Buildings generate a significant amount of waste that has considerable impacts on environment and energy flow. This study aims to investigate the waste capacity of the selected district and its effect on the environment within the current waste management policy via Life Cycle Assessment (LCA)...

Biogas systems from solid waste landfill and their pipeline network have been constructed with a total biogas capacity of 1000 m3/day in two villages in Bantan subdistrict in northern Thailand. Two hundred households in two villages receive the benefits from biogas technology in many ways. It...

Thermo-electric generators (TEGs) have been identified as promising solid-state devices to recover exhaust waste in internal combustion engines (ICEs). As the TEGs are able to convert heat directly into electricity, they can be used to down size the alternator of the ICEs. However, the addition...

Food production is a complex process where uncertainty is very relevant (e.g. stochastic yield and demand, variability in raw materials and ingredients…), resulting in differences between planned production and actual output. These discrepancies have an economic cost for the company (e.g....

The constant increase of municipal solid wastes (MSW) as well as their daily management pose a major challenge to European countries. A significant percentage of MSW originates from household activities. In this study we calculate the costs of setting up and running a zero-waste mortar-producing...

The objective of this paper is to optimise the liquid product of pyrolysis from as much as 500 g of polypropylene (PP) plastic waste, using a fixed bed type reactor in a vacuum condition (-3 mm H2O), to minimise the oxygen entering the reactor. The vapour flows through the 4-tray distillation...

In this study, attempt was made to estimate the quantity of municipal solid waste (MSW) generated per annum, the generation rate in kg/capita/day as well as the quantity and the fractions of the waste streams available for energy production. The physical characterization of the waste streams...

Household waste management is one of the major challenges of municipalities in developing countries. In many large cities, private service providers deliver the service of household waste collection for a fee, but in smaller cities this service is not always available as it may not be profitable...

Purpose - The key challenge that urban cities in most developing and transitional economies is confronting is municipal solid waste (MSW) management. Waste separation is a critical component to successful recycling management in terms of enhancing the quality of recyclables, reducing MSW and...

Worldwide legislation requires the presence of air filtration systems with detectors to monitor and control the release of radionuclides into the air in nuclear medicine centers. Dealing with radionuclides includes trapping the vapors and storing it for decay. However, these methods can involve...

Open dumping of waste and discharging untreated wastewater into environment are key causes of environmental pollution in the developing world, including South Asian countries. Waste and wastewater however can be a source for recovering energy, nutrients and water if properly treated or recycled...

The collection of solid waste and the recovery of recyclable material from waste belong to the many challenges Cuba has been facing over the past years. In this paper, we give a short account of the actual waste situation and analyze the causes of the obvious deficiencies of the waste sector. We...

To internalize pollution externalities into household waste generation, Unit Pricing Systems (UPS) have been adopted worldwide. This paper evaluates the causal effects of a UPS on the disposal of municipal solid waste in Trento, Italy. To account for policy endogeneity due to unobservables, we...

Properly managed sanitation systems and improved wastewater treatment are important for safeguarding environment and enhancing sustainable livelihoods in vast areas of South and Southeast Asian countries. Recovering nutrients and energy from organic waste and wastewater is an effective option...

The work attempts to comprehend why littering is so extensive and, with the use of several findings provided in Gary S. Becker's article entitled “Crime and Punishment: An Economic Approach”, to explain why under current conditions more waste discarded in the environment can be expected. The...

Due to the positive effect it has on the environment, while also creating social and economic value, recycling represents a key factor in the realization of a circular economy and of sustainable development. For the implementation of efficient programs, the recycling rate has become a relevant...

The number of recent publications on food loss and waste, and policy initiatives of governments and international organizations indicate the high priority of this topic. With this in mind, the methodology to measure food loss and waste has important implications for policy recommendations. The...

We live in the plastic age (the "plasticene"), producing over 300 million tonnes (mt) of plastic every year globally, 5–15 mt of which flow into already polluted oceans. Plastic remains a key material in the global economy, but low rates of collection, reuse and recycling, emissions of...

This study analyses the environmental and financial sustainability of solid waste management in Indian cities. It presents an assessment of the rapidly rising volume of municipal solid waste, its changing composition, the continuing practice of mixing biodegradable (wet) waste with dry waste at...

"Food loss is a serious issue in the United States. It affects all aspects of the supply chain, from farmers to consumers. While much is already known about loss at the consumer level, our understanding of the amount of food that never makes it to this stage is more limited. The Economics of...

Gebührensteigerungen und vor allem -differenzen bei der kommunalen Hausmüllentsorgung stehen seit mehreren Jahren im Fokus des öffentlichen Interesses. Die Bürger können die immensen Gebührenunterschiede bei gleichen Entsorgungsleistungen nicht nachvollziehen. Die Kommunen führen die...

Mismanagement of waste and wastewater is a key reason behind the continuing environmental pollution and degrading livelihoods across the developing countries of South Asia such as Sri Lanka. Recovering nutrients and energy from waste and wastewater streams can not only address the challenging...

The feasibility of using finned oscillating heat pipes (OHPs) for heat exchange between counter-flowing air streams in HVAC air systems (i.e., outdoor and exhaust air flows), along with the associated cost savings in typical North American climates, is investigated. For a prescribed temperature...

An app to evaluate the Street Cleanliness and Waste Collection Service was developed. This app is based on a Plan of Indicators that can be used to evaluate the Street Cleanliness and Waste Collection Service of Santander municipality. Specific methodologies for calculating and evaluating 59...

This paper sheds light on the increase in generation of non-metallic mineral wastes and the decrease in demand for construction by investigating the material flow resulting from and the economic influence of changes in the supply and demand for wastes, focusing on the period from the near future...

Since the 2003 launch of the Visit Japan Campaign by Tourism Agency, the number of foreign visitors to this nation has climbed significantly, reaching 19.7 million people in 2015, a number 3.8 higher than 2003. The increase in tourists from China, Taiwan, and Korea was especially significant,...

The paper presents a novel method of rational management of solid waste, namely an example of a modern landfill with enhanced leachate recirculation – a bioreactor landfill. The aim of the paper was to compare modern solutions concerning waste storage with traditional methods in terms of...
