It is among the priorities of developed and developing countries to produce economical and environmentally friendly composite materials. More efficient use of natural resources will be ensured by carrying out studies to minimize environmental pollution. A sustainable development is aimed as well as economic gain with the recycling of wastes. Waste motor oil, vegetable oil and newsprint fibers are also included in this scope. In this review, an ecological approach that will provide value to our country and increase our competitiveness in the domestic and foreign markets with environmentally quality products produced by using wastes in composites is presented. With this study, the obligation to acquire an environmentally friendly product that targets the solution of the problems related to wastes assessment will shed light on those interested in future environmentally sensitive research studies.
