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.

Stormwater runoff from the built environment, often mixed with contaminants, has a damaging effect on local and downstream ecosystems. Porous paving products and vegetated roofing systems result in less rainwater runoff and thereby reduce surface water pollution. Stormwater treatment systems reduce pollutant levels in any water that is released. Again, quantifiable benefit and a strong track record are important determinants here of “green.”

Looking beyond the walls of a building, many products can contribute to safer neighborhoods, improved walkability and making high-density communities more appealing. We look for innovative products that support the greening of public spaces, facilitate high-density development, make alternatives to automobile transit more feasible, or otherwise contribute to the quality of outdoor spaces.
Colbond, which has more providing green roofing products for more than 25 years, now offers Enkamat root reinforcement, and EnkaRetain & Drain and Enkadrain for water retention and drainage. Enkamat anchors roots and holds growing medium, making it appropriate for sloped roofs or high-wind conditions, while Enkadrain is made from 40% pre-consumer recycled polypropylene and contains a waterproofing membrane. The company’s EnkaRetain & Drain has a water retention fabric that holds ten times its weight in water, according to the company, allowing excess to flow through. It is flexible—making it easier to shape—and it doesn’t require an aggregate drainage layer, reducing the load on the roof.
07 55 63: Green Roof Systems
Green roof systems, used primarily for low-slope roofs, can protect the roof membrane, help green the built environment through rooftop plantings, and reduce stormwater runoff. By detaining over 50% of rainwater from a typical storm, green roofs help reduce the loads placed on storm sewers, making them a particularly attractive system in urban areas that have combined sewer overflow (CSO) events during heavy rains.
Extensive green roofs are low profile and relatively lightweight, using planting media that is less than six inches deep. They are not meant for foot traffic and require drought-tolerant plants and grasses.
Intensive systems are larger systems used in commercial applications that can be sized to incorporate plants ranging from grasses to trees. These systems can incorporate walkways and may use more than seven layers of material—including growing medium, filtration, geotextile barriers, and waterproofing—to provide proper drainage and roof protection from moisture and roots. Many green roofs are custom designed and can be a combination of intensive and extensive systems.
A green roof can be a wonderful architectural element that helps to reduce building heat gain and the urban heat island effect while absorbing carbon dioxide, but it needs to be installed properly to avoid roof leaks, moisture damage, and expensive callbacks.
