Here are a few common terms from the every expanding green vocabulary that you may run into when choosing eco-friendly products.
Biodegradable - Products manufactured from materials that are able to decompose safely in the environment. Most organic waste, including paper and natural fibers, fit this description.
Composting - Recycling organic household waste and yard trimmings creates a soil end-product called compost. The key benefits of composting are that it reduces the amount of green waste going into landfills and creates excellent planting mulch.
Carbon Footprint - A measure of the amount of carbon dioxide an individual or household produces through car emissions, electricity use, and fuel consumption. The bigger the footprint, the greater the contribution to global warming.
Energy-Saving - These products reduce or eliminate battery or electrical use in favor of alternative resources such as dynamo power, solar energy and water energy. Choices range from clocks, lights and calculators to radios and emergency cell-phone chargers.
Organic - Plants or foodstuffs grown or raised without the use of synthetic pesticides, fertilizers, antibiotics, or growth hormones. Products that can be produced organically include foods, fabrics, and gardening supplies, all of which must meet government requirements in order to be labeled organic.
Recycle - This is the process of taking materials that would be thrown away, most likely ending up in landfills, and instead, reusing them. Recyclable materials are typically broken down into their raw components and then made into new products. Recycling reduces landfill growth and the pollution caused by manufacturing new products.
Recycled - Products made from recycled plastic and paper, these items keep trees from being cut down and save additional energy that typically goes into harvesting non-recycled materials. Recycled materials fall into one of two 
categories:
Post-Consumer - Something that is used and discarded by a consumer. Purchasing recycled products made with post-consumer material is generally considered better for the environment as it is directly diverted from the waste stream and buying it supports local recycling programs.
Post–Industrial - Also known as pre-consumer waste, it is the leftover material following the manufacturing process.
Renewable - A natural resource that is depleted at a slower rate than the rate at which it regenerates. A resource must have a way of regenerating itself in order to qualify as renewable.
Re-Use - Products designed to be used for an extended period of time. Products that replace throwaway items - lunch sacks, grocery totes, and beverage containers - are great suggestions for clients who haven’t totally warmed up to green is reusable
Sustainability - To use a resource without depleting or permanently damaging it, allowing it to meet the needs of the present without compromising the needs of future generations. These resources are naturally replenished at the same rate that they are consumed and include products made from organic cotton, cotton canvas, bamboo and corn.
