  2. Waste minimisation - Wikipedia

    en.wikipedia.org/wiki/Waste_minimisation

    Waste exchanges represent another way of reducing waste disposal volumes for waste that cannot be eliminated. Ship to point of use This involves making deliveries of incoming raw materials or components direct to the point where they are assembled or used in the manufacturing process to minimise handling and the use of protective wrappings or ...

  3. Drain-waste-vent system - Wikipedia

    en.wikipedia.org/wiki/Drain-waste-vent_system

    In the U.S., every plumbing fixture must also be coupled to the system's vent piping. [1] Without a vent, negative pressure can slow the flow of water leaving the system, resulting in clogs, or cause siphonage to empty a trap. The high point of the vent system (the top of its "soil stack") must be open to the exterior at atmospheric pressure.

    Landfills waste are categorized by either being hazardous, non-hazardous or inert waste. In order for a landfill design to be considered it must abide by the following requirements: final landforms profile, site capacity, settlement, waste density, materials requirements and drainage.

  5. Mound system - Wikipedia

    The mound system was designed in the 1930s by the North Dakota College of Agriculture. [1] and was known as the Nodak Disposal System. In 1976, the University of Wisconsin studied the design of mound systems as part of the university's Waste Management Project. This project published the first ever design manual for identifying the appropriate ...

    Sewage treatment is the treatment and disposal of human waste. Sewage is produced by all human communities. Treatment in urbanized areas is typically handled by centralized treatment systems.

  7. Industrial wastewater treatment - Wikipedia

    en.wikipedia.org/wiki/Industrial_wastewater...

    Brine treatment systems are typically optimized to either reduce the volume of the final discharge for more economic disposal (as disposal costs are often based on volume) or maximize the recovery of fresh water or salts. Brine treatment systems may also be optimized to reduce electricity consumption, chemical usage, or physical footprint.

  8. Waste management - Wikipedia

    en.wikipedia.org/wiki/Waste_management

    Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. [1] This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms.

  9. Sewage sludge treatment - Wikipedia

    en.wikipedia.org/wiki/Sewage_sludge_treatment

    Thermal hydrolysis systems are operating at sewage treatment plants in Europe, China and North America, and can generate electricity as well as high quality sludge. [ 31 ] The use of a green approach, such as phytoremediation , has been recently proposed as a valuable tool to improve sewage sludge contaminated by trace elements and persistent ...
