Recycling is the reprocessing of old materials into new products, with the aims of preventing the waste of potentially useful materials, reducing the consumption of fresh raw materials, reducing energy usage, reducing air (from incineration) and water (from landfilling) pollution by reducing the need for "conventional" waste disposal, and lowering greenhouse gas emissions as compared to virgin production.
VOC stands for volatile organic compound – basically, any organic compound that evaporates readily into the atmosphere. Here, the term ‘organic’ isn’t a good thing - it means a compound that contains carbon. Typical sources of VOCs include paints, varnishes, moth balls, solvents, gasoline, newspaper, cleaning chemicals, vinyl floors, carpets, adhesives, sealing caulks, air fresheners, and pressed wood furniture. For you, exposure to VOCs can mean eye, nose, and throat irritation, headache, nausea, dizziness, asthma exacerbation, cancer, and liver, kidney, and central nervous system damage. Environmentally, these compounds contribute to global warming and can also damage soil and groundwater.
Post-consumer means any material that has been used by a consumer and then recycled for use in a new product. It is not the same as post-industrial waste, which is the reintroduction of manufacturing scraps into the manufacturing process.
Formaldehyde is known to have a number of negative health effects, including immune-system toxicity, respiratory irritation and cancer in humans. However, it still turns up in baby bath soap, nail polish, eyelash adhesive and hair dyes as a contaminant or break-down product.
