Used cooking oil collection, managed across every location
From fryer oil collection to storage containers and rebates, Waste Harmonics Keter manages your used cooking oil as a single managed partner, not a broker. One point of contact, one invoice, documentation you can defend.
Used cooking oil is a commodity, not trash
Fryer oil has real market value, which is why it gets stolen off back docks and why unmanaged programs leak money. Most multi-site operators run it site by site, with a different collector in every market, inconsistent containers, spills nobody owns, and rebates nobody tracks.
We make used cooking oil collection consistent, secure, and documented everywhere you operate, and capture the value where markets allow.
What counts as used cooking oil service we manage
Used cooking oil is a recyclable commodity stream, from fryer oil and grease to the containers it lives in. We manage collection, storage, and routing to renderers through one consistent program across every location.

How WHK manages your used cooking oil program
We start by mapping what you generate across every location, then standardize your program with one cadence and vetted recyclers everywhere. Scheduled pickups come with chain-of-custody records, and your materials are processed responsibly with diversion and activity rolled into one report.
Assess
We map your locations, fryer inventory, oil volumes, current collectors, and where value or documentation is leaking.
Standardize
One program: right-sized secure containers and a collection cadence matched to fry volume at every site.
Collect & document
Scheduled collections with chain-of-custody records, and secure storage that keeps oil off the ground and out of thieves' hands.
Recycle & report
Oil routed to vetted renderers and renewable fuel processors; volumes, rebates, and activity rolled into one report.
Simplify, save, and optimize
Simplify
One managed partner across every location; we wrangle the haulers, recyclers, and paperwork.
Save
Right-sized pickups and consolidated, transparent billing replace one-off disposal fees and untracked spend.
Optimize
Documentation, diversion tracking, and reporting that stand up to audit and feed ESG goals.
A broker hands your assets to whoever's cheapest and disappears. We own
the outcome. Vetted recyclers, real people, full accountability

Why multi-site food generators trust WHK
We don't broker your program. We own the relationship at every location you operate, which means we're answerable for what happens from pickup to final processing.
Every facility in our network is vetted and documented. Chain of custody records follow your materials through every step, giving you the evidence you need for compliance and ESG reporting.
Consolidated data across all locations rolls into one report. No piecing together invoices from five different vendors or explaining gaps in your diversion numbers to auditors.
We own your program end to end, not as a broker passing you between vendors.
