Cutting Energy and Carbon In The UK Bakery Industry

Carbon trust and Food industry leaders  of  UK  are joining hands go reduce energy  and carbon emission through grants and support

 Baking bread in lighter tins, cleaning pipes with ice instead of hot water, and using microwaves to dry fruit gums and jellies: these are just some of the ideas being explored by the Carbon Trust and food industry leaders to cut energy use and carbon emissions at UK manufacturing sites.In commercial bakeries, reducing the weight of baking tins, improving the efficiency of ovens and recycling waste heat could together cut the sector’s emissions by around 9%.


Over the last year, the Carbon Trust has worked with companies including Allied Bakeries, Dairy Crest, Cadbury and Nestle to identify more energy efficient manufacturing processes with the potential to cut industry carbon emissions by some 450,000 tonnes a year: equivalent to taking more than 150,000 cars off the road.

Now, in partnerships with the Food & Drink Federation and Dairy UK, the Carbon Trust has challenged food producers and equipment suppliers to help prove the business case for these new processes. It is offering co-funding of up to £250,000 per project and in exceptional instances up to £500,000.

The challenge comes as part of the Carbon Trust’s Industrial Energy Efficiency Accelerator (IEEA) – a £15m programme aimed at catalysing low carbon innovation in industry.

“The way to make truly substantial cuts is to get to the very heart of manufacturing. We want to work with manufacturers to rethink production processes from the ground up. Innovation is the backbone of the low carbon industrial revolution that will not only reduce emissions but will also generate jobs and cut costs,” explains said Benj Sykes, director of innovations at the Carbon Trust.

Indian Bakeries Opting For Solar Energy

With  cost of  fuel and power   increasing day by day  Indian bakeries  are looking for alternative  energy  solutions to cut down their fuel as well as electric energy  cost . Fuels used in bakeries are LDO /HSD/CNG/LPG/Furnace Oil /Electricity .

All bakeries requires hot water to clean the utensils used in production process as fat is a major ingredients in bakery product .Utilities run on these fuel  for  heating water  are  Hot water generators , Boilers or Hot water geysers .  Even at large bakeries the employees canteen consumes large amount of  hot water for  utensil cleaning . Solar water heating  gives these bakery an alternative source energy  for heating water and  reducing cost of fuel .Temperature attained for such applications could be between 55deg C - 60 deg C

The payback period for such investment  could be something between 18 -24 months depending upon the consumption .Many companies like Britannia has installed solar water heating  system  for its  hot water requirement .The most popular supplier of such system is  Tata -BP  Solar India Ltd .

Other application for usage of  solar energy  for the larger bakeries have been  the  lighting   around  the factory  through photo voltaic s cells .

Major advantage of solar energy are

• Lower maintenance cost 
• Clean environment 
• Available in abundance  all around the year excepts for some region 
• Save energy cost  by reducing either fuel or electricity cost . 
• No storage space required for  fuel .No logistics 

Here is a line diagram for  such arrangement
