These systems include residential curb-side or household collection of co-mingled or segregated recyclables and separate containers for high volume commercial generators.
While the situation may vary from City to City worldwide, the advantages of a co-mingled or “Blue Bag System” for residential MSW are highlighted below –
- The Blue Bag system enjoys the highest participation rate of any type of recycling program (~ 75 % or greater).
- Does not require new or specialized equipment.
- Collected on same routes as regular trash, so Blue Bags do not require separate collection routes.
- No increase in manpower for collection and transportation.
- Very low cost to implement – program can be implemented very quickly.
- Quality of recyclables improves because they are not in contact with regular trash.
- Quality of compost improves because impurities are removed from waste stream.
An example of potential revenues from recyclables from the Gulf Region is illustrated below –
- Ferrous Metals – $60 to $90 per ton.
- Cardboard – $60 to $100 per ton.
- Paper – $40 to $70 per ton
- HDPE – $100 to $300 per ton.
- PET – $100 to $350 per ton.
- LDPE – $0 – $30 per ton.
- Miscellaneous Plastic – $0 to $19 per ton.
- Wood – $5.5 to $11 per ton.
- Aluminum – $400 to $750.
- Miscellaneous Metals – $60 to $100 per ton.
- Glass – $0 to $33 per ton.
The above prices are subject to change and driven by market demand and are provided here to solely to illustrate the potential for recycling.
Perhaps more importantly – recyclables removed from the waste stream help to conserve valuable landfill disposal capacity – thereby increasing the available disposal capacity for a municipality, and in the long term reducing landfill operating costs.
