About Celtic Renewables
Celtic Renewables is a pioneering company in the green chemical sector, leveraging patented technology to convert low-value byproducts, residues, and waste into high-value green chemicals. These chemicals directly replace those made from gas and oil, significantly lowering the carbon footprint of everyday products such as skin creams, nail varnish, household cleaning products, paints, medicines, and vitamins. The company operates in the renewable energy and green chemical markets, serving clients who are looking to reduce their environmental impact and transition to more sustainable practices.
Celtic Renewables' business model revolves around its state-of-the-art biorefinery located in Grangemouth, which processes local byproducts and waste to produce bioacetone, biobutanol, and bioethanol. These green chemicals are sold to manufacturers looking to replace fossil-based chemicals in their products. The company generates revenue by selling these high-value green chemicals, which are in increasing demand as industries move towards sustainability.
The company is committed to driving the transition to a Net Zero, Nature Positive World through defossilisation, aiming to replace fossil fuel equivalents with sustainable, biologically derived green chemicals.
