  • Cleaner Production
    Chapter 1 Cleaner Production 1 CLEANER PRODUCTION 1.1 What is Cleaner Production?1 Over the years, industrialised nations have progressively taken different approaches to dealing with environmental degradation and pollution problems, by: · ignoring the problem; · diluting or dispersing the pollution so that its effects are less harmful or apparent; · controlling pollution using ‘end-of-pipe’ treatment; · preventing pollution and waste at the source through a ‘Cleaner Production’ approach. The gradual progression from ‘ignore’ through to ‘prevent’ has culminated in the realisation that it is possible to achieve economic savings for industry as well as an improved environment for society. This, essentially, is the goal of Cleaner Production. Definition of Cleaner Cleaner Production is defined as the continuous application of an Production integrated preventive environmental strategy applied to processes, products and services to increase overall efficiency and reduce risks to humans and the environment. · For production processes, Cleaner Production involves the conservation of raw materials and energy, the elimination of toxic raw materials, and the reduction in the quantities and toxicity of wastes and emissions. · For product development and design, Cleaner Production involves the reduction of negative impacts throughout the life cycle of the product: from raw material extraction to ultimate disposal. · For service industries, Cleaner Production involves the incorporation of environmental considerations into the design and delivery of services. Difference between The key difference between pollution control and Cleaner Production is Cleaner Production and one of timing. Pollution control is an after-the-event, ‘react and treat’ pollution control approach, whereas Cleaner Production reflects a proactive, ‘anticipate and prevent’ philosophy.

The critical principles involve fund교 mental understanding of diverse industrial processes, adherence to the easiest techniques of a hierarchy for reducing wastes, and utilization of an underlying thought process to achieve pollution prevention successes that are both technically feasible and cost-effective. Chemical engineering has played a major and unique role in this environmental field. Improving the sustainability of cleaner production will rest on including this subject in the curriculum of university engineering. 1.

  • Process Management to Obtain a Cleaner Production in Discrete Manufacturing
    Process Management to Obtain a Cleaner Production in Discrete Manufacturing SANTOS, C. J. a*, BRANDAO, V. B.a , EMBIRUÇU, M. a, BARBOSA, A. S.a a. Universidade Federal da Bahia, Bahia *carlos.jeferson@gmail.com; Abstract In the national scene and the imminent presence of the water crisis in Brazil, it becomes mandatory to debate of environmental issues in the production environment as well as in its various sectors of activity. Human interference leads to a scarcity of natural resources caused, in most cases, poor management of these resources and the lack of proper management of waste generated in all processes. This article presents a case study of the implementation of a cleaner production methodology (CP) through the management processes of the existing workflows in a cleaning products company, aimed at implementing practical solutions to reduced consumption of water. These solutions, which include changes in the physical structure of the machines, alongside a joint work with the PPC and other areas involved, combining market strategies and productivity in order to reduce the setups of machines and use of water resources. Keywords: Sustainability, Cleaner, Water Resources Production. 1. Introduction Talk about environmental issues in the production environment becomes compulsory, in its different sectors of activity. The human interference direct a scarcity of natural resources scenario caused, in most cases, by poor management of these resources and the lack of proper management of waste generated in all processes. The applications of the resources found across the planet are linked to the past of humanity, in the archaic and manipulative way that society draw the necessary inputs for survival, as well as inputs for the very concentrated wealth in the minority of the people.

  • A Cleaner Production and Pollution Prevention in the Chemical Industries
    A Cleaner Production and Pollution Prevention In the Chemical Industries Prof. Dr. El-Sayed Khater Cleaner Production and Pollution Abatement Consultant National Research Center Department of Chem. Eng. And Pilot Plant Introduction . The terms Cleaner Production, Pollution Prevention and Responsible Care ® is often used interchangeably. In the case of Cleaner Production and Pollution Prevention, the distinction between the two tends to be geographic -- the term Pollution Prevention tends to be used in North America, while Cleaner Production is used in other parts of the world. The term Responsible Care® is a trade mark within the chemical industry and refers to a specific program -- the term is used universally. Background Information Cleaner Production stands for a proactive and preventive approach to industrial environmental management and aims for process- and/or product-integrated solutions that are both environmentally and economically efficient (‘eco-efficiency’). Pioneers in the field were large process industries in the USA (since the late 1970’s), but it took until the early 1990’s before Cleaner Production was generally recognised as a valuable approach for large and medium sized enterprises in all industry sectors. Cleaner Production/Pollution Prevention • Cleaner Production (CP) and Pollution Prevention (P2) focus on a strategy of continuously reducing pollution and environmental impact through source reduction -- that is eliminating waste within the process rather than at the end-of- pipe. Waste treatment does not fall under the definition of CP or P2 because it does not prevent the creation of waste. Cleaner production (CP) is a general term used to describe a preventative approach to industrial activity .It encompasses: .

Mary Crass was responsible for commissioning, editing and organising the contributions. Formword Ltd edited the case studies and prepared the page lay-out and diagrams. This document was produced by UNEP with the support of the Department of Trade and Industry of the United Kingdom. UNEP wishes to express its gratitude to all those who contributed to the preparation of this document. INTRODUCTION Companies around the globe are enjoying economic and environmental benefits from cleaner production. With this publication, a sequel to Cleaner Production Worldwide and Cleaner Production in the Asia Pacific Region, UNEP wishes to show the worldwide progress of cleaner production, and encourage its further development. Cleaner production Industries today must remain profitable in an increasingly competitive world, while accounting for the environmental impact of their activities. This challenge requires a solution that enables firms to maximize their economic gains, while taking the necessary steps to minimize the environmental degradation caused by their production processes and products. Cleaner production meets this dual objective. Cleaner production is a broad term that encompasses the concepts of waste minimization, waste avoidance, pollution prevention and other similar terms. It includes initiatives such as better management and housekeeping, substitutions for toxic and hazardous materials, process and product modifications and internal reuse of waste products.
