Environmental analysis of a village-level pressing machine for the densification of cans

Pangan, R.S.
The study focused on the environmental analysis of the developed pressing machine to determine the potential impacts of the introduced technology. An assessment of the need for a machine in the densification of cans was first conducted by gathering both primary and secondary data. As a result of these activities, the need for a pressing machine was established. Based from the gathered data, an appropriate machine was designed and fabricated which was very simple, affordable, made from locally available materials and can be easily fabricated by local artisans. Performance tests of the machine showed that the machine can press an average of 17.55 kilos of aluminum cans per hour and 27.37 kilos per hour of steel cans. Evaluating the machine in terms of its economic viability resulted to a positive incremental net benefit because of the considerable savings both in fuel and labor costs due to the reduced number of trips per month but having a much heavier load of materials. Using a 12 percent discount factor, the project's profitability was further substantiated because the benefit cost ratio (BCR) is 1.45 which is more than one, a positive net present value (NPV) of P22,846.20 and an internal rate of return (IRR) of 19.34 percent. The introduction of the developed machine resulted to a positive response by the majority of the surveyed junkshop owners towards the adoption of the machine. However, the machine should be modified to increase its capacity since they are paying their hired hands on a daily basis.
