Water footprint

Abstract

Sustainability of water use has got into focus recently, as availability of fresh water resources is under depletion. Population growth, extreme weather conditions (drought), increasing global meat demand all results in higher water consumption of humanity and ecosystem. Water footprint is a promising indicator, which assesses both qualitative and quantitative deterioration of fresh water supplies. By identifying blue, green and grey water components, water use can be assessed in a more comprehensive way. Furthermore impact assessment of different components during production and processing let us identify crucial points of water use, where more efficient solution should be found. As a consequence of a more conscious and sustainable water use assessment considering water footprint, there is a chance, that future generations will inherit fresh water supplies at least in the same condition as we got it from our ancestors.

Treatment of livestock slaughterhouse wastewater by the electrochemical method using stainless steel and copper electrodes

“…Unfortunately, meat processing is also associated with high consumption of fresh water that in turn generates huge volumes of wastewater (Fresán et al, 2019). The trend is also projected to grow with time as the population keeps on increas-ing (Nagypál et al, 2019). The effluents generated from the livestock slaughterhouses are globally recognized as harmful (Bustillo-Lecompte total organic carbon (TOC), total phosphorus (TP), and total suspended solids (TSS) (Amin et al, 2016).…”

The trend is also projected to grow with time as the population keeps on increasing (Nagypál et al., 2019). The effluents generated from the livestock slaughterhouses are globally recognized as harmful (Bustillo‐Lecompte & Mehrvar, 2017), due to the complex composition of pollutants including fats, proteins, fibers, high organic content, pathogens, as well as pharmaceuticals resulting from veterinary activities.…”
