The construction and demolition (C&D) industry plays an integral role in supporting the ever-growing global population by providing essential infrastructure such as residential buildings, commercial complexes, and industrial spaces. However, this rapid expansion results in a significant environmental burden, as the construction industry generates a staggering amount of waste each year.
C&D waste is responsible for approximately 40% of all solid waste produced worldwide, contributing nearly 100 million tons of waste annually in the United States alone. This immense amount of waste has serious environmental consequences, but fortunately, there are a number of strategies that construction and demolition companies can use to reduce waste generation and promote sustainability.
While eliminating waste entirely is an unrealistic goal, reducing the amount of waste produced during construction and demolition projects is very achievable. Below are several key strategies that can be employed to help minimize waste, reduce costs, and lessen the environmental impact of the C&D industry.
Before we dive into specific waste reduction strategies, it’s important to understand some of the main causes of waste in construction and demolition projects. One significant cause is the lack of waste reduction efforts during the design phase. A study conducted by environmental engineers revealed that improper planning accounts for as much as 33% of all construction waste produced.
In addition to planning flaws, other common causes of C&D waste include design errors, last-minute changes to the project, improper material handling, poor site management, and inadequate knowledge of local waste disposal and recycling regulations. With so many potential causes, it’s easy to understand how waste can accumulate quickly.
To combat these issues, C&D companies can implement a variety of waste reduction tactics throughout the course of a project. One of the first steps is to develop a comprehensive waste management and recycling plan based on the specific materials used, the size of the project, and the available disposal services in the area.
This plan should outline measures to minimize waste generation and ensure proper disposal of materials. Utilizing roll-off dumpsters designed for C&D waste, employing construction-grade compactors, and working with specialized waste removal services are all effective strategies for reducing the volume of waste on-site.
An additional and highly effective waste-reducing tactic is opting for deconstruction over traditional demolition. Deconstruction allows for the careful dismantling of buildings, enabling the reuse of materials such as wood, steel, and concrete. This not only reduces the demand for new resources but also significantly reduces the amount of waste that ends up in landfills. Moreover, deconstruction releases fewer pollutants and toxic substances, making it a more environmentally friendly option compared to traditional demolition methods.
By adopting these waste reduction strategies, construction and demolition companies can minimize their environmental footprint and contribute to a more sustainable construction industry.
