The rapid development of mining activities has produced huge amounts of waste. This waste, found in abandoned mine sites, provides the potential opportunity of extracting raw material. The current study, therefore, focuses on testing the validation of a shared methodology to recover extractive waste from abandoned mines, and applies this methodology to a case study in Gorno, northwest Italy. The methods focused on: (1) analyzing the impact of tailings and fine fraction of waste rock (<2 mm) on plants (Cress - Lepidium Sativum) to assess usability of both as soil additive, and (2) recovering raw materials from tailings and coarse fraction (>2 mm) of waste rock, by means of dressing methods like wet shaking table and froth flotation.

These four alternative technologies were simulated using municipal-level data on food waste and manure in New Jersey. The criteria used to assess the four technologies include technological productivity, economic benefits, and impact on land scarcity. Anaerobic digestion with gas collection has the highest technological productivity; using anaerobic digesters would supply electricity to nearly ten thousand families in New Jersey. In terms of economic benefits, the landfill to gas method is the least costly method of treating waste. In comparison, direct combustion is by far the most costly method of all four waste-to-energy technologies. Keywords: Organic waste; manure; combustion; land-fill gas; aerobic composting; anaerobic digestion 1. Introduction Population growth and urbanization yield an increase in the generation and disposal of waste. On average, each person in the U.S. produces 1.5 kilograms of municipal solid waste (MSW) per day.

Current low recycling technology, high economic cost, and weak disposal capability make it difficult for e-waste to be rendered 100% harmless. E-waste disposal requires new site-selection methods and site-saving technology to take into account the loss of public perceived value. This study attempts to improve e-waste disposal through siting and landscaping to reduce perceived value loss. The first step is to determine the minimum distance for landfill siting by surveying the minimum loss of perceived value and to use the geographic information system (GIS) to sketch the suitable landfill site thereafter.

Generally, there is a large potential for circular economy in the city as the main proportion of the waste flows are recyclables. Due to the missing selective collection system, this potential is not used in the full extend yet, even if the collection of the entire waste volumes is envisaged in the National Waste Management Strategy by 2025.

At present, LFM remains as an emerging concept with a few pilot-scale project implementations, which presents challenges when assessing its economic performance. These challenges include large knowledge deficits about the individual processes along the LFM process chain, lack of know-how in terms of project implementation and economic drivers, and limited applicability of results to specific case studies. Based on how these challenges were addressed, this thesis aims to analyze the usefulness and validity of different economic assessments of LFM towards the provision of better support for decision-making and in-depth learning for the development of cost-efficient projects.

  • Landfill Reclamation
    United States Solid Waste EPA530-F-97-001 Environmental Protection and Emergency Response July 1997 Agency (5306W) 1EPA Landfill Reclamation his fact sheet describes new and innovative technologies and products that meet the performance standards of the Criteria for Municipal Solid T Waste Landfills (40 CFR Part 258). Landfill reclamation is a relatively new approach used to expand municipal solid waste (MSW) landfill capacity and avoid the high cost of acquiring addi- tional land. Reclamation costs are often offset by the sale or use of recovered materials, such as recyclables, soil, and waste, which can be burned as fuel. Other important benefits may include avoided liability through site remediation, reductions in closure costs, and reclamation of land for other uses. Despite its many benefits, some potential drawbacks exist to landfill reclama- tion. This technology may release methane and other gases, for example, that result from decomposing wastes. It may also unearth hazardous materials, which can be costly to manage. In addition, the excavation work involved in reclamation may cause adjacent landfill areas to sink or collapse. Finally, the dense, abrasive nature of reclaimed waste may shorten the life of excavation equipment. To identify potential problems, landfill operators considering recla- mation activities should conduct a site characterization study. Landfill reclamation projects have been successfully implemented at MSW facilities across the country since the 1980s. This fact sheet provides information on this technology and presents case studies of successful reclamation projects. The Reclamation Soil Separation (Screening) A trommel (i.e., a revolving cylindrical sieve) Process or vibrating screens separate soil (including Landfill reclamation is conducted in a num- the cover material) from solid waste in the ber of ways, with the specific approach based excavated material.
