	abstract = {In order for dairy farms to produce high quality milk, it is customary to clean the milking system using chemicals and a large volume of water after each milking. The dairy industry is a key part of agriculture in the Maritimes and is facing increasing concerns on impacts to the environment. Producers are faced with meeting environmental guidelines and ensuring proper handling and treatment of waste products. This study used a unique pilot milking system to test alternative wash practices while following the standard cleaning cycles to conserve water, chemicals and energy. The alternative methods included: recycling of the detergent and acid solutions and the reuse of wash solutions for multiple cycles. The recycle method reduced total water use by 45\%, chemical use by 64\% and energy use by 48\%. The reuse method reduced total water use by 45\%, and energy use by 45\%. This will result in a cost saving to the farms and less waste produced to be treated or released to the environment. The evaluation procedure included: collecting and analysing milk samples for bacterial counts, and inner pipeline surface measurements of bacterial counts and ATP levels. Testing was done at the beginning, midpoint and endpoint of the pipeline, so an entire pipeline surface analysis of the alternative cleaning methods could be carried out. The alternative wash strategies (Recycle and Reuse) showed no significant difference in sanitation levels when compared to the standard wash practices. This showed promise for the reduction of washwater generated from the cleaning of pipeline milkings systems. Which inturn will lower the environmental impact from the dairy industry.},
