From Leather to Protein Hydrolysates

Natural Biostimulants for a Stronger Agriculture

Valuing a natural resource for a more productive and sustainable future

  1. Leather (collagen)

    By-product of the food industry, a natural source of collagen.

  2. Extraction & transformation

    Collagen is extracted, purified and hydrolyzed into peptides and amino acids.

  3. Protein hydrolysates

    A rich mixture of amino acids and peptides with high bioavailability.

  4. Application in agriculture

    Supports plant development, increases nutrient uptake and stress tolerance.

  5. Stronger crops and higher yields

    Improves root development, plant quality and resilience to environmental stress.

  • Adds value to by-products

    Zero waste, more resources for the future

  • Circular economy

    From waste to value

  • More efficient agriculture

    Healthier plants, better crops

  • Lower environmental impact

    Less chemicals, more nature

Our approach

Nature supplies building blocks,
science unlocks them

  1. Collagen

    Natural raw material

    In fiber or gel form.

  2. Denaturation

    Thermal treatment

    Controlled thermal treatment to break down the triple-helix structure and sterilize the product.

  3. Chemical hydrolysis

    Chemical hydrolysis

    Controlled reaction

    Selected chemical agents under controlled pH, temperature and pressure fragment protein chains.

  4. Free amino acids & peptides

    Hydrolyzed protein

    Molecular weight: below 10,000 Dalton

    Smaller, stable molecules ready for agricultural, nutraceutical, cosmetic or industrial applications.

Discover our process

High-performance technology, certified quality.

  • Our production process is based on advanced controlled hydrolysis, delivering a consistently stable molecular weight below 10,000 Dalton.
  • The final product has a very low chromium level, ensuring maximum safety, sustainability, and compliance with international standards.
  • Every batch undergoes rigorous quality verification through an independent certified analysis laboratory, which provides complete chemical and microbiological reports. This guarantees full transparency and reliability for our partners.

A trusted B2B partner

  • We support companies across multiple sectors by supplying both finished products and raw materials, offering flexible solutions tailored to industrial needs.
  • Our approach combines technical expertise, consistent quality and the ability to scale production efficiently.

Built aroundthe plant’spriorities.

One technology, many harvests.

Benefits on plants

Benefits on plants
Root firstA stronger root system helps plants to access water and nutrients where it matters.
Stress resilienceAmino acids and peptides support crop vitality under stress conditions: heat and drought, cold and frost, soil salinity, phytotoxicity and transplant stress.
Nutrient use efficiencyAmino acids are effective complexing agents that stimulate nutrient uptake and translocation within the plant.
Crop qualityBalanced nutrition supports growth, fruit development and harvest quality.

Founded in 2005, AKEL LEATHER built its expertise in collagen from tanned bovine hides, before extending that production knowledge into circular bio-nutrition.

Committed to sustainability and minimizing waste, the company has produced animal-origin hydrolysed protein since 2010. Hydrolysed protein is a controlled mixture of free amino acids and low molecular weight peptides, available in both liquid and solid forms.

In 2020, AKEL relocated its operations to a 6,400 m² facility in the Bursa Leather Organized Industrial Zone. Its two production units—the tannery, specialising in split suede, and the liquid amino acid manufacturing plant—are both located within Bursa’s industrial area but operate as separate facilities.
