Effective Waste Management: Understanding Resources, Production, and Minimization Techniques

This document explores the concept of waste management, focusing on three essential factors of production: land, labor, and capital. It highlights various materials used as resources, including silk, lycra, sugar, wood, and metals, and their processing into products. It categorizes waste into inert, biodegradable, and hazardous types and discusses methods for waste management such as minimization, reuse, recycling, incineration, and composting. The benefits and disadvantages of effective waste management are also examined, alongside factors that influence it like stakeholders' needs, legislation, costs, and ethical considerations.

  1. Resources and waste Nathalie - Najat - Aurélie - Mathieu

  2. Brainstorming around the word « WASTE »

  3. 3 factors of production LAND LABOUR CAPITAL

  4. Process of production Resources Company Products Wastes

  5. The different materials = resources • SILK • caterpillars make fibres • make yarns • yarns are woven

  6. LYCRA • synthetic fibres • always combined with other materials • SUGAR • come from cane or beet • a sweetener to products • as by-products

  7. PINE • natural wool • ex : tables, chair, children’s toys … • MDF • = Medium Density Fireboard • produced by waste of wood • mixed with water, wax and resin

  8. METALS • natural materials found in roks : • iron, copper, tin • - join 2 metals  get the advantages of the originals metals • possible to change a metal

  9. WASTES = which is no longer useful 1996 : Special Waste Regulations  classifies differents types of waste

  10. Inert= materials which won’t cause environmental pollution • Biodegradable • = materials which rot away by the action of • living micro-organism • Hazardous • = materials which can damage health

  11. Exercise 1

  12. METHODS of dealing with waste WASTE MINIMISATION= avoid producing waste • RE-USE= re-use materials which would otherwise disposed of • RECYCLING = collect waste materials to produce a new raw material  bring system / collect system / central processing

  13. INCINERATION= burning materials

  14. LANDFILL= burying waste in the ground • COMPOSTING= collecting organic waste and allowing it to decompose  natural fertiliser

  15. DESIGN • Some methods : • JIT and kaisen • less packaging • development of concentrated product • - reducing product

  16. BENEFITS of waste management • reduce costs • lower prices to consumers • reduce tax • use waste to make products, which will be sold • improvment of the company’s image • avoid breaking the law and paying fines

  17. DISADVANTAGES of waste management • some aspects are expensive • higher prices to consumers • small business are disadvantaged

  18. Factors affecting waste management • NEEDS of STAKEHOLER possible conflit between shareholders and local communauty • LEGISLATION acts taken by the Government

  19. COSTS consider and compare the costs of the different methods • ETHICAL STANCE respect the laws and overcome the minimum legal standard • LOCAL INITIATIVES supports groups in some regions

  20. Fill in the blanksand you will have a good summary of the lesson Exercise 2
