The scale of food waste is staggering, and its costs are immense. The food waste market is not a market in the traditional sense (where waste is a commodity), but rather the economic activity generated by managing and preventing food waste. This includes collection, treatment, and valorization services. The food waste market is driven by the recognition that waste represents lost resources—water, land, labor, energy—and generates greenhouse gas emissions. As the world seeks to feed a growing population sustainably, the food waste market is critical.
The broader food waste management market is the operational side. The food waste market for "prevention" is the highest priority. This includes technologies and services to reduce waste at source: inventory management software, demand forecasting, "ugly produce" marketing, and portion control. The food waste market for "donation" (redirecting surplus food to food banks) is supported by liability protections (e.g., the Bill Emerson Good Samaritan Act in the US). The food waste market for "upcycling" (turning surplus ingredients into new products) is growing.
The food waste market for "treatment" includes the technologies mentioned earlier (AD, composting). The food waste market for "valorization" extracts value from waste streams. The food waste market for "insect farming" (using food waste to feed black soldier fly larvae, which become protein for animal feed) is an emerging sector. The food waste market for "bioplastics" (using food waste as a feedstock) is also developing. The food waste market for "nutrient recovery" (extracting phosphorus from digestate) is a niche.
The food waste market is segmented by supply chain stage. The food waste market for "agricultural" waste (produce left in the field due to cosmetic standards) is significant. The food waste market for "manufacturing" waste (trimming, off-cuts) is often used for animal feed. The food waste market for "retail" waste (expired or unsold products) is often donated or composted. The food waste market for "household" waste is the largest and most diverse.
Looking ahead, the food waste market will see the adoption of "digital" tools for waste tracking. The food waste market for "traceability" will allow companies to identify hotspots. The food waste market for "cradle-to-cradle" certification (where waste is designed out) will become more common. As carbon pricing expands, the food waste market for "avoided emissions" credits will create a new revenue stream for waste diversion projects.
