Recycling of water sachet

Wastes generally render our environment unfriendly and the worst of them all are those wastes that are non-biodegradable and as such, wastes of these forms (non-biodegradable) pose a serious threat to our environment.

One of these categories of non-biodegradable wastes is pure water sachets. They are found in virtually every part of Nigeria and various attempts have been made to biodegrade these pure water sachets. One of these attempts was carried out by
Nwachukwu al (2010) in their research paper titled “Occurrence and recalcitrance of polythene bag wastes in Nigeria soils” where they attempted to biodegrade pure water sachets by burying them in the soil and subjecting them to acid and alkaline treatments with strains of Pseudonomas Spp. All these attempts proved abortive as the pure water sachets could not undergo the process of biodegradation.

In view of this, it was suggested in this project to design a low cost pure water sachet recycling machine capable of recycling about 30 tons of pure water sachets per hour.

The recycling machine was designed and fabricated with a good material of construction and the heating chamber was Teflon coated in order to avoid the sticking of the melted pure water sachets while extruding the recycled pure water sachets in pelletized form.
