recycling bins

 RED containers for metal products and another thing red is associated with fire which is required to melt metals. GREEN is for paper products green is associated with trees and plants. BLUE is for plastics. Although the association is not as evident, blue is associated with water and plastic water bottles are currently one of the largest segments of plastics recyclables as well as a major water pollutant. YELLOW is for organics and glass products. Yellow is associated with the Sunshine that provides us the organic products. Glass is a silicate and by definition, may not be organic. But glass ground down into its most basic element is sand. Sand is a common compound in our organic environment. Large amounts of sand can be filtered out of organics. Smaller amounts of sand in organic mulch compounds help improve water aeration. Some individual areas may not yet be set up to process combined materials. Red may be used in some areas only for alluminum cans. Blue plastic containers in some areas may specify only water bottles. If it's the only plastic accepted (plastic is petroleum based hydrocarbons). Or an area may specify green for only paper products (not cardboards). Yellow can be used for organics, where organic recycling is prevalent. Or yellow can be used strictly for glass bottles, where glass recycling is available. By standardizing colour codes for recyclables .
