Calpech

Calpech S.L. is a dynamic spin‑off company founded in 2021 at the University of Alicante, Spain. Specializing in advanced environmental nanotechnologies, the firm has developed and patented a pioneering process to convert organic residues—particularly from olive‑oil production—into high‑value iron nanoparticles encapsulated in carbon.

Calpech’s core innovation lies in its proprietary Ce‑in additives, which enhance biogas production by up to 40 %, while significantly reducing harmful compounds such as hydrogen sulfide and sulfur dioxide during anaerobic digestion. These iron‑carbon nanoparticles not only stabilize digesters but also serve as nutrients for biogas‑producing microbes, improving both yield and gas quality.

Beyond biogas optimization, Calpech’s technology supports a broad range of environmental applications: odor remediation, removal of heavy metals from soil and water, elimination of pharmaceuticals and pesticides, and even use as a fertilizer—advancing principles of green chemistry, circular economy, and sustainable resource valorization.

Backed by a team of scientists and engineers with nearly three decades of research experience, Calpech has scaled from laboratory development to pilot and industrial output, delivering its solutions at a commercial level. In late 2024, BeAble Capital invested €600,000 in the firm, recognizing its deep‑tech potential and alignment with industrial decarbonization goals for Agenda 2030.

Calpech’s mission is to transform waste into resources through scientifically grounded innovation, while its vision is to become a global benchmark in nanotechnology applications for environmental sustainability. With an expanding client base using its Ce‑in products, the company continues to drive forward circular, scalable and sustainable industrial models.
