What are waste audits?

A waste audit consists in assessing the quantity and type of waste produced by a company. It is a preliminary diagnosis before implementing a waste sorting and recycling solution. The waste audits help, among other things, to assess contamination in each stream, what could have been recycled, and what should not have been recycled. This assessment helps formulate appropriate residual waste collecting solutions and implement effective solutions for companies, who are responsible for the waste they produce right through to final treatment.

Become more efficient, cost-effective and environmentally friendly.

Companies often decide to carry out waste management audits in order to:

  • Improve their sustainability record due to environmental concerns and values. 
  • Reduce costs. Properly implemented waste reduction projects are usually cost-effective. 
  • Improve team satisfaction and commitment.
  • Meet the requirements of supply chain partners or other partners - Supply chain partners and other partners are increasingly asking companies to provide information on their waste reduction efforts, particularly in requests for proposals.

Why should you use waste audit services for your company?

Hazardous, mineral and non-mineral waste is often not optimally recycled. To improve recycling, your company's recycling audit is a crucial first step. It enables you to: 

  • Understand the quantity and types of waste produced;
  • Identify waste management costs;
  • Define the most appropriate waste recovery solutions.

Our waste consultants will take the time to understand:

  • How the company operates and the materials it uses
  • How and by what waste is produced in the company's various sectors
  • What materials are reused or discarded
  • How recycled materials are separated 
  • Current waste reduction efforts

The information provided by waste audits enables a company to better understand its waste management. It can then identify more precisely the waste it produces, how to optimize its recovery and draw up an action plan in line with its needs.

How can waste audit companies can benefit your company's health?

First and foremost, waste audits are good for the environment. According to a report by the province's Auditor General, only 15% of waste from companies and organizations is diverted (reused, recycled or composted). These figures show that this is far less the case in the residential sector, where 50% of waste is diverted.

Waste audits consulting services can also drastically reduce your waste management costs. With the rising cost of materials, it's more important than ever to manage resources efficiently and promote recycling and waste recovery. It's useful, even essential, to carry out an audit of your company's waste management in order to prepare a waste management plan adapted to your needs. 

A waste audit by a team of experts can help you better assess the nature of your needs. A site visit, identification of materials, analysis of equipment, existing management system and flows, and cost estimates all help to design a coherent and appropriate action plan.
