- Algae toxicity
Several Genera and Species of Green Algae found in lakes, ponds, and streams that are responsible for aquatic oxygen balance and food sources for fish are tested for their reaction to chemical exposure. Chemicals that kill algae are considered dangerous to aquatic eco-systems due to the possible food chain effects and food source depletion. Algae Toxicity is a measure of a substance’s toxicity when consumed by these various types of Algae. A common measuring tool is EC50 (“effective concentration”), which is the concentration of a substance in the water required to stop photosynthesis of fifty (50) percent of the algae test population. If EC50 < 10 mg/L, the substance is considered algae toxic.

- Readily disassembled
Capable of being deconstructed with the use of common hand tools (i.e. wrench, screw driver, pliers, scissors, etc.).
A material can technically be recycled at least once after its initial use phase. At a minimum, the material’s physical and mechanical properties allow it to be re-melted or size reduced and used as filler with similar or dissimilar materials (downcycled). It is preferable to select materials that may be recycled into like or higher value products when possible. However it is understood that this is difficult to define as the collection infrastructure and recycling technologies are still in the early stages of development and the economic value of materials will change in the future.
Unless there is an automated process for disassembling and reducing size of materials with adequate identification and sorting technologies to produce the highest quality recyclate possible, then attention must be paid to the design and construction of products so that dissimilar materials can be economically separated for recycling. Ideally, disassembly instructions are provided to the end user and/or recycling facilities, recyclable parts are marked, and disassembly is possible using commonly available tools. If the product is too complex for the consumer or third parties to disassemble and/or is designed as a Managed Nutrient, the consumer should be provided with instructions on where to send the product after use.
The Cradle to Cradle definition of “recyclable” is different from the U.S. Federal Trade Commission (FTC) definition. While the intentions of the FTC to protect consumers from deceptive marketing claims is logical and laudable, it may also be unintentionally creating disincentives for manufacturers because it limits their ability to use the diversity of materials whose physical properties are very recyclable, but that are not actually recycled, due to the lack of economically profitable collection and recycling systems.
- Recycled content
Proportion, by mass, of recycled material within a product that has been recovered or diverted from the solid waste stream, either during the manufacturing process (pre-consumer/post-industrial) or after consumer use (post-consumer).
- Renewable energy credit
