4.2 Benefits
Serengeti breweries Limited started RECP implementation in 2011 after receiving training from the CPCT. Implementation of several RECP options in energy management such as; switching off lights during the day time; control of ACs usage; replacement of 30kW air compressors by 7.5kW air compressor when there is no production and replacement of steam condensate traps have enabled the company to achieve a significant reduction in energy consumption which resulted into an annual saving of USD 284,000. Also the company was able to save USD 7200 through implementing water management options like using ETP water for gardening, installation of push taps for the urinals in men toilets, training of employees on proper use of water and re using of backwash water in toilets.
RECP concept also has complimented the construction of Effluent Treatment Plant (ETP) at the factory that improved the quality of waste water generated and hence attaining the environmental compliance. Initially the company was spending about Tshs 300 – 400 million per month (equivalent to USD 300,000 per year) for disposal (collection and transportation) of wastewater to Municipal wastewater treatment facilities. The construction of ETP within the industry premises has eliminated this cost.
Likewise, air emissions have also been reduced by 19% as a result of reduction in the use of fossil fuels and good production plan i.e. use of small machines when producing less. The company participated in the 2013 National RECP Awards competition and won in the categories of Waste Water Management and Water Use Management as first runner-up and second runner-up respectively.

6.6 ApproachTaken
In 2010, TBL realized the importance of adopting RECP concept in order to acquire potential techniques and approach on how to handle water usage, energy and materials consumption more efficiently and reduce air emissions and waste generation.
In collaboration with the CPCT, the company started implementing RECP by first training two key staff in RECP concept, its implementation and benefits. The two trained staff formed a RECP team which comprised 10 members drawn from various sections/departments. The main task of the RECP team was to analyze the present operational status in terms of resource (water, energy and materials) consumption by conducting waste and lose analysis and mass balance using the RECP toolkit.
After realizing the benefits of RECP, the company decided to dedicate some funds for the implementation of RECP projects and established a special task force called Sustainable Development Team to strategically oversee the activities of the RECP team.
6.7 BusinessCase
Achievements obtained from the implementation of RECP have enabled the company to improve its operations by increasing its resource productivity, getting high quality products and reducing pollution load. The benefits realized by implementing RECP options have made the company more competitive in business, and have enabled it enhance its Corporate Social Responsibility contribution, environmental compliance and overall image in the community.
