For a recycling program to work, having a large, stable supply of recyclable material is crucial. Three legislative options have been used to create such a supply: mandatory recycling collection, container deposit legislation, and refuse bans. Mandatory collection laws set recycling targets for cities to aim for, usually in the form that a certain percentage of a material must be diverted from the city's waste stream by a target date. The city is then responsible for working to meet this target.
The amount of money actually saved through recycling depends on the efficiency of the recycling program used to do it. The Institute for Local Self-Reliance argues that the cost of recycling depends on various factors around a community that recycles, such as landfill fees and the amount of disposal that the community recycles. It states that communities start to save money when they treat recycling as a replacement for their traditional waste system rather than an add-on to it and by "redesigning their collection schedules and/or trucks."
The design objectives behind the bin were efficient use of space and safety: to provide at least as much space as the older round bins, whilst reducing the risk of injury caused by moving it. This is important for both the householder and the waste collector, who risked injury through lifting the traditional bin or from sharp, or possibly contaminated objects in garbage bags. Standardisation of dimensions is important because the bins must be lifted by a standard sized hoist on the dustcart. The bins are lifted by the lip at the front which must be designed for maximum stiffness and mechanical strength. The underside of the lip is therefore reinforced by numerous ribs in the case of the thermoplastic bins. Steel bins have a much simpler lip owing to the properties of steel.
Origins of recycpling
Recycling has been a common practice for most of human history, with recorded advocates as far back as Plato in 400 BC. During periods when resources were scarce, archaeological studies of ancient waste dumps show less household waste (such as ash, broken tools and pottery)—implying more waste was being recycled in the absence of new material.
Many recycling bins are designed to be easily recognizable, and are marked with slogans promoting recycling on a blue or green background. Others are intentionally unobtrusive. Bins are sometimes different colors so that user may differentiate between the types of materials to be placed in them. While there is no universal standard, the color blue is commonly used to indicate a bin is for recycling in public settings.
