Abstract: The present invention provides a flow-through photobioreactor containing at least one thermoplastic multi-wall sheet having an upper layer and a lower layer having arranged there between at least two sidewalls, at least one inner wall and two or more end caps. Also provided is a process for the production of a biofuel with the inventive photobioreactor. The photobioreactor and process of the present invention have the following advantages: genetically engineered microbes that give higher yields cannot escape into the environment, water in the system does not evaporate, no weeding (presence of unwanted algae), UV light from the sun is filtered out by the reactor walls, temperature control is possible, CO2 from power plants, breweries, etc. can be artificially fed to increase yield. The inventive photobioreactor is also less expensive to build than pipe reactors and may have low energy costs to operate, because little or no energy is needed for agitation and pumping in a preferred gravity assisted embodiment.

Abstract: A multilayer product characterized by its improved weatherability and mechanical properties is disclosed.
