How Food Manufacturers Cash In on Waste
Food manufacturers have spent decades treating production waste as a cost center. Trim waste from processing lines, spoiled batches, peels and cores, expired inventory…all of it has traditionally meant one thing: paying someone to haul it away.
That’s changing fast. Across the country, food manufacturers are finding that the organic material they used to throw into a landfill or pay to dispose of can actually be repurposed for land application, compost, or even animal feed. The shift isn’t just about doing the right thing for the environment. It’s about diverting recurring production waste from the landfill and meeting sustainability goals.
The Numbers Tell the Story
The food waste management market has grown into a major industry. According to recent market analysis, the global food waste management market size is projected to grow to $132.17 billion by 2034, driven by businesses finding practical ways to extract value from what used to go straight to the landfill.
This growth isn’t happening because companies suddenly care more about the planet; it’s happening because the business case has gotten stronger. New technologies, better markets for byproducts, and smarter logistics have made waste conversion financially attractive for operations of all sizes.
Animal Feed: Your Waste is Someone’s Ingredient
One of the most established revenue streams from food manufacturing waste is the animal feed market. Expired products, overruns from production lines, items damaged during manufacturing or packaging, products that don’t meet quality specifications for retail sale, and similar food manufacturing byproducts can all be processed into animal feed ingredients.
The global animal feed market was valued at $483.81 billion in 2025 and is predicted to increase to $503.17 billion in 2026, with a significant portion of that coming from food manufacturing byproducts. Rather than paying fees to dispose of organic waste, manufacturers can redirect these materials to feed processors or livestock operations.
The specifics depend on your waste stream. Bakery operations often work with dairy farms or feed mills to convert day-old bread and dough trimmings into cattle feed. Produce processors can sell pulp, peels, and cores as feed ingredients. Even coffee grounds and spent grain from breweries have established markets.
Biogas: Turning Organics into Energy and Cash
For food manufacturers with higher volumes of wet organic waste, anaerobic digestion offers another revenue path. The process breaks down organic material in sealed tanks without oxygen, producing biogas that can be used for electricity, heat, or upgraded to renewable natural gas.
The global biogas market revenue stood at $48.9 billion in 2024, with revenue forecasted to reach $51.9 billion in 2025 and beyond. This growth is driven in part by food manufacturers who have realized their waste stream represents untapped energy.
According to ReFED’s 2025 USA Food-Waste Forecast, anaerobic co-digestion systems that yield renewable natural gas now reach breakeven in under five years.The payback gets even better when you factor in multiple revenue streams: energy generation, tipping fees from accepting waste from other businesses, and sales of nutrient-rich digestate as fertilizer.
The United States currently has approximately 2,500 sites producing biogas in all 50 states, but the potential for growth is substantial, with over 17,000 new sites identified as viable for development. For food manufacturers with steady volumes of organic waste, partnering with an existing biogas facility or developing on-site digestion could make financial sense.
Composting: The Lower-Tech Revenue Option
Not every operation needs a multi-million dollar biogas system. Commercial composting operations provide a simpler option for food manufacturers looking to monetize organic waste while reducing disposal costs.
Many regions now have commercial composting facilities that accept food manufacturing waste. Instead of paying landfill tipping fees, manufacturers either pay lower fees to composting operations or, in some cases with high-quality organic waste, receive payment for materials that can be turned into premium compost products.
The economic advantage isn’t always in direct payment for materials. Often the savings come from reduced hauling costs, especially when manufacturers can consolidate waste streams and ship larger volumes less frequently. This is where equipment like balers for packaging waste and proper separation systems like turbo separators for organic materials become important.
Separation and Handling: The Foundation of Any Revenue Program
None of these landfill diversion opportunities work if your waste streams are contaminated or poorly managed. Mixed waste has minimal value and limited markets. Separated, consistent waste streams command better prices and have more buyers.
This means looking at your facility’s waste handling systems. Do you have separate collection points for different material types? Can operators easily segregate organic waste from packaging? Are materials stored properly before pickup to prevent contamination or spoilage?
For many food manufacturers, the first step toward turning waste into revenue is a thorough waste audit to understand exactly what’s being generated, where it’s coming from, and how it’s currently being handled. This baseline data helps identify which materials have the most revenue potential and what changes to separation or storage systems would be needed.
The Packaging Side of the Equation
While organic waste from food production gets a lot of attention, don’t overlook the packaging materials. Cardboard, plastics, and other packaging materials from incoming ingredients and shipping finished products represent another revenue stream.
Proper handling of these materials through equipment like balers can significantly reduce hauling costs while generating revenue from recyclable materials. The key is keeping these streams separate from organic waste to maintain material quality and value.
Getting Started: What Makes Sense for Your Operation
The right approach depends on several factors specific to your operation:
Volume and consistency: Higher, more predictable volumes open up more options and better economics.
Type of waste: Wet organics, dry byproducts, and packaging materials each have different optimal pathways.
Location: Proximity to rendering plants, feed mills, composting facilities, or biogas operations affects transportation costs and revenue potential.
Existing infrastructure: What separation, storage, and handling capabilities do you already have?
For some manufacturers, the answer is partnering with established processors or haulers who can handle the logistics. For larger operations with significant waste volumes, developing on-site processing or entering longer-term agreements with waste-to-energy facilities may make more sense.
The Bottom Line
Food manufacturing waste doesn’t have to be a cost center. With the right approach to separation, storage, and partnerships, what you used to pay to dispose of can become a source of revenue, but most importantly can support your sustainability goals.
The economics vary by operation, but the trend is clear. More food manufacturers are finding that their “waste” has value in animal feed markets, biogas production, composting operations, and recycling programs for packaging materials.
Whether you’re just starting to think about waste differently or looking to optimize an existing program, understanding your waste streams and their potential value is the first step.
