Meeting water and energy challenges in agri-food sector with technology

Published on by

Worldwide, the overall growth in demand for agricultural products will require a 140% increase (pdf) in the supply of water over the next 20 years compared to the past 20 years. While the bulk of this demand will be from irrigation, food processing plants can also be water intensive. So, any technological innovations in the industry that save water are welcome. One such innovation is by Mars Petcare , which has developed a recirculation system that reduces the potable water used for cooling in its pet food production process by 95%. Wastewater is also down by 95% and gas by 35% through the use of a treatment method that keeps the water microbiologically stable. http://www.theguardian.com/sustainable-business/water-energy-challenges-agrifood-technology
