Non-Hazardous Landfill

*confined to as small area as possible
*compacted to reduce their volume
*covered (evenly daily) with layers of soil

Products Not Acceptable in the Landfill
by City of Colombia, Missouri

1. Hazardous waste (from sources other than HH)
2. Households (HH) hazardous waste
3. Infectious waste which had not been rendered innocuous
4. Lead-acid batteries
5. Tires which had not been cut, chipped or shredded in accordance with local laws.
6. Major appliances

Steps on how Waste Collectoion Vehicles bring the waste to the Landfill:

1. Weighbridge weigh the waste collection vehicles on arrival and their load is inspected for wastes that do not accord with the Landfill waste acceptance area.

2. Waste collection vehicles go to tipping face or working front to unload their contents.

3. Compactors or Bulldozers are used to spread and compact the waste on the working face.

4. The Waste Collection vehicles then passes the wheel cleaning facility. If necessary they return to the weighbridge to be weighed without their load.

5. Through the weighing process, the daily incoming waste tonnage can be calculated and encoded in database for record keeping.

6. In the working face, the compacted waste is covered with soil or alternative materials such as chipped woods and other green waste, etc. and covered with temporary blankets. Blankets can be lifted into place at night and removed the following day prior to waste placement.

7. Daily Cell – is the space that is occupied daily by compacted waste and is covered by waste cover materials.

8. Waste compaction is critical to extending the life of a Landfill. The more compacted the waste, the more waste can be placed in the Landfill.

Operations of the Landfill are governed by the laws of the locality and/or the State.

Uses of the Landfill Site after it is closed:

1. Parks
2. Sports Grounds
3. Cemeteries
4. Botanical Garden
5. Others

Comments:

Several cities in the Philippines have built their own Landfill Sites with Feasibility Studies prepared with support from foreign government’s aid agencies like AusAID with funding assistance from local banking institutions, the World Bank or locally financed by the LGU themselves. These cities are Tagaytay, Puerto Princesa, among others.

Bacolod City was assisted by PRMDP-AusAID in the preparation of their Landfill Feasibility Study and the training of their personnel from the Engineering, Environment and other departments.
