Leather manufacturing process unavoidably generates significant amount of solid waste, which can be used as recycling resource or transported to the lanfill as a production waste. Processing of 7000 t of raw cattle hides per year leads to approximately 800 t of lime fleshing generation. To avoid transportation of this waste to the landfill, the company introduced technology for lime fleshing recycling into fodder and industrial fat.  


Amount of lime fleshing as solid waste decreased by 800 t/ year. Total investment - 14500 EUR, pay-back period - 2.1 years.

Innovative aspects (ecologic, social and economic)

The innovation enables significant reduction of solid waste, and improved environmental situation in the region by decreasing soil, water and air contamination. The innovation is also benefitial for the company in terms of economic aspects with anual project savings of 70 000 EUR/ year.
