Multiple regression analysis for the estimation of energy content of municipal solid waste
A regression equation is proposed to predict the Higher Heating Value (HHV) of Municipal Solid Waste (MSW) from the waste data of 86 cities of 35 countries. A mathematical model is developed, by using Statistical Package for Social Sciences (SPSS-10.0), to correlate the energy content of waste with the variables derived from its physical composition. Performance of the proposed multiple ...

Modeling the household water consumption and solid waste generation in urban areas of developing countries by means of socioeconomic variables
The paper proposes two predictive models for water consumption and solid waste generation based on socioeconomic variables. These models were developed based on socioeconomic, water consumption and solid waste generation data from Belo Horizonte and validated for the city of Porto Alegre, confirming the intrinsic correlation between per capita income and the above mentioned features. The low ...

Waste quantification models for estimation of construction and demolition waste generation: a review
Quantification is crucial for construction and demolition waste management. Accurate estimation can be satisfied by developing waste quantification model that is applicable for regional or nation–wide C&D waste generation. This paper presents a review on quantification models for C&D waste from literatures and how they correlate. Most studies combine the empirical waste assessment data or waste ...

Optimisation of solid waste collection routes using Premium Solver Platform
This study illustrates the application of Premium Solver Platform software to optimise tours for the collection of municipal solid waste. Data required for optimisation was obtained from the municipal solid waste management authority, field studies and digitised map of a study area. Thereafter the optimisation problem was formulated as a travelling salesman problem (TSP) on Microsoft Excel ...

Providing laboratory results to Risk Assessors from ESdat
Risk Assessors often have very specific data layout preferences which is quite different to other staff. Many will use ESdat themselves in order to filter for specific datasets; others prefer to be provided with only a spreadsheet. In either case it is critical that time now be wasted re-formatting data when that can be avoided. Generally, Risk Assessors prefer one of the following to styles ...

Describing variability of MSW composition data with the log-logistic distribution
Variations in solid waste composition data are necessary as inputs to solid waste planning, yet uncertainty exists regarding which probability distributions might be generally valuable to describe the variability. Twenty-two detailed analyses of solid waste from British Columbia, Canada, were fitted to distributions using the BestFit software. Alternative distributions were ranked based on three ...

Too much trust in (social) trust? The importance of epistemic concerns and perceived antagonism
Social trust has often been claimed to be an important determinant of perceived risk, a finding that, if true, has important consequences for risk communication. However, the empirical basis of the alleged relationship between social trust and risk perception is weak. Previous work has pointed to other facets of trust as being more important: trust in science and technology per se (epistemic ...

Integrated system for regulatory control of the radioactive waste management in radioactive installations
The object of this paper is to present the 'Integrated Information System for Supporting the Inventory Control of Radioactive Waste' ? SICORR. The SICORR model considers the following items: the radioactive waste control inventory, encompassing the treatment and integration of the radioactive waste and the radionuclide data and processes; the installations that produce, use, transport or store ...

Future Waste Amounts in the EU
Abstract As waste generation and economic activity are closely related, it is possible to predict how much waste we will generate in years to come. Such projections are, however, subject to much uncertainty, especially because the necessary basis in the form of data on waste is, at the EU level, incomplete and lacks harmonisation. Nevertheless, the ETC/W has made such projections for household ...

Municipal solid waste: how to reduce it by 2050
The recent publication More Growth, Less Garbage (1) updates the data of the study What a Waste 2.0: A Global Snapshot of Solid Waste Management to 2050 (2), developed by the World Bank, which globally aggregates municipal solid waste national data, reporting estimated generation to 2050. Global waste generation is estimated to grow from 2.24 billion tonnes in 2020 to 3.88 billion tonnes in ...

To Compete or not Compete: Looking at Competition vs. Monopoly in EPR schemes
Across the world PRO organisations are available for companies to join in order to comply with their Extended Producer Responsibility reporting. Compliance schemes are membership organisations that register members with the relevant authority and ensure that companies meet their financial obligations under the different EPR directives. Some countries have a monopoly compliance scheme and others ...

What a waste: solid waste management in Asia
As urbanisation and economic development increases in Asia, nowhere is the impact more obvious than in society’s “detritus” or solid waste. Today, the urban areas of Asia produce about 760,000 tonnes of municipal solid waste (MSW) per day, or approximately 2.7 million m3 per day. In 2025, this figure will increase to 1.8 million tonnes of waste per day, or 5.2 million m3 per day. These estimates ...

A statistical approach to predict waste generation rates to support recycling programmes
Construction wastes constitute material with high potential for on-site reuse and off-site recycling; however, a significant fraction of this waste is still directed to landfills. Inability to predict time-dependent and activity-specific waste generation rates is one of the barriers to successful implementation of a construction waste minimisation programme. This paper discusses the development ...

An ontological approach to knowledge management for sustainable nuclear decommissioning
Nuclear decommissioning design and operational knowledge may remain relevant over many decades. Designing sustainable operations today requires meaningful simulation of future events, which in turn relies on the accurate representation of all relevant current knowledge. In decommissioning, human agents may be as important for maintaining operational safety as technical systems, so simulations ...

Composition and Contaminant Loads of Residual Household Waste Part III: Physico-Chemical Properties and Contaminant Concentrations
Abstract. Physico-chemical properties of residual waste are key factors for disposal standards. Reliable input data for treatment plants (MSWI) need to consider the heterogeneity and variability of waste composition. This requires thoroughly designed sampling schemes, a consistent separation of bulk waste into uniform fractions, and adequate methods for sample preparation and analysis. The ...

Measuring level by weight
Measuring level or inventory by weight provides high accuracy. The weight is not affected by ingredients that foam or settle unevenly or by changes in density or the shape of the tank. Weight is weight, regardless of percent solids, bridging, rat-holing, or whether your ingredient is conductive or sound-absorbing. Because weighing is a noncontact method of measuring level, there is no chance of ...

Evaluation of rational industrial solid waste abatement in China
Industrial Solid Waste (ISW) abatement is attracting wide attention, with its generation increasing rapidly in China. In this paper, we calculate the ISW rational abatement ratio (IRAR) of 30 regions in China from 1990 to 2005, by applying Data Envelopment Analysis (DEA). Results show that, the Eastern, Central and Western areas have the lowest, medium and highest 1990?2005 average IRAR (15.04%, ...
