Abstract

Around the world, growing energy consumption from rapid urbanization and industrialization together with the overwhelming reliance on fossil fuels is affecting the integrity of both natural and human systems. Additionally, rising oil and gas prices and potential future shortages lead to concerns about the security of the energy supply needed to sustain our economic growth. This has resulted in an increased awareness for environmental sustainability in all industrial sectors. In the agricultural sector, sugar crops processing for the production of sugar generates a wide variety of by-products. Their reuse represents a prime opportunity for value capture and for the sugar processing industry to be in the forefront of sustainability, while possibly realizing additional profits. Sugar crops such as sugarcane and sugar beets are versatile in that they include a rich sugar fraction (sucrose, syrups) in addition to fiber (cellulose), fodder (green and brown leaves and tops), fuel and chemicals (bagasse, molasses), and fertilizer (press mud). This is the first of two papers where production of several by-products is detailed together with their specific physicochemical properties and the ways in which they can be utilized beneficially and sustainably. In the second paper, state of the art value-added conversion technologies for these by-products are described in detail.
