Mill Green Brewery is situated behind the traditional White Horse Inn at Edwardstone on the footprint of a derelict stable. The object from the start was to build a new business that was going to have minimal environmental impact including the building itself and the production process, raw material sourcing and distribution. The building needed space for raw material storage, office, brewing, bottling and casking and an insulated conditioning room.
The original concrete floor was incorporated in the new foundations and no concrete was used in the entire building, only lime. The structure was wood rather than steel. All wall bricks were reused and new floor bricks came from local brick maker with onsite clay. No hard conventional plaster or plasterboard was used, only lime plaster on waste woodchip board and bare clay board. The building is clad in wooden weather boarding.
All insulation is lambs wool.
All lighting low energy.
Solar Hot Water Heating
Solar panels 25 sq m on the roof generating an average daily absorbed energy in the summer of 80kwh, costing around £8,000.
Wood boiler with 210 lt furnace generating 50 k/w. Cost £20k.
Waste materials from the brewing process are used as follows; brewers grains to local Red Poll cattle, hops are used as compost/mulch, waste beer will hopefully be used for vinegar production.
The design was for a Suffolk Barn type building to fit into a rural environment. Our objective was to cause minimum environmental damage in the building of and running of our business. Planning did cause some problems but for technical reasons not related to construction or renewable use.
No grants were available at the time.
We are at the beginning of a long learning process to hopefully be able to brew by using only our own renewable energy. The carbon footprint of our raw materials supply is now being addressed.
The project has so far been very successful but now that we have developed a really good range of traditional ales, the emphasis will be on increasing production and squeezing the maximum out of our renewable energy supply, including conserving and recycling heat. If we were to start again I would not have the brick floor, it looks good but cleaning is difficult. With more money we could have had a pressurised steam heating system for boiling the wort saving a large amount of energy.
