Electronic waste or e-waste in the United States refers to electronic products that have reached the end of their operable lives, and the United States is beginning to address its waste problems with regulations at a state and federal level. Used electronics are the quickest-growing source of waste and can have serious health impacts. [1]
Society today revolves around technology and by the constant need for the newest and most high-tech products we are contributing to a mass amount of e-waste. [20] Since the invention of the iPhone, cell phones have become the top source of e-waste products .

Electronic waste has been on the agenda of the Australian Federal Government since the mid-1990s. The Australian and New Zealand Environment and Conservation Council (now replaced by the Environment Protection and Heritage Council (EPHC)) was the first body to identify electrical and electronic waste as a concern.

Overview. Cellulosic ethanol is a type of biofuel produced from lignocellulose, a structural material that comprises much of the mass of plants and is composed mainly of cellulose, hemicellulose and lignin. Popular sources of lignocellulose include both agricultural waste products (e.g. corn stover or wood chips) and grasses like switchgrass ...
The long established method of waste treatment is simply landfill. Other technologies include composting and recycling. There are also a number of new and emerging waste treatment technologies which are able to treat a variety of waste streams. There is a move away from treating waste as a disposal problem towards recognising waste contains ...
Zero waste. Zero waste, or waste minimization, is a set of principles focused on waste prevention that encourages redesigning resource life cycles so that all products are repurposed (i.e. “up-cycled”) and/or reused. The goal of the movement is to avoid sending trash to landfills, incinerators, oceans, or any other part of the environment.
