Sugar mills produce wastewater, emissions and solid waste that impact the environment. The massive quantities of plant matter and sludge washed from mills decompose in freshwater bodies, absorbing all the available oxygen and leading to massive fish kills. In addition, mills release flue gases, soot, ash, ammonia and other substances during ...

48 Lignin is a constituent of woody plants that functions as a strengthening element. Lignin sulfonate is a 49 derivative of lignin, where the lignin has been sulfonated in a wood pulping process (Zhor and Bremner, 50 1999). Lignin sulfonate has the chemical formula C 20 H 26 O 10 S 2 (NLM, 2013b) and its structure is presented 51 in Figure 1.

Feed mills receive incoming ingredients by both rail and truck (including hopper-bottom, bulk-solids and liquids trailers). Rail receiving hoppers should be designed to provide maximum capacity, but are usually relatively shallow, which constrains carrying volume. Rail and truck hoppers between 1000 and 1200 bu in capacity are common.

Wind is an emissions-free source of energy. Wind is a renewable energy source. Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. Wind turbines do not release emissions that can pollute the air or water (with rare exceptions), and they do not require water for cooling.

Factories and sewage treatment plants are two common types of point sources. Factories, including oil refineries, pulp and paper mills, and chemical, electronics and automobile manufacturers, typically discharge one or more pollutants in their discharged waters (called effluents). Some factories discharge their effluents directly into a waterbody.
