How to conduct a waste audit in the Office sector
A waste audit is a hands-on review of the different types of waste your business produces. It can be conducted at a high level, for example reviewing all waste for a building with one or more tenants, or at a more detailed level, for example reviewing waste per department or process area.
The idea of a waste audit is to identify where waste is generated in your workplace or facility. With this knowledge, you can take steps to reduce it and ensure your business complies with legislation concerning waste handling, storage and disposal.

Undertaking a waste audit will help you to establish:
What types of waste your business produces
Where waste is generated in your business – whether for the whole building or for each tenant, workspace or department
Who generates waste in your business
Once complete, you can then develop a waste action plan with your priorities and targets for reusing, recycling and recovering your waste.
Good to know
Your existing waste or recycling , if you have one, may be better placed to undertake the audit process for you – especially if your waste may include items that could cause an injury, such as broken glass.

Your waste audit template
1. Conduct a risk assessment
You should produce a risk assessment before undertaking a waste audit to ensure that you’ve considered and mitigated all risks, such as those entailed by manual handling. Ensure that all relevant colleagues are properly briefed on the task before starting the audit, including your Health & Safety officer or team.
Additional care should be taken if your waste is likely to contain potentially .
2. Collect your waste
Gather your waste, including general waste, all recyclables, kitchen waste and waste from litterbins, if applicable.
3. Sorting
If it’s not already segregated, tip the waste onto your tarpaulin or plastic sheet and sort it into the different material types using your sorting containers. Use the waste audit template as a guide when deciding the number of different material types.
4. Measuring
Weigh each type of waste, remembering to deduct the weight of the container to arrive at the of the material.
5. Recording
Weigh each type of waste, remembering to deduct the weight of the container to arrive at the net weight of the material.
6. Repeat twice
Where possible, it’s a good idea to repeat the audit (steps 2-5) twice more (three times altogether) during a week, taking account of days when you know it’s busier and quieter, and average your totals. This will provide a more accurate picture of the types and quantities of waste and recycling your business produces.
7. Calculate your results
Using the average net weight for each material stream, calculate your annual waste and recycling total. Calculate your annual waste production, for example by multiplying by 52 if you have measured by the week.
Tips for carrying out your waste audit
Choose the right location and date(s) for your audit – the best time to undertake it will be the day before your waste is collected
Secure a suitable area for opening and containers and sorting the waste materials
Keep your audit dates secret so that employees won’t change their behaviour and skew your results, but make sure that cleaners and facilities staff know so they don’t empty the bins.
