This paper presents a new methodology called Waste And Source-matter ANalyses (WASAN) which helps a group to analyse waste-production and build actions to minimise avoidable waste. Designed for Licencees of nuclear facilities as Health and Safety Executive (HSE) Guidance on what constitutes good practice, WASAN uses lessons from Systems Thinking, Waste Management Hierarchy, Hazard Operability (HAZOP) Studies, As Low As Reasonably Practicable (ALARP), simulation modelling and sensitivity analysis. These lessons are used to support groups when developing plans to reduce avoidable waste production. We report on the development of WASAN and its use in three workshops. This paper reports progress on the development of waste management guidance for the HSE and does not currently represent its final regulatory view.

The study sought to assess the social context of solid waste disposal pattern of residents in Ibadan metropolis, in order to assess the Solid waste disposal patterns of people in Ibadan metropolis, Oyo State, Nigeria. Specifically, the study identified solid waste disposal habits of residents, frequency of clearing the dumpsters, accessibility of waste dumpsters to people determines the waste disposal pattern of people; and analyze the willingness of people in Ibadan to pay for improved service. Solid waste management has been part of human activities right from time. Efforts by Oyo State Government is seen in the collection of dirt that have been placed on the medians. Waste generation is an unavoidable product of man activities, however, sustainable management of such waste is a challenge faced in many countries today. Nigeria, a developing country in Africa, has been in a quandary of how to efficiently manage the municipal solid waste its population generates. Many states in the country lack adequate plans and infrastructure required for efficient and sustainable management of municipal solid waste. For Ibadan, the largest city in Nigeria, the problem is further compounded by its rather large and still increasing population. In this research, Ibadan metropolis is taken as a case study; the rate of solid waste handling in households as regards solid waste management from household collection to final disposal are focused upon. The study found out that 45.6% drop their refuse in the dumpsters as 18.8% burns their refuse, 17.7% of the respondents drops their waste on the median, 12% in the drainage while 6% opts to drop their waste in the streams. On the effectiveness of the Private operators collecting waste from the respondents, the study found out that 7.6% effective, 37.5% of the respondents says the operators waste collection is poor, 7% says it is abysmal while 43.5% said it is not applicable to them because they do not have storage containers in their houses and as a result did not subscribe to their service. Many countries, particularly the developed ones, have employed options in the waste management hierarchy for sustainable management of their municipal solid waste and the blend of options employed is usually highly dependent on local factors. Following the waste management hierarchy, possible options for sustainable municipal solid waste management in Ibadan are discussed. It is concluded that waste reduction, reuse, and recycling are potential management options for the state. Landfilling will remain an important option for final disposal but reliance on this method could be significantly reduced if management options are exploited to the maximum in a sustainable solid waste management structure in Ibadan metropolis.

The U.S

According to the waste management hierarchy published by the U.S. EPA, waste reduction and reuse are the most preferred modes of waste management, followed by recycling, energy recovery and lastly disposal. As many communities in the U.S. work towards sustainable waste management practices, recycling tends to be a cost-effective and common solution for handling municipal solid waste. With the introduction of single-stream recycling and automated materials recovery facilities (MRFs), where commingled recyclables are sorted into various commodity streams for sale to recycling facilities, recycling rates have steadily climbed in recent years. Despite increasing total recycling rates, contamination and diminishing returns for higher recovery ratios causes MRFs to landfill 5–25% of the incoming recycling stream as residue. This residue stream is composed primarily of plastics and fiber, both of which have high energy content that could be recovered instead of buried in a landfill. Plastics in particular are reported to have heat contents similar to fossil fuels, making energy recovery a viable end-of-life pathway. Sorting, shredding and densifying the residue stream to form solid recovered fuel (SRF) pellets for use as an alternative fuel yields energy recovery, displaced fossil fuels and landfill avoidance, moving more disposed refuse up the waste management hierarchy. Previous studies have shown that plastic, paper, and plastic-paper mixes are well suited for conversion to SRF and combustion for energy production. However, these studies focused on relatively homogenous and predictable material streams. MRF residue is not homogenous and has only a moderate degree of predictability, and thus poses several technical challenges for conversion to SRF and for straightforward energy and emissions analysis. This research seeks to understand the energetic and environmental tradeoffs associated with converting MRF residue into SRF for co-firing in pulverized coal power plants. A technical analysis is presented that compares a residue-to-SRF scenario to a residue-to-landfill scenario to estimate non-obvious energy and emissions tradeoffs associated with this alternative end-of-life scenario for MRF residue. Sensitivity to key assumptions was analyzed by considering facility proximity, landfill gas capture efficiency, conversion ratio of residue to SRF and the mass of residue used. The results of this study indicate that the use of MRF residue derived SRF in coal fired steam-electricity power plants realizes meaningful reductions of emissions, primary energy consumption, coal use and landfill deposition.

Construction and demolition waste are the major issue as a direct consequence of increased global urbanization. It impacts the environmental efficiency of the construction industry, contributing to 35% of the global landfill. This research considers the two main fundamental factors affecting the demolished building waste management, which are the management hierarchy including the 3R strategies and the project life cycle and management tools. The inappropriate treatment and disposal of Construction and demolition waste give rise to the environmental pollution, land price, and natural resource consumption. This paper scrutinizes the concept of Construction and demolition waste management and review the extant studies in the managerial areas of Construction and demolition waste. These findings are aimed at clarifying the current and future practices of Construction and demolition waste management practices with an understanding for the sustainable governance. Keywords: Construction and demolition waste, management, review.

The article analyzes the legal regulation of hazardous waste management in Lithuania and its compliance with regional waste management strategies and legislation. Noteworthy, that in Lithuania, the hazardous waste management policy is based on the EU waste management hierarchy. We can assume that the system of administrative measures applied for the management of hazardous waste: licensing, permits, is appropriate and presupposes the reduction of the negative impact of the generation and management of hazardous waste on human health and the environment. For companies, which operates with hazardous waste management the legislation imposes an obligation to operate in accordance with the general EU environmental principles of precaution and sustainability, technical feasibility and economic viability, protection of resources, and the overall impact on the environment, public health, the economy and the social environment.

The waste management strategies released and applied in EU countries endeavor to achieve the improvement of natural resources use and efficiency towards reducing the air, water and soil pollution due to improper waste disposal or treatment. This paper is a blueprint on waste generation and waste management Policies, Laws and strategies existing in Romania compared to EU countries. According to Directive 2008/98/EC Waste, is defined as “any substance or object which the holder discards or intends or is required to discard”. One of the main principles of waste management strategies is to be able to process the waste generated towards reaching as up as possible the Waste Management Hierarchy. From the circular economy concept point of view, the incorrect treatment of waste is representing an important loss of resources, both in raw materials and energy and therefore recycling and reuse should reach a superior level every year.

Legislative Measures

At European level, there are concrete measures regarding waste management in the circular economy, and these refer to: mandatory recycling rates for different categories of waste: plastics, glass, metals, paper and cardboard as well as biodegradable waste; the obligation to redesign the products in order to increase the proportion of raw materials resulting from recycling and to increase the degree of recycling of products, in order to consider them as secondary raw materials; promoting and stimulating the reuse of products; increasing the recycling rate of municipal waste by 2030 to a minimum of 65%; increasing the recycling rate of packaging waste by 2030 to a minimum of 75%; reduction of food wastage and implicitly of the resulted food waste by 50% by 2030. The large amount of packaging waste determined the taking of legislative measures that defined the obligations of pack- aging producers/distributors, recycling objectives and the waste management hierarchy. New targets for the recycling of packaging waste predict a growth to 65% in 2025 and 70% in 2030 [1]. Textile packaging waste is an important link in the integrated management of waste whose recovery contributes to the conservation and improvement of natural capital.
