“…Several types of methods have been developed to support end-of-life phase decision-making. Vanson et al (2022) distinguish between end-of-life assessments, disassembly assessments and other assessment methods. They showed that mathematical models, multi-criteria analyses (MCAs) and cost-benefit analyses are the most common types of methods within these categories.…”

The construction industry is increasingly challenged to reduce its waste production, resource consumption and energy emissions. Moving towards more circular and sustainable practices therefore seems imperative. Demolition contractors play a vital role in this move as they need to select waste management strategies for distinct obsolete building elements. Previous research has nevertheless overlooked how demolition contractors can gain insights into the consequences of such strategies. This research therefore adopts a design science research methodology to iteratively develop a decision-support tool for selecting demolition waste management strategies. Through collaborating with a pioneering demolition contractor in the Netherlands, in-depth insights into actual decision-making processes were obtained. A tool was subsequently designed that compares and ranks three different waste management strategies (reuse, recycle and recover) by evaluating their impacts in terms of technical feasibility, economic costs, environmental gain and social gain. This tool enables demolition contractors to make more informed waste management decisions and, as such, offers new opportunities to adopt circular and sustainable demolition methods. PRACTICE RELEVANCEDemolition contractors are pressured to adopt more circular and sustainable methods. This requires these firms to consider waste management strategies other than traditional energy recovery or landfilling. A new decision-support tool offers demolition firms insights into the consequences of different waste management strategies. This tool compares and ranks reuse, recycle, and recover waste management strategies. The tool was demonstrated and evaluated by a demolition contractor in the Netherlands. It was found that the decision-support tool assists in making more informed waste management decisions through illuminating technical feasibility, economic costs, environmental gains and social gains. A suggested ranking of strategies is provided for distinct obsolete building elements. Implementing the tool will require changes to local project routines.

“…Techniques upon which CE can be performed include reuse, remanufacturing, recycling, etc. (Vanson et al, 2022). For CE to be effectively implemented, a conscious effort must be made in regulatory legislation, governmental policy, administrative model, product design model, supply chain management, and waste management (Smol et al, 2020;Kazancoglu et al, 2021).…”

Municipal solid waste constitutes environmental challenges globally, especially in developing countries, due to increasing waste generation, population growth, inadequate infrastructure, lack of data and poor planning. This study aims to conduct a comprehensive waste audit on the municipal solid waste generated in Aba, a metropolis in southeastern Nigeria. Aba is a commercial city considered the messiest because of the massive municipal solid waste generation and poor management. The study investigated the energy potential and waste regeneration. Municipal solid waste data was sought to provide insight into the quantity and composition of municipal solid waste. The methodology was site-based, in line with the standard test method for determining unprocessed municipal solid waste (ASTM-D5231-92) and SowaCLINK software, a computer-based environmental application, was used for characterization. Linear extrapolation was adopted to quantify the rate of municipal solid waste generated. The geometric mean was applied to forecast the area’s population for a 10-year design period. The chemical elements of the characterized municipal solid waste were utilized based on the ASTM-D5291 standard for municipal solid waste thermochemical conversion, and the high and low heating values were analyzed. The outcomes provided energy recovery potential, the electrical power potential, and the power to the grid of electrical power of the municipal solid waste. The results obtained were 0.7813 kg/p/d and 490,268 t/y for a population of 1,719,185 persons. The percentage of the municipal solid waste components with energy potential was 71%, comprising 48% combustible and 23% organic components on average. The high heating value computed was 176.5 MJ/kg, and the low heating value was 14 MJ/kg. The energy recovery potential was 3,709,463 MWh, the electrical power potential was 38,680 MW, and the power to the grid was 26.1 MW daily. The research reveals a promising direction in transitioning from the linear economy of municipal solid waste management toward implementing an integrated sustainable municipal solid waste management based on the circular economy model. The study recommends adopting detailed steps to proffer solutions to the environmental challenges associated with municipal solid waste in most low-middle-income countries to achieve sustainable municipal solid waste management while generating electricity and bio-fertilizers through incineration and anaerobic digestion.
