This paper presents an approach for determining the economic feasibility of refuse-derived fuel production and the recovery of various materials. The information presented here is based largely upon data developed for [1] the metropolitan Washington, D. C. area1 as input for the consideration of a regional resource recovery program which would eventually encompass some 4000 t per day (3628.8 Mg per day) of municipal solid waste. The initial facility would process 650 t per day (589.7 Mg per day). The facility is designed to recover refuse-derived fuel (RDF), light and heavy ferrous metals, aluminum and other nonferrous metals, flint glass cutlet, color-mixed glass cullet, color-mixed glass fines, and handpicked waste newspapers and corrugated. For the most part, advance commitments for the sale of these products have been obtained. An early stage in the planning process requires recovery product revenues to be estimated and the feasibility of the process to be analyzed. Since materials revenues can be predicted with a higher degree of certainty than RDF revenues, it becomes necessary to determine what revenues will be required from the sale of the RDF in order that projected economics can at least be the same as the alternative disposal practice. A technique is described here which will assist the decisionmaker to evaluate the economic feasibilty of the proposed project by determining what is termed here the RDF “Indifference Value [3].”

AbstractThe authors determined the morphological composition of refuse derived fuel (RDF) produced in Latvia and Lithuania by manually sorting. The parameters of RDF (moisture, net calorific value, ash content, carbon, nitrogen, hydrogen, sulphur, chlorine, metals) was determined using the EN standards. Comparing obtained results with data from literature, authors have found that the content of plastic is higher but paper and cardboard is lower than typical values. Results also show that the mean parameters for RDF can be classified with the class codes: Net heating value (3); chlorine (3); mercury (1), and responds to limits stated for 3rd class of solid recovered fuel. It is recommended to separate biological waste at source to lower moisture and ash content and increase heating value for potential fuel production from waste.

The City of Ames, IA (City) processes 220 tons per day of municipal solid waste (MSW) at their Arnold O. Chantland Resource Recovery System (RRS). This facility is depicted in Figure 1. The objectives of this facility have both an economic and an environmental component: to reduce the amount of MSW that is otherwise disposed in their local landfill, thereby increasing the life of the landfill; and produce refuse-derived fuel (RDF) to reduce the amount of coal consumed at the City’s municipal electrical generating station. [Note: Approximately 70% of the MSW is converted into RDF, comprising 10 to 20% of the feedstock to the generating station.]

The quantity of biodegradable plastics is increasing steadily and taking a larger share in the residual waste stream. As the calorific value of biodegradable plastic is almost two-fold lower than that of conventional ones, its increasing quantity decreases the overall calorific value of municipal solid waste and refuse-derived fuel which is used as feedstock for cement and incineration plants. For that reason, in this work, the torrefaction of biodegradable waste, polylactic acid (PLA), and paper was performed for carbonized solid fuel (CSF) production. In this work, we determined the process yields, fuel properties, process kinetics, theoretical energy, and mass balance. We show that the calorific value of PLA cannot be improved by torrefaction, and that the process cannot be self-sufficient, while the calorific value of paper can be improved up to 10% by the same process. Moreover, the thermogravimetric analysis revealed that PLA decomposes in one stage at ~290–400 °C with a maximum peak at 367 °C, following a 0.42 reaction order with the activation energy of 160.05 kJ·(mol·K)−1.

AbstractThe management of municipal solid waste is a major logistic and environmental problem worldwide. Nonetheless, the organic fraction of municipal solid waste (OFMSW) is a valuable source of nutrients which can be used for a variety of purposes, according to the Circular Economy paradigm. Among the possible applications, the bioproduction of a biodegradable polyester, poly(3-hydroxybutyrate) [P(3HB)], using OFMSW as carbon platform is a promising strategy. Here, an economic and environmental assessment of bacterial P(3HB) production from OFMSW is presented based on previously published results. The SuperPro Designer® software was used to simulate P(3HB) production under our experimental parameters. Two scenarios were proposed depending on the fermentation medium: (1) enzymatic hydrolysate of OFMSW supplemented with glucose and plum waste juice; and (2) basal medium supplemented with glucose and plum waste juice. According to our results, both scenarios are not economically feasible under our experimental parameters. In Scenario 1, the low fermentation yield, the cost of the enzymes, the labour cost and the energy consumption are the factors that most contribute to that result. In Scenario 2, the cost of the extraction solvent and the low fermentation yield are the most limiting factors. The possibility of using process waste as raw material for the generation of other products must be investigated to enhance economic feasibility. From an environmental viewpoint, the photochemical oxidation potential (derived from the use of anisole as extraction solvent) and the generation of acid rain and global warming effect (caused by the burning of fuels for power generation) are the most relevant impacts associated to P(3HB) production under our experimental parameters.
