Pre-consumer (also called “post-industrial”) recycling refers to the reuse of industrial by-products, as distinguished from material that has been in consumer use. The iron-ore slag used to make mineral wool insulation and the fly ash used to make concrete are examples of post-industrial recycled materials. While post-consumer recycled content is preferable, a product that uses pre-consumer content or recycles a seldom-used waste product, especially in an area where recycled products are hard to find, can be considered green.
Excluded from this category, by FTC definitions, is the use of scrap within the same manufacturing process from which it was generated—material that would typically have gone back into the manufacturing process anyway.

Some products help us use other products or materials more efficiently. For example, drywall clips allow the elimination of corner studs, engineered stair stringers reduce lumber waste, and concrete pigments and polishing systems can turn concrete slabs into attractive finished floors. We also recognize some products, like vacuum plumbing systems, which use less material than their conventional counterparts. Many products with this attribute are fairly unique, so we bring a skeptical eye to manufacturer claims, but not a specific standard.

Just how low the VOC level needs to be for a given product to qualify for inclusion in GreenSpec depends on the product category. For most products, we require certification to California’s health-based emissions standard, CDPH Std Method v1.1 standard (also referred to as California Section 01350), which tests a product’s resultant VOC concentrations in the space after a given period of time. For wet-applied products like paints, caulks, and adhesives, we still also look for VOC content instead of, or in addition to, verified low emissions; this is because emissions testing doesn’t adequately test initial offgassing, and VOC content is currently the only widely available proxy.
Knoll offers Antenna Workspaces system furniture, a flexible line of office components, allowing one set of furniture to be reconfigured for many uses over its lifetime. Antenna incorporates tables—which can be configured as desks—wood or metal storage units, and screens to accommodate groups or individuals. Antenna work surfaces use a simple design with one-inch square steel legs supporting a wood, laminate, or glass tabletop. Desk and table extensions provide opportunities for collaborative work within clustered office areas. Antenna tables can be configured to create a “Big Table” for collaborative work or meetings. Antenna workspaces contains no fiberglass or PVC and is manufactured with FSC-certified components.
As with all furniture products, make sure that office furniture doesn’t introduce harmful emissions into the space. Also look for lower-impact materials and manufacturing processes.
Office Furniture must meet the same high bar that GreenSpec has established for all furniture products: products must be low-emitting and exhibit multiple other environmental features, such as being made primarily from greener materials.
The greenest product is often one that has already served one useful life. Where feasible, reusing or refurbishing existing furniture or selling it for reuse can save both financial and environmental resources. Sources for office furniture that is remanufactured or refurbished exist in most major cities. Salvaged products frequently don't have low-emitting certifications—check the certifications to be sure.

Modular, flexible, integrated interior architecture for office partitions and cubicles that incorporate such features as access flooring, walls, wiring and cabling, and lighting, can decrease building and remodeling time significantly.
