e-waste Electronic waste, "e-waste" or "Waste Electrical and Electronic Equipment" ("WEEE") is a waste type consisting of any broken or unwanted electrical or electronic appliance. It is a point of concern considering that many components of such equipment are considered toxic and are not biodegradable. http: //en. wikipedia. org/wiki/E-waste

e-waste It is estimated that e-waste contains over 1000 different substances. When these items are disposed of, they often leak toxic chemicals into the ground, air and water. Worldwide, as much as 4, 000 tons of e-waste are discarded every hour! In 2004, China discarded approximately 4 million refrigerators, 5 million TV sets and 5 million washing machines, and these figures are on the rise! China is receiving e-waste from other countries. It is estimated that between 50 and 80% of e-waste collected for recycling in the United States is shipped to Asia. China is the destination for around 90% of that material

WEEE directive Article 4 Product design Member States shall encourage the design and production of electrical and electronic equipment which take into account and facilitate dismantling and recovery, in particular the reuse and recycling of WEEE, their components and materials. Article 5 Separate collection 1. Member States shall adopt appropriate measures in order to minimize the disposal of WEEE as unsorted municipal waste and to achieve a high level of separate collection of WEEE.

The Restriction of Hazardous Substances Directive (Ro. HS) 2002/95/EC [1] was adopted in February 2003 by the European Union. The Ro. HS directive took effect on 1 July 2006, and is required to be enforced and become law in each member state. This directive restricts the use of six hazardous materials in the manufacture of various types of electronic and electrical equipment. It is closely linked with the Waste Electrical and Electronic Equipment Directive (WEEE) 2002/96/EC which sets collection, recycling and recovery targets for electrical goods and is part of a legislative initiative to solve the problem of huge amounts of toxic e-waste. In North America, it is often pronounced "ROHS", "Rosh", or "Row Haws". In Europe, it is pronounced "Rose".

Ro. HS Directive Each European Union member state will adopt its own enforcement and implementation policies using the directive as a guide. Therefore, there could be as many different versions of the law as there are states in the EU. Ro. HS is often referred to as the "lead-free" directive, but it restricts the use of the following 6 substances: Lead Mercury Cadmium Hexavalent chromium (Chromium VI or Cr 6+) Polybrominated biphenyls (PBB) PBDE (polybrominated diphenyl ether) PBB and PBDE are flame retardants used in some plastics. The maximum concentrations are 0. 1% or 1000 ppm (except for Cadmium which is limited to 0. 01% or 100 ppm) by weight of homogeneous material.

USA and e-waste As part of its implementation of the Electronic Waste Recycling Act, DTSC (Department of Toxic Substances Control) has tested certain types of electronic devices to determine which would be hazardous waste when discarded; only video display devices that DTSC "determines are presumed to be, when discarded, a hazardous waste" are potentially covered by the Act. Currently, these devices include: Cathode ray tube (CRT) devices (including televisions and computer monitors); LCD desktop monitors; laptop computers with LCD displays; LCD televisions; and plasma televisions. These devices are "covered" only if their viewable screen size is greater than four inches, measured diagonally. (Note: the electronic waste recycling fee will not be charged on LCD televisions or plasma televisions until July 1, 2005. )

California Ro. HS What Hazardous Substances will be restricted from use in electronic devices sold in California? The EWRA will restrict the use of: Lead, Mercury, Cadmium, and Hexavalent chromium

Humanity, Nature, and Technology: The Hannover Principles

Humanity, Nature, and Technology: The Hannover Principles The City of Hannover, Germany, was designated as the site of the world exposition in the year 2000. Hosting the world’s fair on the eve of the next millennium was both a great challenge and a great responsibility. By choosing “Humanity, Nature, and Technology” as theme for EXPO 2000, the city decided to directly address the difficult issue of imagining and encouraging a sustainable future.

THE HANNOVER PRINCIPLES 1. Insist on rights of humanity and nature to co-exist in a healthy, 2. 3. 4. 5. supportive, diverse and sustainable condition. Recognize interdependence. The elements of human design interact with and depend upon the natural world, with broad and diverse implications at every scale. Expand design considerations to recognizing even distant effects. Respect relationships between spirit and matter. Consider all aspects of human settlement including community, dwelling, industry and trade in terms of existing and evolving connections between spiritual and material consciousness. Accept responsibility for the consequences of design decisions upon human well-being, the viability of natural systems and their right to co -exist. Create safe objects of long-term value. Do not burden future generations with requirements for maintenance or vigilant administration of potential danger due to the careless creation of products, processes or standards. http: //www. mcdonough. com/principles. pdf

THE HANNOVER PRINCIPLES 6. 7. 8. 9. Eliminate the concept of waste. Evaluate and optimize the full lifecycle of products and processes, to approach the state of natural systems. in which there is no waste. Rely on natural energy flows. Human designs should, like the living world, derive their creative forces from perpetual solar income. Incorporate this energy efficiently and safely for responsible use. Understand the limitations of design. No human creation lasts forever and design does not solve all problems. Those who create and plan should practice humility in the face of nature. Treat nature as a model and mentor, not as an inconvenience to be evaded or controlled. Seek constant improvement by the sharing of knowledge. Encourage direct and open communication between colleagues, patrons, manufacturers and users to link long term sustainable considerations with ethical responsibility, and re-establish the integral relationship between natural processes and human activity.

Design for Sustainability. A new approach for Design: “Meeting the needs of the present without compromising the ability of future generations to meet their own needs. ”

Life Cycle Assessment (LCA) Specifically, LCA is a technique to assess the environmental aspects and potential impacts associated with a product, process, or service, by: Compiling an inventory of relevant energy and material inputs and environmental releases Evaluating the potential environmental impacts associated with identified inputs and releases Interpreting the results to help decision-makers make a more informed decision.

Life Cycle Inventory (LCI) A Life Cycle Inventory is a process of quantifying energy and raw material requirements, atmospheric emissions, waterborne emissions, solid wastes, and other releases for the entire life cycle of a product, process, or activity.

Life Cycle Impact Assessment (LCIA) The Life Cycle Impact Assessment (LCIA) phase of an LCA is the evaluation of potential human health and environmental impacts of the environmental resources and releases identified during the LCI. Impact assessment should address ecological and human health effects; it should also address resource depletion. A life cycle impact assessment attempts to establish a linkage between the product or process and its potential environmental impacts. For example, what are the impacts of 9, 000 tons of carbon dioxide or 5, 000 tons of methane emissions released into the atmosphere? Which is worse? What are their potential impacts on smog? On global warming?

Life Cycle Impact Assessment (LCIA) Two problems exist in impact assessment: There are not sufficient data to calculate the damage to ecosystems by an impact. There is no generally accepted way of assessing the value of the damage to ecosystems if this damage can be calculated.
