What factors contribute to the economic viability of using recycled aggregates?

Using recycled aggregates is economically viable primarily due to the cost savings on disposal. When construction or demolition materials, such as concrete and asphalt, are disposed of in landfills, there are typically significant disposal fees. By recycling these materials and reusing them as aggregates, contractors can reduce or eliminate these costs. This not only contributes to lower project expenses but also supports sustainable practices by minimizing waste and prolonging the life of existing materials.

In addition to disposal cost savings, using recycled aggregates can often lead to reduced sourcing costs, since these materials can be sourced locally and do not require the extraction and processing that natural aggregates do. This aspect enhances economic viability by reducing transportation costs and promoting local economies.

Other factors, such as increased shipping costs, higher processing fees, and less availability of resources typically do not favor the use of recycled aggregates. Shipping costs can rise if recycled materials are not sourced locally, while higher processing fees would negate some of the savings achieved through recycling. Moreover, if resources are less available, it indicates a possible shortage or increased demand for these materials, thereby conflicting with the premise of using recycled aggregates as a cost-effective solution.
