- (57) Abstract
Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) or other materials are processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, in a vault in which the walls and optionally the ceiling include discrete units. Such vaults are re-configurable.

Description
Many potential lignocellulosic feedstocks are available today, including agricultural residues, woody biomass, municipal waste, oilseeds/cakes and seaweed, to name a few. At present, these materials are often under-utilized, being used, for example, as animal feed, biocompost materials, burned in a co-generation facility or even landfilled. Lignocellulosic biomass includes crystalline cellulose fibrils embedded in a hemicellulose matrix, surrounded by lignin. This produces a compact matrix that is difficult to access by enzymes and other chemical, biochemical and/or biological processes. Cellulosic biomass materials (e.g., biomass material from which the lignin has been removed) is more accessible to enzymes and other conversion processes, but even so, naturally-occurring cellulosic materials often have low yields (relative to theoretical yields) when contacted with hydrolyzing enzymes. Lignocellulosic biomass is even more recalcitrant to enzyme attack. Furthermore, each type of lignocellulosic biomass has its own specific composition of cellulose, hemicellulose and lignin.
Generally, the inventions related to enclosures for treating materials, such as biomass. The inventions also relate to equipment, methods and systems for producing products from materials, such as a biomass material. Increasing the throughput and safety, and reducing the costs associated with treatment of biomass are important goals in the development of useful and flexible manufacturing processes. In methods involving irradiation, hazards can be mitigated by enclosing the irradiation in a vault.
