The developing anxiety towards prevention of ecological destruction and the unfilled requirement for more adaptable environmental friendly materials has prompted expanding interest about polymer composites, originating from sustainable sources and biodegradable plant materials, particularly from forests. The composites for the most part are referred to as ‘green’ and can be used in industrial applications. Green composites do not harm the environment much and could be satisfactory alternatives to petroleum-based polymers and polymer composites. Using renewable resources like vegetable oils, carbohydrates and proteins, to develop biopolymer matrices like in cellulose-reinforced green composites, it is possible to minimize the consumption of fossil oil resources. Vegetable oils are not costly, easily sourced and could be used to synthesize sustainable polymers. These have widened the utilization of plant fibres as reinforcements and have increased the possibility for sustainable and ‘biodegradable’ composites, which can be called ‘green’ composites as they satisfy the criteria of ‘green materials’. Thus, the challenge to obtain ‘green’ composite involves obtaining ‘green’ polymers functioning as matrices in the production of composite materials. This chapter considers the materials and methods utilized for the fabrication and particularly the utilization of green composites in different technological fields. Furthermore, a discussion on the sustainability of major raw materials utilized in green composites is provided in this chapter.
