Keratin-Based Non-Woven Screening for Green Houses in Africa

<p>Insects are known vectors of both human and plant pathogens. In addition, manure particulates may be transported to fresh produce. Effective temporary barriers are required to protect food products during growth and transport, particularly when in close proximity to raw maure. The goal of this project is to utilize poultry feathers (a common waste product in Africa) to produce an inexpensive non-woven screening that can be used to cover green houses. Non-woven keratin fabrics can be made by heating mixtures of feather fiber with small amounts of synthetic fiber in commercial dryers to create a 3-D array which, depending upon processing parameters, may have different densities and porosities. This keratin non-woven fabric barrier is porous and water resistant. The fabrication of non-woven fabric from keratin is already an existing technology. This project will focus on developing the required processes for application as green house screening. If successful, the Gates Foundation may provide $1, 000,000 for commercialization.</p>
