odour was tolerable to 19 th century sensitivities, walking through the streets without boots resulted in deplorable appearing footwear. In many cities, lacking trash collection, pigs and dogs ran loose, consuming the trash, but excreting dung, which smelled offensively. Dead animals, particularly horses, were left lying in the streets, facilitating disease. Ancient Solid Waste Disposal – Sustaining Our World The earliest laws we have concerning garbage dumps comes from Athens, Greece in about 500 BC. They mandated dumping trash at least a mile out of town and explicitly not in the streets. In 200 AD, Rome instituted the first documented sanitation force. It employed teams of two men to pick up trash from the street. They threw it into a wagon, and took it away. ‘Away’ in this case may have been a dump. Or perhaps they simply emptied the wagon into the Tiber somewhere downstream. Similar practices continued in medieval Europe. History records numerous laws of either a kingdom or city to deal with household waste management. As early as 1297, English towns attempted to require householders to clear the refuse from the front of the house. As cities grew, they, like ancient Rome, designated people to be responsible for collecting waste and taking it out of town. Collecting waste included raking excrement out of streets and alleys. The French failed to follow Athens’ wisdom in keeping the dump far from the gates. During the Hundred Years War, enemy soldiers could climb the massive garbage piles to storm the walls. Difficulty in Electronics Recycling - eToxics One can spend all day figuring out where to take e-waste, and once a recycling centre is found, there is no guarantee that it will be safely recycled. Up to 80% of the US e-waste is exported to developing countries where toxic components are burned, dumped or smashed apart by impoverished workers and children without proper protection. ‟ Extended Producer Responsibility is a solution that pushes companies to eliminate toxins from their products and production facilities, take their products back after consumers are done with them and reuse the materials from their recycling. Or they are sent to the US prisons where inmates work without federally protected health, safety or labour rights. Only 10% of unwanted and obsolete computers are recycled responsibly. Since electronics are made with nearly 1,000 chemicals and designed in such a way that they are difficult to take apart, they are nearly impossible to recycle them. Policies have come out banning most electronic products from landfills. Some have put a consumer tax on electronic products for the cost of their disposal while others require electronic companies to pay for recycling. Washington and Maine have recently passed the most extensive e-waste bills in the country. Extended Producer Responsibility (EPR) is a policy that is being used in parts of the world such as Japan and Europe. It includes electronics and many other products, including cars! EPR requires electronics companies to take responsibility for the effects of their products, from the materials used to the production, and to their disposal. EPR is a solution that pushes companies to eliminate toxins from their products and production facilities, take their products back after consumers are done with them and reuse the materials from their recycling. This protects workers and the environment through the entire life span of an electronics product. Some companies have already committed to an EPR approach and offer to take back your computers and other electronics items. 79
