposal.The cement industry accounts for approximately 5 percent of current anthropogenic CO 2 emissions worldwide. Given increasing cement demand and production, the industry's absolute energy use and CO 2 emissions will continue to grow. Cement kilns typically burn fossil fuels, which are nonrenewable and being depleted rapidly. Treating wastes in cement kilns, known as co-processing, can reduce the industry's reliance on fossil fuels and decrease associated CO 2 emissions. The ashes from waste co-processing will be integrated into the clinker which can result in saving the virgin raw materials. In addition, treating wastes in cement production can help alleviate the problems associated with the increase in waste generation around the world, especially in developing countries experiencing rapid urbanization. Municipalities and governments in many urban areas, especially those with underdeveloped waste management systems, face growing difficulties disposing of MSW and sewage sludge in a manner that protects human and environmental health.The high temperatures and sufficiently long residence time in cement kilns and other characteristics of cement production make co-processing of waste materials a viable strategy. Wastes have been co-processed in cement kilns for more than 20 years, and this practice is prevalent in some developed countries such as the United States and Japan, as well as in a number of countries in the European Union. Many developing countries such as China and nations in Southeast Asia are initiating programs to promote co-processing of wastes in the cement industry. Regulations, standards, and the technical infrastructure in these developing countries are less mature than in countries that have a long experience with co-processing waste in the cement industry.
