Disposal options for solid waste of Bangalore city based on its characteristics
A detailed analysis of Bangalore's solid waste has been done to suggest various management options for safe disposal. It has been observed that Bangalore's solid waste contains a larger proportion of degradable waste compared to many other cities. Based on detailed analysis of available data, it has been suggested that a landfill with a leachate and gas collection system is better than an inert ...

Shredder Machine for Municipal Solid Waste
If you need to deal with municipal solid waste, then you need an industrial shredder (usually dual-shaft shredder), which is used to shred the mixed waste stream into small pieces for subsequent processing. There are many treatment methods for municipal solid waste, usually bio-mechanical treatment or mechanical treatment, organic matter is fermented, combustible waste is made into RDF, and metal ...

Compatibility of compacted lateritic soil treated with bagasse ash and Municipal Solid Waste leachate
Compatibility tests were carried out on lateritic soil treated with up to 12% bagasse ash compacted at about 2% wet of their respective optimum moistures using the standard Proctor energy. Samples were sequentially permeated with distilled water and municipal solid waste (MSW) leachate for 22 and 69 days, respectively, until steady flows were established. The final hydraulic conductivity values ...

GIS-based modelling for the estimation of municipal solid waste generation and collection
In the present paper, an innovative model for the estimation of municipal solid waste generation and collection is proposed. This model is part of an extended solid waste management system and uses a spatial Geodatabase, integrated in a GIS environment. It takes into consideration several parameters of waste generation, such as population density, commercial activities, road characteristics and ...

Assessment of recycling potential of municipal solid waste in Mauritius
The purpose of this paper is to implement a Reverse Vending Machine (RVM) which would divert valuable resources to recycling centres. It assessed materials having attractive scrap values such as glass, PET bottles and Used Beverages Cans (UBC). In this paper, two scenarios were proposed, namely: Scenario 1 which dealt with the selling of recyclables to recycling plants and Scenario 2 which ...

Release behaviour of chromium from ferrochrome slag
Huge amount of ferrochrome slag, a solid waste is being generated from submerged electric arc furnace during manufacturing of ferrochrome alloy. The waste slag contains about 6–12% chromium as chromium oxide and it has the potentiality of releasing hazardous chromium compounds. Although chromium exists in the slag as highly immobile Cr (III) state, there is possibility of chromium release under ...

E-waste vis-à-vis human health and environment
The social, economic and technological growth of a developing society has resulted in rapid product obsolescence which in turn has become a new environmental challenge – i.e., ‘electronics waste’ (e-waste). Electronic waste has not been a problem as long as there were a few computers or other electronic devices on earth. With the increasing use of computers/electronic devices, our planet has ...

Innovative fracture-resistant construction material from C&D waste aggregate, fly ash and recycled plastics
A laboratory investigation was conducted to evaluate the fracture behaviour of an alternative pavement foundation material containing cement stabilised reclaimed crushed aggregate, Class C fly ash and waste-plastic strip (high density polyethylene or HDPE) reinforcement. The primary objective of using strip reinforcement was to improve the tensile strength, crack resistance and toughness ...

Leachate Endanger Our Life
Leachate is toxic wastewater with a high concentration of COD, BOD, NH -N that results from solid waste handling processes, such as landfills, incineration plants and waste transfer stations. Containing inorganic and organic chemicals, heavy metals and pathogens, it has the potential to pollute groundwater, posing a significant risk to the environment and public health. Given its complex and ...

Leachate Treatment
We pride ourselves in our membrane technology that effectively and reliably yields clean, reusable water. Our drive and dedication to clean industrial solutions has made us a top competitor in the industry, allowing us to apply our membrane technologies to many different fields. A typical sanitary landfill site When solid waste degrades and is soaked in precipitation, a black liquid called ...

Oil waste management through large scale landfarming: a case study
The operational activities of the oil industry generate solid waste containing several classes of hydrocarbons. Landfarming enables the treatment of large amounts of oil waste through the disposal of waste in the reactive soil layer and hydrocarbon biodegradation. The aim of the present study was to evaluate oil waste management in a 1,000 m² of landfarming area. The operational method used in ...

Incorporation of petroleum waste in clay ceramics and its characterisation
In Brazil, the growth of the petroleum industry has resulted in an increasing amount of toxic oily wastes that have a high environmental impact. This work analyses the possibility of recovering waste from the petroleum industry using the powder technology route to produce clay-based ceramics. Batches of clay-petroleum waste mixes with up to 20 wt.% waste were prepared. The results showed that the ...

Recovery Rates From Recycling
Introduction Recycling waste material resides at the heart of achieving the objective of sustainable solid waste management. When complemented with the other two pillars of the 3R strategy, i.e., reduce and reuse, recovery rates from recycling can significantly be improved. Higher recovery rates from recycling can significantly reduce the amounts of material requiring the final treatment and ...

Temperature–dependent polylactic acid (PLA) anaerobic biodegradability
Polylactic acid (PLA) biodegradability is mostly claimed according to PLA biodegradation behaviour under aerobic composting conditions. However, waste materials containing PLA are frequently disposed of in municipal landfills, which are operated anaerobically. PLA anaerobic sludge digestion results are acquired to elucidate effects of the degrading temperature on PLA biodegradation. When the ...
