Turning Brewery Waste into High-Value Proteins and Bio-Chemicals for Industrial Use

foodPilotedTRL 7

Imagine a brewery that doesn't just make beer, but acts like a mini-factory. Instead of throwing away leftover grains and gases, they use insects and tiny microbes to eat that waste. This process turns trash into valuable ingredients for pet food, cosmetics, and cleaning products.

The business problem

What needed solving

Breweries produce massive amounts of spent grain, wastewater, and greenhouse gases that are costly to manage and underutilized. These waste streams represent a lost revenue opportunity and a high carbon footprint.

The solution

What was built

A modular biorefinery pilot plant. It includes technical specifications for food safety equipment, heat/cold production, and electronic data collection for biomass valorization.

Who can put this to work

Animal Feed
any
Target: Pet food manufacturer

If you are a pet food manufacturer dealing with high costs of sustainable protein — this project developed a way to produce 13.5 tons/year of insect protein from 40 tons/year of spent grain that provides a circular alternative to traditional meat sources.

Cosmetics
SME
Target: Skincare product developer

If you are a skincare developer dealing with the need for sustainable active ingredients — this project developed a method to convert methane (CH4) into ectoine, a high-value ingredient for cosmetics.

Industrial Cleaning
mid-size
Target: Chemical disinfectant producer

If you are a disinfectant producer dealing with carbon-heavy production processes — this project developed a route to create a chlorine-based disinfectant from CO2 bioconversion, reducing the carbon footprint by 45%.

Frequently asked

Quick answers

What is the expected industrial scale of this technology?

The project aims for a large-scale implementation with the installation of 100 valorization plants across the EU within 5 years of commercialization.

How does this affect production costs and environmental overhead?

Based on available project data, the system achieves a minimum 45% carbon footprint reduction in each value chain, which can lower environmental taxes and improve sustainability ratings.

What is the IP or licensing status of the biological conversions?

Based on available project data, the project focuses on validating 5 key biological conversions at a demo-scale (TRL 7), but specific licensing terms are not provided.

How is the technology integrated into existing brewery operations?

It is designed as a modular solution where industries can select from 5 biotechnological routes to upgrade side-streams like bagasse, wastewater, CO2, and CH4.

What is the timeline for commercial availability?

The project runs until August 2026, with a goal of deploying 100 plants in the 5 years following commercialization.

Consortium

Who built it

The consortium is heavily industry-driven, with 9 industrial partners (69% of the total) and 7 SMEs. This high ratio of commercial entities, led by the brewery MAHOU SA, suggests a strong focus on market viability and practical application rather than pure academic research.
