Hazardous waste costs are driven by three things: the volume you produce, how difficult the waste is to treat, and how efficiently it is collected. Every one of those can be reduced without cutting a single compliance corner. Here are five changes that pay for themselves quickly.
1. Segregate properly at source
A mixed load is priced against its most difficult component. Put a litre of solvent into a drum of waste oil and the whole drum becomes solvent for pricing purposes. Separate bins, clear labels and a short toolbox talk usually save more money than any negotiation on rate. Clean, well segregated waste oil also opens up regeneration routes under waste oil disposal, which is normally cheaper than incineration.
2. Keep water out
Rainwater in an open drum, a leaking roof over a storage bay or a wash down that drains into the wrong container all add tonnage you pay to remove. Covered, bunded storage costs very little and removes the problem, and it reduces the load on your interceptor, which we service through interceptor and contaminated water disposal. Practical guidance is in how to store hazardous waste safely on site.
3. Right size the collection
Paying for a dedicated vehicle to collect two drums is expensive. Paying for storage that overflows because collections are too infrequent is expensive in a different way. The sweet spot is a scheduled round matched to how quickly your store fills, with the option to add an extra visit when a project generates a spike. We build this into quotes for chemical waste disposal and solvent disposal as standard.
4. Reduce what you buy in
The cheapest hazardous waste is the one never created. Review purchasing: are part used containers being thrown away because a smaller pack size was not available? Is a solvent based product doing a job a water based one could do? Is stock rotating, or are chemicals expiring on the shelf and coming to us as unused product? Sites that audit their chemical store usually find a straightforward reduction in the first year.
5. Classify accurately and keep the paperwork tidy
Rejected loads are the hidden cost in hazardous waste. A load rejected at the treatment facility means a wasted journey, a return charge and a rebooking. Accurate descriptions and correct List of Waste codes prevent almost all of them. If you are not sure what you hold, get it sampled before it is collected rather than after. The classification basics are covered in what is hazardous waste, and the documentation is explained in do I need a hazardous waste consignment note.
A note on cheap quotes
A rate that looks far below the market usually means the waste is going somewhere you would not choose, or that charges appear later as surcharges for containers, paperwork, waiting time or rejected loads. Duty of Care follows your waste to its final destination, so a cheap collection that ends badly is still your problem. The checks to make are listed in Duty of Care for waste producers.
Where to start
Walk your storage area, list the waste streams you produce, and note which are mixed, wet or unlabelled. Fixing those three things typically delivers the fastest saving. Send us the list and we will quote against it and suggest a collection pattern that fits your site. See all our hazardous waste services.
