This is what is left over. The un-recyclable material which consists of dust, cigarette ash, the vacuum cleaner bag, toothpaste tubes, takeaway packaging, leftovers, sanitary products, garden hose, crisp packets, broken toys, etc. This is the only waste that need be in your bin.
The concept and origin of the three arrows of recycling can be traced back to April 1970when the first Earth Day was observed and a contest was held.Gary Dean Anderson, a graduate student at the University of Southern California in Los Angeles took first prize . The winning entry was to be used to identify products and packages made from recycled and recyclable fibers.
This symbol and variations of recycling is used to designate recyclable materials. It is composed of three chasing arrowsthat form a continuous loop. This symbol is not a trademark. It is in the public domain and can therefore be used by anybody.
