Best Practices for Waste Management in Construction
(While Remodeling or Renovating)

Remodeling and renovation projects are subject to tough budgets and operate at a frantic pace. Project managers rarely have time to consider waste management, but as a result, they may be ignoring a potentially huge cost center.

The Benefits of Best Practice Waste Management

On paper, waste disposal may be under 1% of a construction project’s costs. However, the disposal cost is just one of the elements that contribute to make up the ”true” cost of waste.

When taking into account the cost of the original materials, transportation and storage, and the labor required to fill the dumpster, the true cost of waste in the construction industry is generally quoted to be 10-20 times greater than the disposal cost. Applying this 10-20% factor, the true cost of waste for a construction project is actually between 2 and 10% of the total project’s costs.

And on average, it’s estimated that 13% of raw materials are discarded unused. This presents significant potential to improve purchasing efficiency and reduce procurement costs through effective waste management.

By implementing best practice waste management on your sites, your business can benefit from:

  • An additional source of income by collecting materials for reuse.
  • Lower procurement and disposal costs by purchasing less material and maximizing dumpster space.
  • Fewer site accidents with safe storage of materials and timely collections keeping your site tidy.
  • Compliance with all waste management legislation for safe and appropriate management and disposal of site materials.
  • Enhanced business reputation as a responsible, informed contractor.
  • Reduced carbon footprint and increased environmental performance.

So what does it take for your sites to follow best practice waste management?

Design Out Waste

The best way to reduce the amount of waste generated on site is to design it out at the beginning. This means making design decisions that prevent waste from being produced in the first place, increase the amount of recycled content used within the build, and increase the future recyclability of the materials when they reach the end of their life.

Where it’s not possible to plan or design so that waste is avoided on site, then you can still save money and resources by reusing and recycling as much material as possible during the works.

Create a Site Waste Management Plan

Using a Site Waste Management Plan (SWMP) on your remodeling and renovation projects provides you with a powerful process to improve waste management performance and reduce costs.

The SWMP has three main purposes:

  • To improve the resource efficiency and profitability of your projects.
  • To increase staff awareness about best practice waste and material management on site.
  • To ensure that your sites remain in compliance with all waste and recycling legislation.

Reuse and Recycle All Available Materials

There are many opportunities to reuse and recycle more materials on a remodeling or renovation contract.
To increase the amount of materials that can be reused, you can:

  • Designate a storage space to keep unused materials, ready for reuse.
  • Collect lumber and drywall offcuts, half bricks and blocks. Ensure that the entire team know that these are available for reuse.
  • Coordinate projects so that leftover materials from one can be used on the next.
  • Use a mini crusher and screener to create aggregate from leftover bricks and rubble, reducing disposal costs and aggregate procurement costs.
  • Identify suppliers who use and collect returnable packaging like pallets and crates.

To increase the amount of materials that can be recycled, you can:

  • Segregate all waste materials, and keep hazardous materials out of mixed waste containers. This will reduce disposal costs and increase the value of the end materials.
  • Get your mixed waste container collected by a hauler than can sort the materials at a Materials Recovery Facility (MRF), instead of a landfill site. This can reduce the cost of disposal.
  • Identify haulers who will recycle each of your waste streams.
  • Track the markets for materials like wood, metals, & aggregates, to ensure that you are getting fair disposal costs – or rebates.
  • Work with suppliers who use recyclable packaging, or who will take your packaging waste away and recycle it for you.

Concrete is an example of a waste material that many construction sites overlook. Concrete constitutes around 70% of C&D waste, and as it’s heavy, the disposal costs over a remodeling or refurbishing contract can be significant.

Fortunately, concrete doesn’t have to turn to ‘waste.’ If it is not contaminated with trash, wood or reinforcing materials, it can be recycled on site with portable crushers, maximizing efficiency in your workflow and keeping waste costs down.

Closely Manage Your Haulers

Remodeling and renovation job sites are busy places and if waste builds up, accidents can happen. Project managers sometimes have to make emergency call-outs for their dumpsters to be emptied to enable their sites to function safely, however, these are generally much more expensive. Proactive management of your waste volumes and haulers during the project will enable collections to be optimized, generating considerable savings and keeping sites safe.

Equally, when trucks come to site to service your dumpsters, they must operate according to site safe working practices, and be scheduled to avoid peak activity periods to ensure optimal site safety.

Effective hauler management also includes auditing their invoices. If sites are using multiple haulers, this means that project managers have to review multiple invoices each month. And considering that 4 out of 5 waste invoices have up to 30% in extra fees or overcharges, it’s imperative that each of these gets reviewed thoroughly.


If this all sounds like too much for your project managers to deal with on their own, then you might benefit from the help of an expert waste management company.
