Assessment of the Possible Reuse of Extractive Waste Coming from Abandoned Mine Sites: Case Study in Gorno, Italy

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. -
Numerical Model of Leachate Recirculation in Bioreactor Landfills
water Article Numerical Model of Leachate Recirculation in Bioreactor Landfills with High Kitchen Waste Content Peng Zhang , Hailong Liu * , Xingyao Jiang, Hao Lv, Chunyi Cui and Zhen Huyan Department of Civil Engineering, Dalian Maritime University, Dalian 116026, China; [email protected] (P.Z.); [email protected] (X.J.); [email protected] (H.L.); [email protected] (C.C.); [email protected] (Z.H.) * Correspondence: [email protected] Abstract: Surface spraying, horizontal trenches, and vertical wells are the most common leachate recirculation system used at landfills in engineering practice. In order to quantify the efficiency of the three aforementioned recirculation systems, a hydro–biochem–mechanical-coupled model was developed in the present work, which can describe hydrodynamic and biochemical behaviors in food-waste-rich landfills. A typical landfill cell was modeled in COMSOL. The results indicate that leachate recirculation can accelerate the decomposition of municipal solid waste (MSW) with food- rich waste content, relieving acidification, improving gas generation efficiency, and consequently, increasing the early settlement in landfills. Keywords: municipal solid waste; landfill; leachate treatment; coupled model; numerical simulation Citation: Zhang, P.; Liu, H.; Jiang, X.; 1. Introduction Lv, H.; Cui, C.; Huyan, Z. Numerical Disposing of municipal solid waste (MSW) has been a worldwide environmental Model of Leachate Recirculation in issue for decades.

Bioreactor Landfills: Experimental and Field Results
Waste Management 22 (2002) 7–17 www.elsevier.nl/locate/wasman Bioreactor landfills: experimental and field results Mostafa Warith Ryerson Polytechnic University, 350 Victoria Street, Toronto, Ontario, Canada M5B 2K3 Received 8 August 2000; received in revised form 29 January 2001; accepted 31 January 2001 Abstract Bioreactor landfills allow a more active landfill management that recognizes the biological, chemical and physical processes involved in a landfill environment. This paper presents the results of an experimental study carried out to determine the effect of solid waste size, leachate recirculation and nutrient balance on the rate of municipal solid waste (MSW) biodegradation. Higher rates of MSW biodegradation eventually cause a reduction of the contaminant life span of the landfill and decrease in the cost of long term monitoring. The study indicated that the smaller the size of the MSW the faster the biodegradation rate of the waste. In addition, the paper presents the results of leachate recirculation on solid waste biodegradation in a full-scale landfill site, which is located in Nepean, Ontario, Canada. The leachate was recirculated into the landfilled solid waste for 8 years through infiltration lagoons. Similar results to those obtained in the laboratory scale experiments were noted. The average pH of the leachate in the early stages of recirculation was on the acidic range of the pH scale, however, the pH value was in the range of 7–8 after 2 years of leachate recirculation. The concentration of chloride remained fairly constant at about 1000 mg/l during the leachate recirculation period. A decreasing trend of the organic load, measured as biological oxygen demand and chemical oxygen demand, was observed. -

Gottlieb 1, Fuqing Xu 2 and Yebo Li 2 1 Rutgers University, New Brunswick, NJ 08901, USA 2 The Ohio State University, Ohio 44691 * Correspondence: [email protected]; Tel: +1-848-932-9142 Abstract: This paper evaluates the benefits of converting food waste and manure to biogas and/or fertilizer, while focusing on four available waste treatment technologies: direct combustion, landfilling, composting, and anaerobic digestion. 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. -
