The Raízen Biogas Power Plant generates 21 MW of installed capacity, making it one of the largest biogas power plants in the world. Raízen, the plant owner and operator, utilizes vinasse (slop leftover from distillation) and filter cake (residue from sugar cane juice purification), both by-products from sugar cane processing by an adjacent sugar cane plant.
PENETRON ADMIX, a crystalline waterproofing admixture, was used to treat 4,000 m3 (5,000 yds3) of concrete for all the tanks, including the critical biogas tank. PENEBAR SW-55 swellable waterstop strips were used to seal the construction joints. PENETRON, a topical crystalline material, and PENECRETE MORTAR, were used to seal the tie-holes. PENETRON ARC, an innovative active mineral protective coating specifically formulated for anaerobic (and biogas) conditions, was topically applied to the gas zone of the biogas tank to protect the concrete from attack from sulfuric acid (H2SO4), a by-product of the biogas generation process.
