Minimizing Construction Site Pollution: Strategies For A Greener Future

Construction is a major contributor to pollution. The construction industry accounts for 23% of air pollution, 40% of water pollution, 50% of climate change-related pollution, and 50% of landfill waste. With the sector's significant environmental impact, it is crucial to explore ways to reduce pollution on construction sites. From adopting sustainable practices to implementing dust control measures and upgrading to greener machinery, there are several strategies that can be employed to mitigate the negative consequences of construction on the environment and human health.

Use greener fuel and local sources

Using sustainable sources of fuel and giving preference to local suppliers is an effective way to reduce pollution on construction sites. This limits fuel emissions from the travel time of supply chain vehicles and the carbon footprint of materials.

Sustainable Sources of Fuel

There are several ways to adopt more sustainable fuel sources on construction sites. One way is to ensure that vehicles are switched off when not in use and that there is no unnecessary use of site machinery. Effective forward planning can also help to prevent queues of supply chain vehicles in and around the site during peak construction periods, reducing emissions from idling vehicles.

Another way to reduce emissions is to upgrade to newer machinery. Older site machinery can be a major contributor to pollution and emissions. Hybrid technology is now available and can significantly lower fuel consumption and emissions, reducing the environmental impact of construction projects.

Local Suppliers

Prioritising local suppliers can also help to reduce the carbon footprint of construction projects. By sourcing materials locally, construction companies can reduce the fuel emissions associated with transporting materials over long distances. This not only reduces pollution but can also lead to cost savings for construction companies.

Additionally, using local suppliers can help to support the local economy and reduce the impact of construction on the surrounding community. It is important for construction companies to demonstrate that they are managing their pollution levels and reducing their impact on workers, local residents, and the environment. By adopting sustainable practices, such as using greener fuel and local sources, construction companies can reduce their environmental impact and contribute to global efforts to address climate change.

Repurpose buildings

Repurposing buildings is an effective strategy to reduce pollution on construction sites. With the changing economic landscape, many cities and towns across the UK have witnessed the departure of businesses, retail stores, and tenants as remote work and economic shifts have altered how we utilise spaces. By repurposing existing buildings, construction companies can significantly reduce air pollution as there will be no large-scale physical construction or land clearance. This approach not only lessens the environmental impact but also aligns with the Government's net-zero target by 2050.

The construction industry plays a significant role in contributing to air pollution, with construction and built environments accounting for 4% of particle emissions. Construction activities, such as the use of machinery, vehicles, and chemicals, release emissions that negatively impact both human health and the environment. Air pollution from construction sites includes particulate matter (PM2.5 and PM10) and volatile organic compounds (VOCs), which can lead to respiratory issues, lung cancer, and other serious health problems.

By repurposing buildings, construction companies can avoid the need for extensive demolition and new construction, reducing the release of these harmful pollutants. Repurposing can involve adapting and enhancing existing structures to meet new requirements, such as converting former retail spaces into offices or residential units. This approach not only reduces air pollution but also minimises waste and the consumption of new materials, contributing to a more sustainable construction process.

Additionally, repurposing buildings can help revitalise communities affected by economic shifts. Vacant and underutilised buildings can be transformed into spaces that cater to the changing needs of the local population, such as co-working spaces, community centres, or recreational areas. This not only reduces pollution but also contributes to the social and economic development of the area.

Furthermore, repurposing buildings can be a cost-effective strategy for construction companies. By working with existing structures, companies can reduce construction costs associated with new builds, making better use of resources and materials. Repurposing can also lead to faster project completion times, as extensive demolition and construction timelines are shortened, reducing the overall environmental impact of the project.

In conclusion, repurposing buildings is a crucial strategy for reducing pollution on construction sites. By adapting and reusing existing structures, construction companies can minimise air pollution, contribute to sustainability, support community development, and benefit from cost-effective construction processes. This approach not only aligns with environmental goals but also helps create more resilient and vibrant communities.

Monitor emissions with targeted monitoring services

One of the most important steps in reducing pollution on a construction site is to monitor emissions with targeted monitoring services. This means collecting accurate, real-time data on the emissions produced on-site, and understanding their impact on the surrounding environment and communities.

There are several ways to implement targeted monitoring services:

• Use of technology: Companies such as EMSOL provide real-time data by attributing pollution to specific vehicles or non-road mobile machinery (NRMM). This allows construction companies to take quick, proactive, and evidence-based action to improve pollution levels, rather than simply monitoring it passively.
• Air quality monitoring networks: Establishing a high-resolution air quality monitoring network is crucial for quantitatively measuring the impacts of construction activities and the effectiveness of any actions taken to reduce harm. This can be done through the use of monitors and modules that do not depend on infrastructure like WiFi or power, making them flexible and resilient during environmental disasters.
• Visual observation: In addition to technological solutions, construction companies can also employ visual observation methods to monitor emissions. This may include the use of drones or other aerial vehicles to inspect the site and identify any areas of concern.
• Data analysis: Collecting data is just the first step; it is essential to analyse the data to identify trends and patterns in emissions. This can help construction companies to identify areas where improvements can be made and to measure the effectiveness of any actions taken.
• Collaboration with experts: Construction companies can also collaborate with environmental scientists, engineers, and other experts to interpret the data and develop effective strategies for reducing emissions.
• Regular reporting: To ensure that targeted monitoring services are effective, it is important to establish regular reporting procedures. This may include creating reports on a weekly, monthly, or quarterly basis, depending on the specific needs and requirements of the construction site. These reports can help to identify any areas of concern and track the progress of any actions taken to reduce emissions.

By implementing targeted monitoring services, construction companies can take a proactive and data-driven approach to reducing pollution and mitigating the negative impacts of construction activities on the environment and surrounding communities.

Upgrade to hybrid machinery

Upgrading to hybrid machinery is an effective way to reduce pollution on construction sites. Hybrid construction machinery (HCM) is a crucial solution to the issues of environmental pollution and energy shortages.

Use water sprays to control dust

Water sprays are an effective way to control dust on a construction site. This method is often used by workers to mitigate dust during a project. By spraying water on dusty surfaces or materials, you can prevent dust from becoming airborne and keep it from rising into the air. This helps to protect the health of workers and nearby residents, as well as improve visibility and safety on the construction site.

One common approach is to use a water tank to keep the dust moist and prevent it from drying out and becoming airborne again. While this method is relatively inexpensive, it can be time-consuming as you need to continuously spray the dust to keep it under control. Additionally, water trucks or carts used for this purpose can be costly and may create problems with runoff and mud, impacting worker safety and causing issues with local councils.

To enhance the effectiveness of water sprays, certain chemicals can be added to the water. These chemicals, known as palliatives, are designed to bind the dust particles together and make them less likely to be kicked up into the air. However, it is important to note that palliatives can potentially pollute groundwater. Alternative options include tackifiers and polymers, which modify the soil surface to reduce dust, and polymer-based additives that create a protective seal over exposed surfaces or stockpiles.

For a more permanent solution, installing permeable pavers before beginning construction can eliminate dust from the ground up. These pavers, such as TRUEGRID PRO LITE and TRUEGRID PRO PLUS, offer durability and dust-suppression capabilities, providing a long-lasting solution to construction projects. They can be installed and disassembled quickly and are made from 100% recycled plastic, making them an environmentally friendly option.
