Water Usage & Recycling

According to the United Nations, the “demand for water is rising owing to rapid population growth, urbanisation and increasing water needs from agriculture, industry, and energy sectors.” In support of the United Nations SDG 6: Clean water and sanitation, Carib Brewery (Grenada) Limited has committed to reducing the quantity of water utilised in its operations and to continue providing key products and services for the purification, conservation, and reuse of water.

Water is involved in almost every aspect of the beer manufacturing process; as an ingredient, for cooling and extensive cleaning required to maintain the high hygiene standards in the food and beverage industry.

Our water preservation strategy is focused on improving water efficiency, water conservation, and managing wastewater.

A Circular Economy is one that reduces material use, is designed to be less resource intensive, and utilises waste as a resource to manufacture new materials and products.

One of the primary platforms for sustainability is Carib Brewery (Grenada) Limited's returnable bottle and crate system. The model ensures that bottles are collected and returned for reuse or recycling. By reusing bottles and crates, the consumption of raw materials used, and the energy required to produce them are reduced. The result is a significantly reduced carbon footprint. Increase primary packaging returns for reuse/recycling

To achieve this, a robust education campaign will be rolled out, to sensitise consumers on the returnable bottle and crate system and promote the benefits of reuse and recycling. In addition to this, more accessible locations for consumers and customers to return and recycle our main packaging items are currently under review.

Brewing produces a lot of spent malt grain and at CBG, spent grain is distributed to farmers free of cost as an additive to supplement animal feed. This spent grain has a high protein content which can reduce feed purchases by more than 30 percent. This initiative reduces the waste output of the process.

The upgraded Group Human Resource Information System (HRIS) and Payroll System, will move many paper-based processes to an electronic system, saving paper used for HR approval processes. This transformational project will facilitate the automation of manual processes, leading to greater efficiencies and empowerment of employees and managers.

Carib Brewery (Grenada) Limited installed a more sustainable beer filtration system. This membrane filtration system reduces the materials required for filtration by moving away from a Diatomaceous Earth (D.E.) coated stainless steel plate system.

As much as 1,500 kg of filter aid were used on average per month. The new filtration system eliminates the need for D.E., hence less materials required for the process and less solid waste output. An added benefit of this system is the enhanced beer quality for consumers.

Increase the volume of CO2 recovered annually

At CBG, the CO2 generated during fermentation is a valuable resource that can be recovered, purified, and reused within the brewery operations. As well as helping to reduce production costs, CO2 recovery from fermentation means a greener process overall, with lower emissions and a reduced carbon footprint. Carib Brewery (Grenada) Limited will be installing a recovery system in 2023.
