Trumpler

Trumpler is a family-owned chemical company founded in 1868 in Worms, Germany, with subsidiaries in Spain, Italy, France, China, Brazil and Mexico. Its core business is the development and manufacture of chemical products for the leather industry, an activity that has given the group long-standing expertise in protein chemistry.

Trumpler’s plant biostimulant activity is based at its Spanish subsidiary, Trumpler Española (Barberà del Vallès, Barcelona), which manufactures protein hydrolysates for agriculture. These products are obtained by controlled enzymatic hydrolysis of collagen and contain free amino acids and peptides. They are formulated for foliar and fertigation applications and are supplied to customers in Europe and other international markets, both as finished products and as ingredients for other manufacturers.

The company’s research focuses on the characterisation of protein hydrolysates, the mode of action of collagen peptides in plants and the development of new formulations. Agronomic evaluation is carried out through greenhouse and field trials with universities and research institutes. The raw material is protein recovered from by-products of the leather and gelatine value chains, which links Trumpler’s biostimulant activity to the circular use of resources.

Trumpler contributes to the sector by supplying protein hydrolysates to biostimulant manufacturers and distributors and by generating technical knowledge on this category of products, including analytical characterisation (molecular weight distribution, amino acid profile) and agronomic data from independent trials. The company also engages with the regulatory framework for the use of materials derived from animal by-products in EU fertilising products under Regulation (EU) 2019/1009, an area relevant to the wider protein hydrolysate sector.
