  • Onsite treatment of wastewater and onsite dispersal of treated wastewater is not a new concept. Throughout the history of civilization in this country and other places in the world, onsite wastewater systems have been and will be an integral part of the overall wastewater management infrastructure. Onsite wastewater systems are here to stay and the U.S. Environmental Protection Agency (EPA) views adequately managed onsite systems as a cost-effective and long-term option for meeting public health and water quality goals, particularly in less densely populated areas....

  • This module will introduce you to several advanced topics concerning the operation and convergence of the Recycle unit operation. The HYSYS Recycle logical operation is used to solve looped systems where downstream material is mixed back in upstream in the process. The Recycle is a logical operation; it does not transform the stream that passes through it. The Recycle operation can be used several times in a given simulation. Every time a recycle operation is added, the total time needed for the simulation to successfully calculate and converge increases.

  • Depletion of mineral resources is one of the major problems in the world. We have consumed available resources as if they were unlimited, and at the same time we generate a huge quantity of waste, thereby contaminating the Earth. The amount of waste in our society reflects how much resources we consume. We, as modern society, create more products and packaging which is visually appealing but cannot be easily decomposed. Energy demands, resource limitations, and environmental pollution are closely linked.

  • Synthetic polymers are essential for modern human life, since they are used in industrial and agricultural fields. However, most synthetic polymers that have been developed by using petroleum and coal as raw materials are not compatible with the environment, since they cannot be included in the natural recycling system. There are serious contradictions between the convenience that people require today and compatibility with the natural environment. It is easy to say that we should use only natural materials in order to solve the problems coming from man-made materials.

  • Described as a structural/LID hybrid, the Modular Wetland System – Linear is a revolutionary stormwater treatment system. This treatment system utilizes an innovative combination of physically passive and natural biological treatment processes, including the use of a breakthrough filter media, BioMediaGREEN, which acts as a pre-treatment media filter for the enhanced 4th generation sub-surface flow wetland. These features combined with other various treatment and flow control technologies has lead to a system that maximizes pollutant removal and minimizes maintenance. ...

  • When delivering furniture, the packaging volume is considerable, as the pieces have to be delivered without being damaged. The reduction of the amount of packaging could be considered, however it would be difficult to evaluate this through a tender process without appropriate reference standards. Therefore criteria for packaging should concentrate on the recyclability, separability and the content of recycled material.

  • Many of the designations used by manufacturers and sellers to distinguish their products are claimed as trademarks. Where those designations appear in the book, and Manning Publications was aware of a trademark claim, the designations have been printed in initial caps or all caps. Recognizing the importance of preserving what has been written, it is Manning’s policy to have the books we publish printed on acid-free paper, and we exert our best efforts to that end.

  • This section illustrates that MBT systems can be described as two simple concepts: either to separate the waste and then treat; or to treat the waste and then separate. In some systems only biological treatment is required to treat all the residual MSW before disposal to landfill. Whilst a variety of treatment and mechanical separation options are offered, these need to be optimised in terms of the outputs in order to find outlets for the various materials / fuels derived from the process (see Markets for the Outputs section). ...

  • Sustainability in natural systems is built on the closed-end process of recycling materials. Our present society produces so much that is not recyclable, like resin-molded chairs and air polluting automobile tires, that it is necessary to apply intention to source reduction and product responsibility. Chapter 18 provides knowledge of municipal solid waste and how to disposal and recovery.

  • Once records have fulfilled their administrative, fiscal, or legal function they should be disposed of as soon as possible in accordance with their Records Retention Schedule. A properly completed schedule provides an agency with the legal authority to dispose of records entrusted to its care. Disposition may include sending appropriate records to an archival facility, recycling unneeded records, and/or destroying unneeded confidential records. Remember, in the event of litigation the court will want to know what the agency does in the normal course of doing business.

  • Earth's ecosystems continue to exist because they are sustainable. Two fundamental characteristics are crucial to sustainability. First, ecosystems' energy source, the Sun, is non-depletable and non-polluting. Second, there is efficient recycling of nutrients and other chemicals through organisms and through geological and chemical processes that result in no waste accumulation in ecosystems. This chapter provide knowledge of ecosystems: How they work.
