This paper is on the cost-benefit study on the use of mobile coffee hullers in remote areas of Papua New Guinea and their regulatory implications. Smallholder coffee growers have difficulty selling their coffee due to bad road conditions and high transportation costs. Furthermore, the coffee produced by smallholder growers is considered as “Y’ graded despite the good quality of their coffee. So this paper assesses the use of transportable coffee hullers in remote areas of PNG to help coffee growers reduce their cost and expenses. This paper contains five sections, (1) different types of mobile hullers available from different manufacturers, (2) analysis of possible costs and benefits of mobile hullers using different scenarios and possible costs, (3) the suitability and appropriateness of mobile hullers in PNG and finally and (4) discusses the regulatory implications by introducing mobile hullers in PNG.
