Technology developed rapidly, science became advanced, and the manufacturing age came into view. With all of these came one more effect, industrial pollution.

What is Industrial Pollution?

You were introduced to the main types of liquid waste in Study Session 1. This study session is the first of three that builds on that introduction and describes liquid wastes in more detail. We begin with a closer look at the sources and characteristics of liquid wastes. Study Session 5 focuses on the different types of latrine available for urban areas in Ethiopia. In Study Session 6 you will learn about the management and treatment of liquid wastes. The type and composition of liquid waste depends on the source. In urban areas, the main sources are households, commercial establishments and industries.

We tend to look skywards when talking about pollution, but this problem is not confined to our skies. The soil in which our fruit and vegetables grow is also suffering its consequences, the effects of which getting to us directly, for instance, through the aforementioned foodstuffs. The time has come to look after what lies under our feet! Soil pollution is mostly caused by chemical substances produced by human activity. The soil is the skin of the earth, a mantle full of scars, thousand-year-old wrinkles and more recent injuries caused both by man and nature itself.

As illustrated in Figure , the typical waste-incineration facility includes the following operations:. Combustion in a furnace, producing hot gases and a bottom ash residue for disposal. Gas temperature reduction, frequently involving heat recovery via steam generation.

Tips for reducing industrial waste

Go back. Health impacts of solid waste. With increase in the global population and the rising demand for food and other essentials, there has been a rise in the amount of waste being generated daily by each household. This waste is ultimately thrown into municipal waste collection centres from where it is collected by the area municipalities to be further thrown into the landfills and dumps. However, either due to resource crunch or inefficient infrastructure, not all of this waste gets collected and transported to the final dumpsites.

Waste minimisation is a set of processes and practices intended to reduce the amount of waste produced. By reducing or eliminating the generation of harmful and persistent wastes, waste minimisation supports efforts to promote a more sustainable society. The most environmentally resourceful, economically efficient , and cost effective way to manage waste often is to not have to address the problem in the first place. Managers see waste minimisation as a primary focus for most waste management strategies. Proper waste treatment and disposal can require a significant amount of time and resources; therefore, the benefits of waste minimisation can be considerable if carried out in an effective, safe and sustainable manner.

What is Industrial Pollution?

Industrial waste is the waste produced by industrial activity which includes any material that is rendered useless during a manufacturing process such as that of factories , mills, and mining operations. Types of industrial waste include dirt and gravel, masonry and concrete, scrap metal, oil, solvents, chemicals, scrap lumber, even vegetable matter from restaurants. Industrial waste may be solid, semi-solid or liquid in form. It may be hazardous waste some types of which are toxic or non-hazardous waste.

When many of us think of pollution, images of smoggy cities and litter-infested oceans come to mind. While littering and gasoline-fueled cars are a major contributor to pollution, there are many other influences that are important to be aware of. Essentially, pollution occurs when substances are introduced to the environment that have harmful effects, damaging the quality of land, water, and air. The cause is the accumulation of solid and liquid waste materials that contaminate groundwater and soil. These waste materials are often referred to as municipal solid waste MSW , which includes both hazardous and non-hazardous waste. When waste is deposited onto an area of land, the permeability of the soil formations below the waste can increase or reduce the risk of land pollution. The higher the permeability of the soil, the more likely that land pollution will occur.

Solid-waste management , the collecting, treating, and disposing of solid material that is discarded because it has served its purpose or is no longer useful. Improper disposal of municipal solid waste can create unsanitary conditions, and these conditions in turn can lead to pollution of the environment and to outbreaks of vector-borne disease—that is, diseases spread by rodents and insects. The tasks of solid-waste management present complex technical challenges. They also pose a wide variety of administrative, economic, and social problems that must be managed and solved.

Jerry Spiegel and Lucien Y. Over the course of the twentieth century, growing recognition of the environmental and public health impacts associated with anthropogenic activities discussed in the chapter Environmental Health Hazards has prompted the development and application of methods and technologies to reduce the effects of pollution. In this context, governments have adopted regulatory and other policy measures discussed in the chapter Environmental Policy to minimize negative effects and ensure that environmental quality standards are achieved. The objective of this chapter is to provide an orientation to the methods that are applied to control and prevent environmental pollution. The basic principles followed for eliminating negative impacts on the quality of water, air or land will be introduced; the shifting emphasis from control to prevention will be considered; and the limitations of building solutions for individual environmental media will be examined. It is not enough, for example, to protect air by removing trace metals from a flue gas only to transfer these contaminants to land through improper solid waste management practices.

Solid waste management Methods. The Kasturirangan report by PC highlights the need for an integrated approach:. Classification of wastes based on types, i. Solid Waste Management; Types of Solid waste Management; Factors affecting Solid Waste Generation Solid Waste Management Solid waste management is basic public services which every citizen should have access to, both for health and hygiene, and for ensuring a good quality of living. Sanitation here refers to toilet facilities, whereas solid waste management refers to the management collection and disposal of solid waste as opposed to liquid waste.

Взбираясь по решетчатым ступенькам, Сьюзан смотрела на массивную дубовую дверь кабинета, украшенную эмблемой АНБ, на которой был изображен могучий орел, терзающий когтями старинную отмычку. За этой дверью находился один из самых великих людей, которых ей довелось знать. Пятидесятишестилетний коммандер Стратмор, заместитель оперативного директора АНБ, был для нее почти как отец. Именно он принимал ее на работу, именно он сделал АНБ для нее родным домом. Когда десять лет назад Сьюзан поступила в агентство, Стратмор возглавлял Отдел развития криптографии, являвшийся тренировочной площадкой для новых криптографов, криптографов мужского пола. Хотя Стратмор терпеть не мог выделять кого-нибудь из подчиненных, он с особым вниманием относился к своей единственной сотруднице. Когда его обвиняли в фаворитизме, он в ответ говорил чистую правду: Сьюзан Флетчер - один из самых способных новых сотрудников, которых он принял на работу.

    Reducing industrial waste can be a difficult task, with over a quarter of all waste generated in England coming from businesses, it is very important that businesses take steps in order to reduce the amount of industrial waste that they produce.
