Organic Waste

  

Organic waste is waste originating from plant or animal sources and may be broken down by other living organisms. Such waste includes paper, food, green waste and garden waste.
 

This type of waste is commonly found in our Municipal Solid Waste which if disposed in landfills produces a gas which is composed primarily of methane, a greenhouse gas contributing to climate change. Whilst modern technology allows the recovery of much of this gas, alternatives to avoid the generation of this product are preferred. First begin with separating your food waste in the organic bin.  White bags are to be used for Organic Waste, which is collected every Monday, Wednesday and Friday from all localities in Malta and Gozo. You can find information regarding the home collection service here. Another alternative is to start with home composting.

 

Organic Waste Collection…the start of a new chapter in Malta’s waste collection

 

 

 

What happens to organic waste once collected?

All organic waste collected is sent to Sant’ Antnin Waste Treatment Plant where sorting systems are in place. This waste is turned into liquid form and placed into tanks without oxygen. A bacterial process will then take effect, generating gas. This process takes roughly 30 days to complete. At the end of the process, this product is then dewatered leaving us with material similar to compost. The compost-like material is derived from both the black bags and white bags. Hence there is a level of contamination and this material cannot as yet be used as a soil improver. Currently the SAWTP is being upgraded to be able to treat organic waste on its own which will eventually produce a less contaminated material.  In the interim until such works are concluded, organic waste is being delivered to and treated at the Malta North Facility.

 

 

How has Malta benefited?

The environmental benefits from a nationwide separation of organic waste for Malta are significant. The collected waste is used to produce energy, delivering clean electricity back to residents. During 2019 more than 27,000 tons of organic waste was collected, this exceeding by far the projections based on the pilot project.  However, this can potentially go up to 70,000 tons of organic waste with participation from all residents disposing of organic waste in the white bag rather than the black bag.

 

 

What waste can be placed in the white organic collection bags?

All cooked and raw food including bones, fish and shellfish, bread and pasta, rotten fruit and vegetables, fruit and vegetable peels, tea bags and ground coffee, egg shells, napkins and soiled papers, leaves and flowers can be disposed of in the white bag.

On the other hand, items such as cigarette stubs, nappies, food packaging, napkins used for sanitary purposes, foil, and branches should not be placed in the white bag.
