Brewery Sustainability Goals
- Reducing CO₂ Emissions and Usage
One of our primary goals is to significantly reduce our carbon emissions across all areas of production. We aim to lower our reliance on traditional fuel sources and to cut down on the CO₂ released during brewing and related processes.
Furthermore, we are actively exploring systems for CO₂ capture and reuse, particularly the recovery of CO₂ produced during fermentation for reuse in carbonation and packaging. This not only reduces emissions but also decreases the need for externally sourced CO₂, which is often energy-intensive to produce and transport. - High Efficiency Boiler upgrade Upgrading old ineffecient equipment to more efficient technology that uses less resources and produces more steam energy quicker leading to higher efficiency in the brewing process.
- Spent Grain Repurposing
We currently repurpose 100% of our spent grain by supplying it to local farmers. This byproduct of the brewing process is rich in nutrients and serves as an excellent livestock feed. This initiative minimizes waste, reduces methane emissions from decomposition in landfills, and supports the local agricultural community, reinforcing our commitment to a circular economy. - Transition to Renewable Energy
Hemingway’s Brewery is committed to a long-term goal of transitioning to solar energy to power brewing operations. This is currently under feasibility assessment, and early-stage planning is underway to determine optimal system size, integration methods, and potential energy storage solutions. The move to solar power would drastically cut our reliance on fossil fuels and further decrease our operational carbon footprint.
High-Efficiency Boiler Installation
Investment in a new, energy-efficient boiler system.
Project Objectives & Technical Benefits
- Enhanced Fuel Efficiency:
The new boiler is designed with advanced heat exchange technology and control systems, allowing for more precise temperature management and reduced heat loss. Compared to our current unit, the new boiler will achieve significantly higher thermal efficiency, resulting in lower fuel consumption for the same brewing output. - Reduced Greenhouse Gas Emissions:
By consuming less fuel, the boiler will generate fewer CO₂ emissions per batch brewed. This directly contributes to our carbon reduction targets and lowers our environmental impact. - Improved Process Reliability and Lifecycle Sustainability:
The system’s improved design also means fewer mechanical breakdowns and longer intervals between maintenance, reducing downtime and material waste from replacement parts. - Scalability and Integration Readiness:
The new boiler is designed with future sustainability upgrades in mind. It is compatible with potential solar thermal integration or supplementary renewable heat sources, making it a flexible foundation for the next phase of our clean energy transition.
Alignment with Business Sustainability Goals
The new boiler project aligns with Hemingway’s Brewery’s sustainability goals in several critical ways:
- Directly reduces CO₂ emissions through higher efficiency and lower fuel use.
- Lowers operating costs, making our sustainable practices financially viable and scalable.
- Enables future CO₂ recovery technologies by stabilizing fermentation and conditioning temperatures, which are key to efficient gas capture.
- Supports community partnerships by maintaining operational consistency, which allows for continued supply of spent grain to local farms.
- Lays the groundwork for renewable energy adoption, through improved thermal system compatibility.
