ETSA Group is a leading Portuguese rendering company specialized in the collection and valorisation of Category 3 animal by-products. Through an extensive collection network and industrial processing, ETSA transforms these materials into high-value, sustainable outputs – including proteins for animal nutrition.
More recently, ETSA launched ProHy, an innovative hydrolyzed protein produced via a proprietary natural hydrolysis process without chemical reagents, designed as a premium, highly digestible ingredient. ProHy is positioned as a versatile solution for animal feed formulations across species, with initial market focus on premium pet food, aquaculture, and veterinary applications.
ETSA’s footprint in animal feed also extends to marine proteins via its BARNA activity, producing feed-focused ingredients sourced from fishery by-products — supporting aquaculture and petfood nutrition solutions.
