• Waste Water Treatment and Recycling Essay

  ...Solid and Hazardous Waste Treatment and Recycling ENV 497 Instructor April 21, 2014 Solid and Hazardous Waste Treatment and Recycling When it comes to sewage and solid waste in the community; I will use an operation called integrated waste management. This is a system that has several processes in its operation. “Source reduction, waste to energy combustion, recycling, materials recovery facilities, landfills, and composting all have roles to play in waste management (Wright, 2011,ch.21). Source reduction or waste prevention, is designing products to reduce the amount of waste that will later need to be thrown away and also to make the resulting waste less toxic. Recycling is the recovery of useful materials, such as paper, glass, plastic, and metals, from the trash to use to make new products, reducing the amount of virgin raw materials needed. Composting  involves collecting organic waste, such as food scraps and yard trimmings, and storing it under conditions designed to help it break down naturally. This resulting compost can then be used as a natural fertilizer (Municipal, 2014). I would also use transfer stations in the community. "Transfer stations are facilities where municipal solid waste is unloaded from collection vehicles and briefly held while...

• Impact of Leather Waste Essay

  ...1.1.1. Leather industrial waste: Prominent effectiveness of leather industry is amplified by high input and expenditure but on other side it causes huge waste of resource, incredible environmental pollution and biological chain destruction [17]. Streams of gaseous, liquid and solid waste are resulted by environmental blow of tanneries. Global leather industry generates 4 million tones of solid waste per year [18]. People use products of the leather-processing industry on a daily basis. These include especially shoes, leather and textile goods; we normally encounter leather products even in both public and private transport. The primary raw material for final products is hide from animals from slaughter houses and hide from game—i.e. waste from the meat industry, which is processed in tanneries and turned into leather. Therefore, the tanning industry can be considered one of the first industries to use and recycle secondary raw materials. Although the tanning industry is environmentally important as a principal user of meat industry waste, the industry is perceived as a consumer of resources and a producer of pollutants. Processing one metric ton of raw hide generates 200 kg of final leather product (containing 3 kg of chromium), 250 kg of non-tanned solid waste, 200 kg of tanned waste (containing 3 kg of chromium), and 50,000 kg of wastewater (containing 5...

• Essay on Waste Management with Lca

  ... In this issue: Waste Management & LCA : Study Material Waste Management & LCA Environmental protection is the buzz word today. It ranks very high in the public agenda of governments all over the world. Renewable energy and waste management sectors are getting a lot of attention from researchers and planners. But in this article we will focus on waste management sector. Waste is no more a garbage. It is now being considered as a resource. And recovery of resource is one of the prime objectives of present day Waste Management systems. It is worth noting here that there is no single technology that is capable of taking care of various wastes like plastics, glass, metals, bio-waste etc. Wastes contribute a lot in overall environmental burden and take up a lot of space as land fill sites. Also the nature of wastes is getting more complex day by day. It has, therefore, become imperative to have sound waste management strategies and policies for optimised environmental protection. LCA is increasingly utilised for solid waste management systems especially in the decision-making process and in strategy-planning. LCA has been utilised for sustainable MSW management since 1995. LCA is an ideal tool for application in MSW management because geographic locations, characteristics of waste, energy...

• Waste and Energy Essay

  ...Waste and Energy Paper ENV / 100 October 28, 2013 Pamela Primrose Waste and Energy Paper Environmental Science is a way to obtain agricultural knowledge of how things are going on around the world and the effect it has on the environment. In this document you will obtain a brief explanation of nuclear waste, plastic, coal and oil. What are the alternatives of other energy resources, advantages and disadvantages that would contribute to stabilize the environment currently around the the surrounding areas. Effects: Plastic is one of the most used resources that society has; the most common are plastic bags and beverage bottles. Plastic though durable is very slow to degrade. Plastic is sourced from two major categories, thermoset and thermoplastics; thermoset means that the plastic solidifies when it’s heated. Thermoset plastics are most commonly used in cars and construction; soften when heated however they resume their original composition when at room temperature. Some common thermoplastic products include milk jugs, credit cards and carpet fibers. Plastic makes up 13% of solid waste in our water system ; shockingly 8% of plastic is recycled. Plastic in our soil can block the flow of water through the soil as well as hinder the growth production. Plastic covers about 40% of our world’s ocean surfaces. The greatest affect of all is the effect on our animals in the ocean; they are subject to death from...

• SUMMARY OF SOLID WASTE Research Paper

  ...Donna may Jusos Course/section: BSHRM 1-A Subject: ENSC 1 SOLID WASTE MANAGEMENT Solid waste is composed of a broad array of materials discarded by households, businesses, industries, and agriculture. Not all solid waste is actually solid. Some semi-solid, liquid, and gaseous wastes are included in the definition of solid waste. Defines solid waste to include garbage, refuse, sludge from municipal sewage treatment plants, ash from solid waste incinerators, mining waste, waste from construction and demolition, and some hazardous wastes. Since the definition is so broad, it is worth considering what the act excludes from regulations concerning solid waste: untreated sewage, industrial wastewater regulated by the Clean Water Act, irrigation return flows, nuclear materials and by-products, and hazardous wastes in large quantities. Facilities for the disposal of solid waste include municipal and industrial landfills, industrial surface impoundments, and incinerators. Incinerators that recover energy as a by-product of waste combustion are called resource recovery or waste-to-energy facilities. Sewage sludge and agricultural waste may be applied to land surfaces as fertilizers or soil conditioners. Other types of waste...
