  • Using materials recovered from the waste stream typically results in less waste, pollution, and energy use than using virgin materials. From an environmental standpoint, post-consumer is typically considered preferable to pre-consumer recycled content because post-consumer recycled materials are more likely to have been diverted from landfills.

    In some cases, we consider products with recycled content green but with some caveats regarding where they should be used. For example, rubber flooring made from recycled automobile tires should not be used in most fully enclosed indoor spaces due to the likelihood of VOC emissions.

    Recycling can have downsides. For example, some studies show that curbside collection programs and some recycling processes use more energy than they save. Closed-loop recycling is generally preferable to “down-cycling,” in which a lower-grade material is produced—but due to contamination of waste streams and the difficulty of extracting high-value ingredients, down-cycling may be as good as it gets. At times recycling can re-introduce hazardous components. Some products, like copper and aluminum, include a high level of recycled content as a matter of course—which we applaud, but don’t consider justification for listing in GreenSpec. As more complete life-cycle information on recycled materials and processes becomes available, we use that to increase our scrutiny of recycled products.

  • Included here are various erosion-control products, foundation products that eliminate the need for excavation, and exterior stains that result in lower VOC emissions into the atmosphere. Fluorescent lamp and ballast recyclers and low-mercury fluorescent lamps reduce environmental impacts during maintenance and disposal of luminaires.

DeepRoot Green Infrastructure's impermeable geomembranes protect landscaping, hardscapes, and foundations against damage from underground water while also providing some protection against invasive species and roots. (For greater protection against roots, the company also makes dedicated root barrier products). DeepRoot’s geomembranes are made from a minimum 75% post-consumer recycled high-density polyethylene (HDPE) and are available in 300-foot rolls, in three thicknesses, and widths from 18" to 40".

Though polymer-based products dominate the erosion protection market, natural-fiber alternatives are often better options. The primary advantage of natural-fiber erosion control products is their biodegradability even after vegetation is established. Photodegradable products often fail to break down, as plant growth and other cover prevents light from hitting the material. And unlike polymer-based fabrics, natural-fiber products also absorb moisture and work like mulch, benefiting seedling establishment.

Natural-fiber options listed by GreenSpec include coir (coconut-husk fiber obtained from coconut oil production) and jute, a fiber commonly used to make twine.

Impermeable synthetic products can protect landscaping, sidewalks, and roads from damage from underground water flow. GreenSpec lists impermeable synthetic products engineered for underground use that contain a minimum 75% post-consumer recycled content.
