What is one of the environmental benefits of using recycled aggregates?

Using recycled aggregates contributes to a reduced carbon footprint from material processing, which is an important environmental benefit. When recycled materials, such as concrete or asphalt, are utilized, it minimizes the need for extracting and processing virgin materials. This reduction results in lower emissions of greenhouse gases that are associated with the production and transportation of new aggregates.

Moreover, recycling aggregates not only decreases the carbon output but also lessens the overall energy consumption involved in the production process. By choosing recycled aggregates, projects can help divert waste from landfills, promote sustainability, and conserve natural resources, all of which align with environmental best practices.

In contrast, the other options highlight negative or less favorable aspects related to the use of aggregate materials. For instance, increased landfill capacity does not directly associate with environmental benefits but rather with waste management. Higher energy use in production contradicts the principles of sustainability, and damage to natural resources is a concern that recycled aggregates aim to minimize. Thus, the focus on reducing the carbon footprint through the use of recycled aggregates underscores its significant positive environmental impact.
