Economic feasibility and environmental impact analysis of landfill gas to energy technology in African urban areas

Journal of Cleaner Production, 2021
Landfilling is one of the cheapest methods of municipal solid waste disposal worldwide, especially in developing countries. Disposal of municipal solid waste in landfills produce greenhouse gases, such as methane and carbon dioxide, which, if not managed

A review on landfill system for municipal solid wastes: Insight into leachate, gas emissions, environmental and economic analysis.

Chemosphere, 2022
Landfill is one of the common processes for removing and disposing waste materials that comprises the final method of disposing municipal solid waste. Disposal of municipal solid waste through land filling has become an important environmental problem ...

Enhancement of landfill gas generation from aged waste by a combination of moisture adjustment and application of biochar and neutral red additives: A field-scale study

, 2021
Many landfills suffer from a sharp drop in landfill gas generation after an initial period of gas generation. A field-scale study was conducted to investigate the effects of moisture adjustment using stormwater and compost leachate, and additives ...

Modelling gas generation for landfill

Environmental Technology, 2016
A methodology was developed to predict the optimum long-term spatial and temporal generation of landfill gases such as methane, carbon dioxide, ammonia, and hydrogen sulphide on post-closure landfill. The model incorporated the chemical and the biochemical processes responsible for the degradation of the municipal solid waste.

Numerical simulation of landfill gas pressure distribution in landfills

Waste Management & Research: The Journal for a Sustainable Circular Economy, 2013
Landfill gas emissions are recognized as one of the three major concerns in municipal solid waste landfills. There are many factors that affect the generation of landfill gas when the landfill is capped. In this article, a model has been developed based on the theory of porous media flow.

Treatment of Landfill Leachate by Irrigation and Interaction with Landfill Gas

Environmental Technology, 2006
The treatment efficiency of landfill leachate irrigation and the effect of landfill gas addition were investigated in a vegetated compost/gravel substrate by monitoring soil moisture content, drainage water volume and quality in a two years lysimeter experiment.

Quantification of landfill gas generation and energy recovery estimation from the municipal solid waste landfill sites of Delhi, India

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2020
In this study, estimation of landfill gas (LFG) emission from three existing landfill sites of Delhi such as Ghazipur, Bhalswa, and Okhla was carried out using three LFG generation models, namely, IPCC Default model, First order decay model, and LandGEM.

Landfill Gas: A Major Pathway for Neutral Per- and Polyfluoroalkyl Substance (PFAS) Release

Environmental Science & Technology Letters
: The undisclosed and ubiquitous use of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in consumer products has led to a growing issue of environmental pollution, particularly within the solid waste community, where the fate of volatile (neutral ...
