The First Rice Hull House
Rice Hulls in Construction. The rice hulls are unique within nature. They contain approximately 20% opaline silica in combination with a large amount of the phenyl propanoid structural polymer called lignin. This abundant agricultural waste has all of the properties one could ever expect of some of the best insulating materials. Recent ASTM testing conducted R&D Services of Cookville, Tennessee, reveals that rice hulls do not flame or smolder very easily, they are highly resistant to moisture penetration and fungal decomposition, they do not transfer heat very well, they do not smell or emit gases, and they are not corrosive with respect to aluminum, copper or steel. In their raw and unprocessed state, rice hulls constitute a Class A or Class I insulation material, and therefore, they can be used very economically to insulate the wall, floor and roof cavities of a super-insulated Rice Hull House. This paper also explains how the structure of such a house can be fashioned out of a variety of engineered lumber products derived from sugarcane rind.

Visit the Service learning Portal

Service learning as a teaching method combines community service with academic instruction that focuses on critical, reflective thinking and civic responsibility. Service learning programs involve students in organized community service that addresses local and global needs, while developing their academic skills, sense of civic responsibility, and commitment to the community. Internships offer ways individuals can learn from valuable work experiences while also contributing to the host's mission.

Service learning using Appropedia helps to create an essential knowledge base for the world via learning experiences for individuals and classes. The Appropedia Foundation and the Appropedia community work with universities via service learning courses, as well as service learning programs to create these opportunities. Appropedia internships also offer opportunities for service learning.
