试卷: LEED GA模拟题B[查看] What statement is true regarding wool carpet made from wool leftover from the carpet manufacturing process? A: This material is an example of pre-consumer recycled content B: This material is an example of post-consumer recycled content C: This material does not contain recycled content D: This material is an example of post-industrial recycled content 参考答案: C
本题解释: Pre-consumer content - formerly known as post-industrial content, is the percentage of material in a product that is recycled from manufacturing waste. Examples include planer shavings, plytrim, sawdust, chips, bagasse, sunflower seed hulls, walnut shells, culls, trimmed materials, print overruns, overissue publications, and obsolete inventories. Excluded are materials such as rework, regrind, or scrap generated in a process and capable of being reclaimed within the same process that generated it (ISO 14021);
Post-consumer material - recycled material generated from the waste of household, commercial, industrial, or institutional end-users
Postconsumer recycled content - is the percentage of material in a product that was consumer waste. The recycled material was generated by household, commercial, industrial, or institutional end-users and can no longer be used for its intended purpose. It includes returns of materials from the distribution chain. Examples include construction and demolition debris, materials collected through recycling programs, discarded products (e.g., furniture, cabinetry, decking), and landscaping waste (e.g., leaves, grass clippings, tree trimmings). (ISO 14021);
C item example would not be considered any type of recycled material. If a manufacturing process uses scraps and puts them back in the assembly line, it is a good practice but it does not count towards pre or post consumer recycled content;
Post-industrial content is now called pre-consumer content.Reference: LEED for Existing Buildings: Operations & Maintenance Reference Guide, Glossary |
