Scrap is recycled in steel melting shop. Refractory waste depending on the condition either goes for mortar manufacture or is dumped. Lime calcining
mill waste or pre-chipped from debarked roundwood elsewhere, or as waste sawdust in the case of some pulping processes. If roundwood is used, it is first debarked, usually by tumbling in large steel drums where wash water may be applied. The debarked wood bolts are then chipped in a chipper if the pulping process calls for

Figure 9.10.1.1-1. The cane is received at the mill and prepared for extraction of the juice. At the mill, the cane is mechanically unloaded, placed in a large pile, and, prior to milling, the cane is cleaned. The milling process occurs in two steps: breaking the hard structure of the cane and grinding the cane. Breaking the cane
The major waste materials are rejects, different types of sludges and ashes when the paper mill has an on-site waste incineration system. Depending on the grades of raw material, process design, manufactured product and wastewater treatment, different amounts and qualities of wastes are generated.
This example details one typical waste life cycle at a textile mill. This life cycle presents the hazardous waste management requirements for an SQG from generation to shipment off site. Other waste life cycles could be differ-ent depending on the waste, whether onsite treatment will occur, the type of waste management units used, and the
Issues. Pulp and paper mills contribute to air, water and land pollution and discarded paper and paperboard make up roughly 26% of solid municipal waste in landfill sites.. Pulp and paper generates the third largest amount of industrial air, water, and land emissions in Canada and the sixth largest in the United States.

After spinning mill, there are wastes in yarn and fabric forms, and they need recycling to be put again in production. Postproduction wastes are generally worn out cloths, which can be recycled and may be used again in textiles or utilized in other products. Textiles include different raw material (fiber) types.
20 Lean manufacturing is a production methodology that focuses on reducing company process waste and, at the same time, boosts productivity. This manufacturing principle became widespread in the 1990s after a magazine featured the lean manufacturing processes used by the car manufacturer Toyota.

We also approved a global "Waste Management Performance Standard" that defines acceptable global waste-handling practices. We already beneficially reuse about half of our manufacturing residual waste.
The next process for waste pulp making is pre-flotation, which also aims to remove the impurities in the pulp. Then through heavy and slight slag remover, the purity of the pulp is further increased. The pulp will be sent into a thickener. The thickener will concentrate the pulp, increase the pulp concentration, and at the same time wash the pulp.
A kraft pulp mill can be divided into four main parts: (1) raw material handling; (2) pulping line with an almost closed chemical and energy recovery system; (3) bleaching with an open water system and (4) the external wastewater treatment system. Figure 5 shows the emissions sources to water from a kraft pulp mill.

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.
Whereas the solid waste composition from pulp and paper mills is known and constant, as a result of the current, highly controlled production processes, sludge compositions, on the other hand, vary widely throughout the industry and are dependent on the type of operations carried out at the mill.
