Do you know that taking out the trash could be costing your business money? From the disposal of food scraps to pharmaceutical waste, glass, and organic waste, your company's daily operations produce waste.
Waste management should be essential to your business objectives as a business owner. Not only does it help your company save money, but it also allows you to support sustainability goals that have become important to today’s consumers.
According to Great Forest, 77% of trash thrown away by most companies is not trash at all. This means that most companies may lose valuable recyclables and pay too much for waste removal.
For effective waste management and waste reduction, you need to get data. This is where carrying out a waste audit comes in.
In this article, we will look at what waste audits are, why and how you can benefit from waste auditing, and simple steps to carry out waste audits for your organization.
A waste audit or waste stream audit is the process of analyzing an organization’s waste stream. In other words, a waste audit studies certain types of waste and how much waste a business produces.
A waste audit aims to collect information about the various waste streams in your company. Waste auditors will sort out and analyze different trash bags and recycling bins samples to identify, measure, and record the waste produced daily or weekly in your company. Auditors will also examine how much waste is recycled, composted, or sent to landfills.
With a waste audit report, you can identify mistakes your company has been making when it comes to disposing of waste. You can also get insight into how to promote your waste reduction goals and save money.
So why should you carry out a waste audit for your company? Well, waste audits come with multiple benefits. With a waste audit, you can get information to help your waste management goals and also cut down waste from landfills. Also, waste audits are required for companies looking to get a LEED Certification and some other zero waste certifications.
Here are a few benefits of waste audits:
To correctly manage waste from your company, you need to measure the waste your company disposes of.
A waste audit will help your company determine the materials that are recyclable, compostable, or materials that you should take to landfills. With findings from your company’s waste audit, you can create opportunities to educate employees on the costs of waste disposal and the importance of waste diversion.
With less waste generated, you will pay less to haul away waste. A waste audit can reveal areas that produce more waste and help you find innovative ways to reduce waste. With data from a waste audit, you can manage waste at all stages of business and reduce costs drastically.
With data from your company’s waste audit, you can cut down on waste disposal and find ways to recycle different materials like plastic, glass, and paper. Instead of disposing of valuable materials, you can find ways to recycle or reuse them. For example, instead of disposing of your cardboard packaging, you can reuse them.
With an audit, you can take the guesswork out of waste management. Audits will help you see what’s working and what's not with your waste management programs. You can uncover wasteful activities and measure the success of your recycling programs.
For example, with an audit, you can discover valuable recyclables which end up in the garbage. A waste audit reveals your waste diversion rate and helps you make adjustments that further increase your overall efficiency.
A waste audit is a major requirement for different certification standards like Leadership in Energy and Environmental Design (LEED). For example, one of the requirements for a LEED is a review of 100% of ongoing waste streams. Also, a waste audit will help your company follow local laws and avoid fines and penalties. It may also prove the prompt you need to pursue zero waste in your business and become a more sustainable business.
Now you know the benefit of a waste audit. Let’s look at a few steps to conduct your waste audit.
Planning your waste audit is an essential part of the entire process. You will need to assemble your team and decide where and when the waste auditing will occur.
Firstly, you need to assemble your audit team from key members of your organization. You want to pick the best green members from all levels of your company. From the senior leaders to junior leaders and the safety and janitorial staff. When selecting your team, keep your sustainability goals in mind. You want to pick a team that is flexible to changes.
Next, you want to choose a week to complete your audit. You want to choose a week with no special events to get an accurate idea of what waste comes from your company on average. Lastly, you want to take note of various waste disposal locations that your team will visit to collect waste samples.
The next step to implementing a waste audit is to find what type of trash your company produces. Before the week of your audit, create a list of the most common types of trash that your company produces. For example, you can categorize your audit trash into:
To ensure the safety of each team member, you will need to gather some tools and supplies. Here are a few things you will need for the audit:
And now the action begins. Start by collecting trash samples from various locations in your company and round up all the trash by the end of the week. You may want to label all the trash bags with the name of the department they came from.
Next, check the weight of the trash as well as the recyclables to know what the trash is and what you recycle every week. Next, sort everything in separate boxes, taking note of the recyclables mixed with waste, i.e., materials that haven’t been disposed of properly. Once your team has sorted everything, you want to find out the weight of each category. You can record the entire process using your clipboard, pen, camera, and phone.
After sorting the trash, the next step is to analyze your findings. You want to calculate your waste diversion rate, which is the rate of the weight of your recyclables divided by the overall weight of your trash. You also want to examine the weights of different categories, including waste not correctly disposed of. Take note of the mistakes made and identify areas of improvement. You can choose a member of the team to create recommendations and determine waste diversion goals for the company.
After analyzing your results, the last step to complete your audit is to implement changes in your company. This could be to reduce waste, increase the number of bins in your organization or make adjustments to your waste management program.
Here are some strategies you can implement in your company:
Carrying out waste audits is great, but it is even more important to follow up on your new action plan. You can have meetings with your team to analyze progress made and celebrate milestones. You also want to set new goals to encourage improvement. As you implement new strategies to reduce waste in your company, you want to make sure you develop continual improvement plans.

Food waste is not only produced by consumers but also by various food service facilities like restaurants, bakeries, bars, etc. If your business falls in the food service industry, you may also want to carry out food waste audits. Here’s how to go about food waste auditing:
Waste diversion is the process of diverting waste materials from a company or facility to reprocessing centers like a recycling or composting center instead of a landfill. Waste diversion rates refer to the rate at which you divert waste from your facility without burning them or sending them to the landfill.
To calculate your waste diversion rate, you need to start with waste audits. Typically, when completing your audit, you will need to group your waste into categories like recyclable items, compostable items, and general trash.
With data from your audit, you can find out the weight of each bag your organization collects. To calculate waste diversion rates, divide the weight of diverted waste by the weight of all the waste multiplied by 100.
Understanding your waste diversion rate will help you measure the success of your company’s recycling program and other waste reduction efforts.
