To complete this series of definitions and to reduce the potential for any confusion that might occur later in this text, specialty chemicals (also called specialties or effect chemicals) are particular chemical products, which provide a wide variety of effects on which many other industry sectors rely. Specialty chemicals are materials used on the basis of their performance or function. Consequently, in addition to effect chemicals they are sometimes referred to as performance chemicals or formulation chemicals. The physical and chemical characteristics of the single molecules or the formulated mixtures of molecules and the composition of the mixtures influence the performance of the end product.

Thus, biomass, unlike natural gas or crude oil, offers a wide variety of compositions. In addition, the specific components of plants such as carbohydrates, vegetable oils, plant fiber, and complex organic molecules known as primary and secondary metabolites can be utilized to produce a range of valuable monomers, chemical intermediates, pharmaceuticals, and materials: (i) carbohydrates, (ii) vegetable oils, (iii) plant fibers, and (iv) specialty chemicals.

The textile industry is a large user of groundwater. In Bangladesh, this sector supplies itself with groundwater for the different units of wet processing facilities, and therefore is in desperate need of efficient water management. Almost all dyes, speciality chemicals and finishing chemicals are applied to textile substrates from water baths/using wet processes. In addition, most fabric preparation steps, including desizing, scouring, bleaching, and mercerising, use aqueous systems and groundwater (76).
