Visit Raven at the Algae Biomass Summit | October 14th-17th in Woodland, Texas


We are teaming up with MicroBio Engineering to display the latest in algae pond solutions. We will be featuring some of our popular algae pond liners including flexible CSPE M-Series and our rugged string-reinforced N-Series geomembranes. Raven Engineered Films acquired Colorado Lining International (CLI) in 2017, and CLI has been a leading force for over two decades in developing unique membrane liners and related technologies for algae production and support ponds. We understand the economic and design challenges of algae biomass production are constantly working to develop the most cost-effective high value alternatives. CLI had successfully introduced several targeted polymers for algae raceway® ponds, along with the latest fabrication and installation techniques used all over the world. We manufacture and provide the widest range and selection of geomembrane lining materials and have produced millions of square feet for algae applications.

In a partnership formed by CLI and MicroBio Engineering; they developed the world’s first large-scale algae pond system in an easy to use kit format. APIAC® systems are Algae Raceway® kits designed to provide high performance pond systems that are assembled from premium grade materials and structured at an affordable price point. APIAC® systems are all inclusive and require minimal planning and resources to complete. The APIAC® systems are marketed as Algae Raceway® kits and are sold exclusively by MicroBio Engineering, Inc.

CSPE M-Series (36-90 mil)—Chlorosulfonated polyethylene reinforced flexible geomembranes provide an exceptional service life. M-Series is a synthetic rubber product manufactured through a calendaring process into plies over a reinforcing polyester scrim layer. The M-Series is available in 3-ply layers and 5-ply layers with up to two reinforcing layers. M-Series materials are available in varying styles, colors, plies, thickness, supporting scrim types, and come with up to a 30-year weathering warranty for approved CSPE applications. In terms of durability, ease to install, long-term performance, and customer satisfaction CSPE M-Series geomembranes are the gold standard for Algae pond lining systems.

Dura♦Skrim® N-Series (30-45 mil)—Heavy-duty scrim-reinforced flexible geomembranes, reinforced with a close knit 9x9, 1000-denier polyester and fully encapsulated in a highly UV stabilized linear low-density polyethylene. Exceptional toughness and a highly stabilized formulation provide excellent protection for long-term exposed applications. N-Series geomembranes are certified under NSF/ANSI Standard 61, Drinking Water System Components - Health Effects, and also meet the physical property values as stated in GRI-GM25 Standard Specifications. N-Series scrim reinforced (LLDPE) otherwise known as Reinforced Polyethylene (RPE) will vastly improve dimensional stability for successful use in earthen raceway ponds.
