“…In particular, inappropriate deposition of demolition waste has resulted in serious environmental issues in Malaysia [64]. Only 15% of overall demolition and construction waste in Malaysia are recycled annually, which is far behind countries such as Singapore, Germany, and South Korea, with the rate of 50%-75% [65]. Malaysia generates 26,000 tonnes of construction and demolition waste daily, leading to the generation of nearly 10 million tonnes of wastes annually [65].…”

Malaysia generates 26,000 tonnes of construction and demolition waste daily, leading to the generation of nearly 10 million tonnes of wastes annually [65]. According to Nagapan et al [66], a study of 30 demolition sites in Malaysia showed that concrete comprised 12.3% of the total demolition waste.…”

“…Manning et al [79] measured sequestration capacity of 6 tonnes CO 2 ha −1 year −1 for the top 10 cm of soil at the site containing 50% dolerite fines (which has similar material composition to basalt) and 50% compost. Considering annual generation of nearly 1.2 million tonnes of demolition concrete wastes [65] and 62,000-69,000 tonnes of basalt quarry fines [80], these materials can be used for inorganic CO 2 sequestration in Malaysia, if the function is designed into the first 10 cm of land associated with the country's future developments. Taking the availability of demolition concrete waste and basalt quarry fines into consideration, and assuming an application rate of 100% demolition concrete waste and 50% basalt + 50% compost, Malaysia has the capacity to annually establish 1043 and 85 ha of land suitable for inorganic CO 2 sequestration using demolition concrete waste and basalt quarry fine, respectively.…”

Sequestering Atmospheric CO2 Inorganically: A Solution for Malaysia’s CO2 Emission

Malaysia is anticipating an increase of 68.86% in CO2 emission in 2020, compared with the 2000 baseline, reaching 285.73 million tonnes. A major contributor to Malaysia’s CO2 emissions is coal-fired electricity power plants, responsible for 43.4% of the overall emissions. Malaysia’s forest soil offers organic sequestration of 15 tonnes of CO2 ha−1·year−1. Unlike organic CO2 sequestration in soil, inorganic sequestration of CO2 through mineral carbonation, once formed, is considered as a permanent sink. Inorganic CO2 sequestration in Malaysia has not been extensively studied, and the country’s potential for using the technique for atmospheric CO2 removal is undefined. In addition, Malaysia produces a significant amount of solid waste annually and, of that, demolition concrete waste, basalt quarry fine, and fly and bottom ashes are calcium-rich materials suitable for inorganic CO2 sequestration. This project introduces a potential solution for sequestering atmospheric CO2 inorganically for Malaysia. If lands associated to future developments in Malaysia are designed for inorganic CO2 sequestration using demolition concrete waste, basalt quarry fine, and fly and bottom ashes, 597,465 tonnes of CO2 can be captured annually adding a potential annual economic benefit of €4,700,000.

Construction and Demolition Waste and Its Management Challenges in Iran: A Case Study in Tabriz City

et al. 2019

Background: The management of construction and demolition (C&D) waste is among the fastest-growing concerns in Iran. Moreover, the basic prerequisites for the effective performance of every waste management program are the accessibility of adequate and precise data on characteristics and its current management condition. Objectives: Estimating the amount of C&D waste in Tabriz metropolitan city (Iran) was one of the key aims of the current study. Another objective of this study was to evaluate of C&D waste handling and their final disposal. Methods: The C&D waste generation rate was estimated according to the waste weight per area of construction and demolition in Tabriz. Then the C&D waste management condition was assessed using a checklist, visiting the disposal site, intervening authorities, and analyzing scientific databases. Results: The amount of C&D waste generation rate in the Tabriz city was estimated to be in the range of 167034 to 848480 ton/year or 0.114 to 0.534 ton/year per capita and 2.267 ton/m 2 of demolition. In this area, like most other parts of the country, no scientific and systematic program was observed for source reduction (reduce, reuse, and recycle of the C&D waste). Due to the non-availability of any standard disposal site, all the C&D waste (except for some recycled items such as metals) were deposited at the nearest distance from the city in public lands, waterways, valleys, roadsides and so on. Conclusions: According to the findings there is a great urgent need for applying specific practical policies, rules, and regulations for source reduction (reduce, reuse, and recycle (3R)) of C&D waste. Moreover, a central disposal site should be allocated to dispose of the remaining C&D waste according to the environmental and health considerations.

Factors such as migration and urbanization, arising from the demands of middle class for better living and conditions combine to give the sector this rapid growth [8]. The contribution of construction industry towards the global gross domestic product (GDP) of the developed countries revolves around 10 % of their total annual budget.…”

Abstract. This paper reviewed the existing literature on effectiveness of construction waste minimization in Nigeria with particular interest in Bauchi State. The study highlighted the menace of construction waste to the environment. The Nigerian construction industry comprises foreign and indigenous firms which are classified into small, medium and large according to their level of capitalization and annual turnover. In the real industrialized countries, the construction industry can be responsible for up to 20 % of the GDP and employs up to 12 % of the total labour force. In Nigeria, the sector contributes 3.2 % of GDP. This is a clear indication that construction industry in Nigeria failed to meet expectations of governments, clients and society. The material and method of this research study utilized a secondary source of data. A critical review of this recent journal articles posited new findings of effectiveness of construction waste minimization. To ascertain the actual happenings in the construction industries within and beyond the study area. The findings of this research study indicated that environmental pollution is caused by construction waste in the study area. It is also revealed that indigenous firms generate large volume of construction waste. It was evident that construction waste is ineffective to the health condition of the environment. The conclusion is drawn from the study also revealed that different approach and method should be applied to curtail and minimize construction waste effectiveness in the study area.
