The construction industry is faced with many challenges, among which is waste management. Aside from the fact that wastage contributes to time and cost overrun, it also has environmental implications in the form of pollution. However, the industry has the capacity to effectively manage waste, from generation to disposal. All stages of the management process are important, but scholars and governments have provided the final step, being disposal, unabated attention in order to ensure effective management. Potential waste disposal methods, including incineration, burning, landfilling, recycling, reuse, open dumping, pyrolysis, and shredding have emerged from the literature around the globe. Despite various waste minimisation and sustainable disposal options that are available, construction material waste is still increasing in Nigeria, while disposal remains a major issue for firms and government. Therefore, this study assesses disposal methods among construction firms to determine whether there is a relationship between their practices towards waste disposal. The research followed a concurrent triangulation design in a cross sectional survey, while data were collected via a convergent parallel mixed methods. The quantitative phase employed a structured questionnaire to collect data from 243 building construction firms, while the qualitative phase involved semi-structured interviews with 65 professionals from 10 on-going construction projects in Lagos, Nigeria. The research revealed that landfilling is the most common method of waste disposal, which is closely followed by reuse as backfill and recycling. In addition, the study revealed no association between company’s ownership statuses, age, project specialisation, and disposal methods, except company’s size. In conclusion, the study establishes the need for regulatory policies, such as site waste management plan (SWMP), pay as you throw (PAYT), and landfill ban, which would minimise material waste and divert them from landfills. Recycling and reuse are recommended as sustainable approaches for waste disposal.

Waste Management System

Waste management is one of the biggest problems facing the world in any developed or developing country. An important aspect of waste management is that the waste bin in the open space is properly filled before the next cleaning process begins. This can eventually lead to various hazards such as dirt and bad odor in the area, which can lead to the spread of various diseases. Population growth has significantly reduced toilets through the waste management system. Laying garbage in public places creates a polluted environment. To eliminate or reduce waste and maintain good hygiene, it requires a waste-based waste management system. The need for proper waste management is not limited to proper collection and disposal of waste. It continues to be a waste disposal and recyclable level. Recycling is considered a major benefit because in addition to waste disposal, our reliance on immature materials is declining. By recycling metal, plastic and glass, the use of decomposing waste can extend beyond compost and manure. Metals can be reused and plastic can be mixed with clay filler, which can lead to soil compaction. After deep cleaning the glass construction material can be broken down and re-melted into new articles. This article is about machine learning and the use of artificial intelligence in the most viable areas and understanding the full need for human communication.

In Ethiopia, the rapid expansion of the construction sector has resulted in the wastage of construction materials that negatively affect the environment, society, and the economy. The reason is inefficient waste management strategies practiced in construction projects. Hence, an adequate material waste management strategy is required. This study was an attempt to identify the key techniques that can help to minimize material wastage in building construction projects. Questionnaire surveys, interviews, and reviews of previous studies and related literature were employed in gathering the relevant data. Seventy of 85 questionnaires administered and distributed to contractors, consultants, and clients were returned. These data were analyzed using the relative importance index method. The results indicated that employing waste management officers for this purpose, using prefabricated or off-site production of components, appropriate on-site waste management, and incorporating a policy of material waste minimization plan were identified as key measures to minimize construction material wastes.

Concrete Production

Sustainability is an effort to build an infrastructure by considering the environmental impacts that occur. Concrete production as a construction material that commonly used in infrastructure development is one contributor to carbon dioxide (CO2) emissions. CO2 is produced from the calcination process in the manufacture of cement, burning of fossil fuels, and electrical energy used. More specifically by reviewing the calcination process on cement making, it has evaluated the consumption of cement in concrete production. The Life Cycle Assessment (LCA) is an environmental impact evaluation in terms of the life cycle of a product, wherein this paper, using the cradle-to-cradle scope, LCA is used as a method to evaluate cement consumption in concrete production to concrete waste management by taking concrete waste at Construction Laboratory and Materials Diponegoro University, Semarang for the case study. The results of the evaluation stated that the use of geopolymer concrete with fly ash as a substitute for cement could reduce up to 80% CO2 emissions with concrete strength 75% larger than conventional concrete. And for the concrete waste management, Construction Laboratory and Materials Diponegoro University reused concrete cylinder waste as a substitute material to build the retaining wall.

Coal, as a fossil fuel, is used to generate power for industrial operation. Two types of industrial ash, including fly and bottom ash, which are solid residues arising from coal burning, are dumped to the landfill with no care for reuse. These wastes consist of environmental issues needing to be resolved. The ashes are used in the production of cement, concrete, aggregates, adobe, brick, and insulation material, in the construction of dam and road, and in geotechnical applications. Construction material is a form of cementitious materials based on ash as source material and it is an environmentally friendly choice against Portland cement releasing a large amount of greenhouse gas to the atmosphere during energy intensive manufacturing process. It is a good alternative to the solution of environmental problems based on the waste ashes in the international scale. In addition to its economic benefits, it is suitable for industrial symbiosis. This chapter explores the reusability of ashes for the building sector to strengthen the sustainability of waste management.

Solid waste management is a global issue persisting in most of the developing countries like Pakistan. Current study briefly appraises the management and practices of municipal solid waste (MSW) in Bahawalpur city. Data were collected from different sources by using an in-depth interview and questionnaire tool. The findings reveal that domestic organic waste accounts for about 35.32% followed by debris, dirt and construction material waste (30.89%). About 273.69 tons solid waste is generated on daily basis whereas only 218.95 tons per day is collected and disposed. The collection rate of MSW varies from 61% to 80% in the city. The service coverage area was about 70%. The total sanitary staff was also very limited (735) as compared to the increasing population and served only 75% population of the Bahawalpur. The equipment and machinery used for MSW collection and disposal operation were also limited and out of fashion which were needed to be replaced. There is no proper landfill for disposal of solid waste which is openly thrown at five dumping sites and burned. This situation further creates many environmental and health issues. Recycling is almost absent in the city and behavior of the inhabitants also adds to an ineffective solid waste management in the city. It is necessary to create awareness among the people about bad effects of improper dumping of solid waste and the need to tackle this problem.
