Emergency Burn Ban In Effect 10/26/24 - An emergency burn ban is now in effect for all Connecticut State Parks, Forests, and Wildlife Management areas, prohibiting the use of all outdoor grills, firepits, and campfires, and the kindling and use of flame outdoors. DEEP and local agencies are working to contain several active fires across the state. Please avoid all affected State Parks and Forests, as well as the blue-blazed Mattabesett Trail. The Enduro Trail in Voluntown and portions of North Stonington within the Pachaug State Forest are closed at this time. Please note that today's forest fire danger report remains at an 'extreme' level. More information about the current fire danger, burn ban and recommended safety measures can be found here

Sustainable Breweries and Other Craft Beverages

“Environmental stewardship is paramount for the health and vitality of the craft brewing community” - John Stier, National Brewers Association website.

Connecticut's craft beverage industry, including breweries, wineries, distilleries, and cideries, has grown rapidly in the past 10 years with over 200 craft beverage manufacturers operating statewide in 2024. The brewing process is energy intensive, uses large amounts of water and generates high volumes of wastewater and organic wastes. There are many actions breweries and other craft beverage makers can take to reduce their environmental footprint, prevent pollution, conserve natural resources and be a model of sustainability.  The CT Department of Energy and Environmental Protection is committed to providing assistance to breweries across the state to minimize waste, reduce pollution, promote energy efficiency resulting in lower greenhouse gas emissions, and encourage use of less toxic cleaning products. For more information, contact Connie.Mendolia@ct.gov (860-424-3243) or DEEP.PollutionPrevention@ct.gov.

 

NEW FUNDING OPPORTUNITY for Craft Beverage Manufacturers in Connecticut for Projects that Prevent Pollution – Opens October 3, 2024:

Craft beverage manufacturers in CT are eligible to apply for a small grant to off-set the cost of equipment that can result in reducing pollution and increasing efficiency.

Recognition Program & Technical Assistance

Logo BetterBev Recognition

BetterBev New England  - Environmentally Sustainable Craft Beverage Program

Participate in this new, voluntary program and receive assistance with and recognition for operating in an environmentally sustainable way! 

This is a free program developed to help craft beverage manufacturers reduce their environmental impact by taking actions to minimize waste and the use of toxic products, and to manage resources efficiently. CT DEEP's Pollution Prevention program (P2) manages the program with input from the CT Brewers Guild.  Contact Connie Mendolia for more information.

Connecticut has collaborated with New Hampshire, Maine, Rhode Island and Massachusetts to develop performance standards and create this program; the New England states have similar programs that provide a consistent set of program criteria.  Find out more about the regional program at BetterBev .

Less Toxic Cleaning & Sanitizing

NEW OFFERING!  Free Assistance with choosing Safer Chemicals - includes review of products currently being used, bench-testing alternative products on your problematic soils, and performance testing. Find out more here 

Most breweries and other craft beverage makers are using chemicals common in food applications for cleaning- and sanitizing-in-place. There are safer options than caustic sodium hydroxide. The Toxic Reduction Institute (UMass Lowell) provides information for craft brewers on safer alternatives, including using brewers wash at a lower temperature and volume to clean and using NADCC tablets to sanitize:

Water and Wastewater Discharge

Wastewater discharges are regulated by CT DEEP and the local wastewater treatment facility (POTW). Beer making uses a significant amount of water and generates large amounts of high strength wastewater. It is important that breweries adhere to effluent limits set out in their general permits. Breweries can implement best management practices to reduce their high strength waste before sending to the treatment facility.  Assistance from DEEP's Pollution Prevention program is available at 860-424-3297 or email.

  • NEW! CASE STUDIES ON REDUCING WASTEWATER POLLUTION AT LOCAL CONNECTICUT CRAFT BREWERIES

    Three Connecticut breweries participated in a voluntary wastewater sampling project and implemented low and no cost best practices.  As a result, the breweries reduced BOD, COD and other pollutants being discharged or were able to identify how brewing processes contribute to discharge strength. Recommendations and actions taken by these breweries serve as a model for actions other local breweries can also implement.
  • DIY Trub Filtration - 3 minute video on how to eliminate solids from going down the drain using a super sack grain bag and a plastic drum which can be replicated anywhere. Watch this no-cost / low-cost brewing innovation created by the New England Environmental Finance Center 

  • DEEP's webpage on Water Discharge Permits and General Permits provides information on permits and general permits.  Scroll down to the lower half of the page to the light blue "General Permits" heading and below you'll find links to the permit applications and fact sheets. Craft breweries that discharge greater than 1000 gallons a day (gpd) of wastewater to a sanitary sewer system on any day or craft breweries that transport any amount of wastewater to a sewage treatment plant will need to submit a Notification Form under the Miscellaneous Industrial Users GP. Only breweries that discharge greater than 25,000 gpd or have been deemed a Significant Industrial User by the DEEP Commissioner will need to register under the Significant Industrial Users GP. 

Energy Efficiency and Renewable Energy

Onsite Assistance and Assessments:

1.  CT DEEP is working with UI and Eversource to assist breweries with reducing energy use and saving money.

  • The Small Business Energy Advantage program can provide free onsite audits by an approved vendor to identify opportunities for savings. This program program can cover a wide range of opportunities, including refrigeration, heating and cooling, ventilation, weatherization, and of course lighting using 0% on bill financing. 
  • Other Commercial and Industrial efficiency programs may also be available, including the Energy Conscious Blueprint program for new or existing breweries that are undergoing major renovations. 

2.  The new Southern New England Industrial Assessment Center (IAC) at UConn & University of New Haven administered by the US DOE was established in 2021. The IAC provides uses engineering students to provide free audits and consulting services to small and medium-sized manufacturers for saving energy, reducing water usage, reducing carbon footprint, adopting renewable energy, and improving productivity.  Breweries with energy bills greater than $100,000 may be eligible and can request an assessment here.

Reducing Waste, Waste & Organics Recycling

The brewing process generates a variety of wastes, including spent grains, spent yeast and tank bottoms. Separating out and collecting each waste steam allows them to be sent to an appropriate facility for reuse or disposal. Other wastes that breweries may generate include packaging, mandatory recyclables and scrap plate waste from dining, all of which can be diverted from trash. CT DEEP can provide assistance with setting up a program, including a site visit. Contact Connie Mendolia 

  • Free assistance with reducing waste: The Center for EcoTechnology (CET) can help you save money and integrate sustainable practices into your brewery and/or brewpub. With support from CT DEEP, CET offers easy, practical solutions to CT businesses at no-cost. A CET waste reduction expert will meet with you and provide custom recommendations to help you identify more beneficial uses for your surplus and waste. Contact reducewastect@cetonline.org, 888-410-3827, or click here to learn more or get started. Check out Apponaug Brewery Case Study, Warwick, RI.
