The economics of sugar mill waste management in the . Sugar mills produce a range of by-products during the process of sugar extraction. Mill mud is one of the by-products that is produced in significant volume. Often mill mud is mixed with mill ash from the firing of bagasse, which together forms the bulk of mill waste available for disposal ...
3.1 Chemical compositions of olive mill waste. Olive mill waste is characterized by low crude protein content (89 to 102 g kg −1 dry matter), reduced sugar (9 to 57 g kg −1 dry matter), and high fibre content (NDF>400 g kg −1 dry matter). The extracted olive cake caused the largest amount of lignocellulose waste.

Waste Disposal and Recycling in Steel Industry. Steel is a versatile commodity that plays a major part in everyday life—from food cans, containers, automobiles, and office buildings. Steel makes up the largest category of metals in the municipal solid waste (MSW) and industrial waste streams. Steel since ages has been a recycled ...
Log size greatly affects ratios of lumber and waste. Four logs 20" in diameter and 16' long will give over 1000 board feet of lumber with only 16 slabs. Ten logs 14" in diameter and 16' long will give 1000 board feet and 40 slabs. Sawdust amounts remain almost the same. The thickness of the lumber will change the amount of sawdust produced.
Wastes, which are produced from the hospitals, medical centres and nursing homes are called bio-medical wastes. These wastes are highly infectious which include used bandages, infected needles, animal remains, cultures, amputated body organs, dead human foetuses, wastes of surgery and other materials from biological research centres.

The steel industry generates the wastes red dust, mill scale, ... So this creates its own challenges in terms of management of solid waste produced from metal manufacturing industry.
Prod. 133 (2016) 953. estimate that waste production is most likely over one million metric tonnes per year. Currently, various inorganic and organic substances are generated in pulp and paper mills, such as ashes, green liquor dregs, slaker grits, lime mud and pulp mill sludge of waste water treatment plants (WWTP) 8 8.
In the early years of uranium mining after World War II, the mining companies often left sites without any clean up after the ore deposits were exhausted: often, in the United States, the mining and milling facilities were not even demolished, not to mention reclamation of the wastes produced; in Canada, uranium mill tailings were often simply dumped in one of the numerous …

Open pit uranium milling and in situ mining sites do not pose a significant radon risk to the public or to miners; the radon disperses into the atmosphere. In the past, the waste rock produced by underground and open pit mining was piled up outside the mine.
One of the first ways to minimize waste production from milling operations is to collect and recycle the metal chips/debris produced by the milling process. In most manufacturing centers, this is done via a third party. However, some companies have already begun using specialized equipment to recycle and reuse metal swarf internally.
The production rates of solid wastes and sludge in pulp and paper mills as well as their properties are significantly influenced by pulp manufacturing processes and wastewater treatment ...
Generally, wastes arising in the mills can be returned to the same blend from which they arose; comber wastes are mostly used in rotor spinning. In carded ring-spun yarn and fine rotor-spun yarn production, waste fibers can be used, up to 5%, but for combed yarns, waste fiber ratio can be lower, up to 2.5%.
In the mill the different type of the waste is remove from the different department that is product waste, process waste and invisible losses hence it is important that to manage the waste properly in the mill to increase the production and improving the quality of the material the waste which is reusable can be again fed in the blowroom mixing in order to form the yarn whilc hard …
