Introduction to
CITIGATE, S.L.

CITIGATE S.L. transforms by-products into new raw materials for green energy. By doing so, we support the circular economy, the energy transition, and efforts to combat climate change. Since 2004, we have been a leader in the European Union's movement toward more responsible business practices by creating value from recycling and upcycling residual products.

CITIGATE S.L. is an end-to-end service provider for liquid, fat and agro products. Only a handful of companies offer a similarly comprehensive range of services. Our aim is to fully unburden our clients/producers regarding liquid and fat products (ADR and non-ADR). CITIGATE distinguishes itself in terms of quality, consistency, and safety by simply delivering what we promise. This is something we’ve been doing for the last over 22 years!

We help companies increase profitability and generate new revenue streams by developing derivative products, minimizing waste, and implementing sustainable practices. Our diverse range of services includes trading, collection, and complete outsourcing of by-product management. This allows our partners to focus on their core business activities with confidence, knowing that their operational priorities will be met. By collaborating with us, our partners contribute to the circular economy.

We are continually researching various by-products to enhance renewable energy production while minimizing adverse impacts on humans and the environment. CITIGATE's business model combines competitiveness and sustainability, respecting both people and the environment.

Our Services

We collect waste and by-product materials from the animal agriculture, food, and pharmaceutical industries. This helps these industries become more sustainable by providing an alternative to landfilling and incineration.

1. Collect & Transport

We separate materials into fats and proteins, if necessary, and transport them to the appropriate endpoint, typically to biogas plants, central heating stations, biodiesel plants, or oleochemical facilities.

2. Create Value

Finally, the highest value is derived from the fats and proteins extracted, which are used to fuel the world with sustainable, low-carbon energy and high-grade feed materials.

3. Our Core Values

  • Integrity: Honesty, ethical, and openness.
  • Transparency: Authentic and straightforward in business.
  • Entrepreneurship: Knowledge, passion, and determination.
