National ENERGY GLOBE Award Viet Nam 2018

Styrobeton Composter

The private individual Wolfgang Koelblinger was concerned about the amount of polystyrene waste and became active in his neighborhood by implementing this small but effective project. Polystyrene which would else be deposited was processed into a mixture of polystyrene and concrete in order to build composters and raised beds. The neighbors of the settlement help to collect kitchen and garden waste so that they will be composted.

Initial situation
With increasing prosperity in Vietnam, polystyrene is not collected anymore but deposited together with the residual waste. Since many things like take-away food are packed in polystyrene, this material is widely available. A part of it ends in illegal landfills, rivers or in the sea. Due to its light weight it can easily be taken away by the wind and sometimes it is eaten by chickens. Another problem is the soil which is low in nutrients due to heavy rain falls. This called for building composters made from polystyrene!

Polystyrene was used in combination with concrete to build several composters for the neighborhood. Over time, the project was extended and the whole neighborhood started to bring their organic waste. Later on, these containers were also used to build raised beds. The advantage of compost is that the nutrients are bound and therefore available over a long period of time compared to mineral fertilizers. An idle piece of land was turned into a garden where the compost is used for the production of fruits and vegetables. In total, more than 3 tons of organic waste from 22 households have been composted. This project also creates awareness since the whole neighborhood became involved and can see the results with their eyes.

This project could easily be replicated in rural areas of Vietnam as the materials needed for building the composter are widely available and inexpensive. Since the used materials are so cheap, they are not likely to be stolen. The containers can easily be deconstructed for the use in other areas.
