This will also reduce costs and ensure cash can be used elsewhere. 2. Avoid over-scheduling staff. One mistake many manufacturing business owners make is scheduling staff for shifts unnecessarily. Often managers will make a 'best guess' on staff numbers needed over a given period.
There are four main benefits of co-processing for climate action: 01. Reduction of CO₂ emissions in our manufacturing process. 02. Use of alternative fuels as a measure to help counteract pollution. 03. Decrease the amount of waste deposited in landfills. 04. Minimizing public investment costs for new waste facilities.
The cement production process. Cement production is energy intensive, requiring 3.3 Gigajoules of thermal energy per ton of clinker - so another source of carbon in the industry is the way plants are powered.

After cooling, the clinker can be stored in the clinker dome, silos, bins, or outside in storage piles. The material handling equipment used to transport clinker from the clinker coolers to storage and then to the finish mill is similar to that used to transport raw materials (e.g. belt conveyors, deep bucket conveyors, and bucket elevators).
