You have a biowaste problem. Could it actually become profitable?
For most companies, biowaste is a pure cost.
01 · The value
Nutritional value locked inside
$5–10/ton to landfill in developing countries. Over $100/ton in Europe. Money out, nothing back.
But certain waste streams — food processing waste, brewery byproducts, slaughterhouse residues — have nutritional value locked inside. They just can’t be used directly.
Biological waste processing is turning these streams into something valuable: protein-rich biomass, oil, and organic fertilizer. Not theory — facilities already operate at 5 to 50 tons per day, processing real waste in real conditions.
02 · The evaluation
The 3-step process
But it doesn’t work for every waste stream. Whether it makes sense for yours requires a structured evaluation.
Here’s the 3-step process we use after 8 years of doing this across dozens of countries. ↓
Step 1: What does it actually cost to process your waste biologically? This depends on waste type, volume, consistency, and local energy/labor costs. This step alone screens out cases that won’t work.
Step 2: What can the outputs be worth? Clean food waste → feed-grade protein and oil worth hundreds per ton. More challenging waste → extractable nutrients for industrial applications. The outputs don’t have to be animal feed to be valuable.
Step 3: How does this compare to what you pay today? Landfill fees? Biogas contracts? Composting? At small-to-medium volumes, biological processing often wins on capital cost alone — starting at a fraction of what a biogas plant requires.
03 · Honest answer
Sometimes it’s not the best option
The honest answer: sometimes it’s not the best option. Very large volumes with energy subsidies may favor biogas. Low-nutrient garden waste is better composted. We tell clients this when it’s the case.
04 · The expertise
What the evaluation requires
Each step requires specialized knowledge that takes years to build. Getting any one of these wrong turns a promising project into an expensive mistake.
If biowaste is a cost line in your business — there may now be a better option worth exploring.
