The Situation
A major pet food manufacturer produces a wet by-product whenever production lines are flushed between protein changeovers — for example, switching from a lamb product to chicken or beef. Each changeover can flush one to two tonnes of this material.
Because it’s a putrescible waste — organic material that rots — it can’t go to regular landfill and had to be sent to deep burial, a costly and unsustainable method. The client was paying around $600 per tonne and was looking for a cheaper, more sustainable solution.
Our Approach
Evoro set out to find a recovery route rather than simply a cheaper disposal one. This involved several key steps:
Investigate viable recovery routes
Test the material’s suitability with third parties and work through the regulatory requirements for diverting a putrescible stream.
Establish a licensed compost pathway
After exploring several options, secure a route to a licensed compost facility able to take the product and turn it into compost.
Deliver a complete daily service
Offer a complete removal and diversion service at roughly half the client’s previous disposal cost, servicing the site daily.
The Results
Evoro now services the site daily, moving on average two bins a day — and at times three — equivalent to around 13 to 15 tonnes per load.
The environmental outcome is the headline: roughly 3,000 tonnes of material a year that was previously buried is now diverted into compost and re-lifed into a reusable product. For a client under growing ESG and sustainability-reporting pressure, that’s a waste stream they can now report as fully diverted from landfill.
The solution also roughly halved the client’s disposal cost, saving an estimated $500,000 to $750,000 a year.
Diversion is the outcome clients can report.
Recovering a stream that once went to deep burial does two things at once: it cuts cost, and it gives the client a landfill-diversion result they can stand behind in their own ESG reporting. That’s the recovery-first model turning an environmental philosophy into a measurable number.
