This project is targeted to provide a solution for the waste tetra pack collection problem in a
new way of material development. There is a huge problem arisen with the collection of larger amounts of
Tetra packs in the country from the beverage and food packaging in Sri Lanka. But these do not have a
proper discarding method ora recycling method to avoid this problem. This Experimental project addresses
to provide material aspect solution for this waste type and finding out more possibilities of this waste
packaging material a new product after life. Project approach has been taken by studying about the current
scientific research done on waste material developments. Tetra pack waste has been tested mixing with
different ecofriendly substances, in different proportions. Each sample has been mechanically and
chemically tested to identify strongest material properties and with the ability to apply this ecofriendly,
biodegradable material to the natural context, potentials have been identified to get a product approach
matching to outdoor environment. With the parallel studies about the material and the problems in natural
environment, the problem of soil erosion has been identified as a situation where solution can be applied
from this strong material to strengthen weak soil structure. Material development has been stopped in a
stage where satisfactory material properties have been identified in the developed final sample with
correct proportions of mixed materials. The identified problem soil erosion has been thoroughly studied by
spotting Ratnapura, Malwala area as the sample context for the research. After doing a context analysis,
theoretical facts related to soil erosion, consequences of soil erosion, why soil erosion are identified.
Before approaching a product form, current landscaping solution given to reduce soil erosion are studied as
the precedence. Features, forms, textures, and other product qualities have been studied through this
precedence. Product with the ability to retain soil structure and to stay itself in the weak soil structure have
been the main targets of the product development. Geometric forms were developed and tested to select
most suitable form for the product with the main ability to retain in the soil, different cut shapes, number of
cuts, different protruded shapes, number of protruded parts have been applied in prototyping. Product has
been developed with an inner rough cavity to grow plant which can avoid soil erosion from the root system
growth. In this application, the product itself retains the weak soil layers in the first stages of its life span,
and while the plant growth happens, the structure begins to degrade and adds nutrients to infertile soil
found in frequently sliding soil structures. Production method is similar to brick molding and sun drying
method ls used to solidify the final unit in order to preserve organic additives in the tetra pack waste
mixture. Providing job opportunities, finding out different solution foe tetra waste and enhancing waste
material development field are the ultimate outcomes of this experimental research. |
