In 2004, Sony and Mitsubishi Plastics teamed up to develop a flame retardant PLA biodegradable resin claimed to be as strong as ABS. The new material will be used in the front panel of Sony standalone DVD players. The resin employs an aluminium hydroxide flame retardant, is rated UL94 V-2 and complies with the EU s Restrictions on Hazardous Substances (RoHS) directive. Sony says the use of additives and modifications to moulding parameters allows it to process PLA compound on conventional injection presses in commercially viable cycle times.

The Restriction on Hazardous Substances Directive and its mandate that new electrical and electronic equipment must be free of PBDEs by 2006 has in large part been a major catalyst for product redesign by electronic equipment producers. However, it can also be assumed that leading manufacturers had realized the feasibility of substitution. For instance, Hewlett-Packard monitor housings typically... 

Because polybrominated diphenyl ether FRs, along with heavy metals, are to be harmed from all new electrical appliances under the EU s Restriction on Hazardous Substances Directive (2002/95/EC), any recovered materials of these kinds must be directed to non-electrical...

The impact of lead-free manufacturing, as a result of the Waste Electrical and Electronic Equipment (WEEE) directive and Restriction on Hazardous Substances (RoHS), has changed surface finish specifications for PCBs and the soldering of those snrfaces at assembly. 

Perhaps the biggest impact will be over the use of solvents since many of the more common organic solvents are under threat from REACH these include N-methyl-2-pyrrolidone (NMP), dimethylformamide (DMF) and dime-thylacetamide (DMAc). (For more information on solvent substitution guides see Chapter 2, Tools for Facilitating more Sustainable Medicinal Chemistiy , by Helen Sneddon and James Sherwood s Chapter 3 on renewable solvent selection.) The electronics industry has also been subject to chemical legislation that aims to replace especially hazardous substances. RoHS (restriction on hazardous substances) targets certain chemicals, including lead, mercuiy, cadmium chromates and polybrominated flame retardants. ... 

WEEK (Waste Electrical and Electronic Equipment) and RoHS (Restrictions on Hazardous Substances) are linked— WEEE identifies the need for RoHS. WEEE is focused on the prevention, recovery, and safe disposal of waste. The WEEE Directive states The available evidence indicates that measures on the collection, treatment, recycling, and disposal of waste electrical and electronic equipment (WEEE) are necessary to reduce the waste management problems linked to heavy metals and flame retardants. Restricting the use of these hazardous substances is likely to enhance the possibilities and economic profitability of recycling. ... 

China, in addition to ratifying the Basel Convention, has a 2002 law banning hazardous waste imports. In 2005, the Management Measure for the Prevention of Pollution from Electronic Products became effective. It has been referred to as China s RoHS, specifying limits on materials similar to the EU Restriction of Hazardous Substances directive. A new waste disposal law enacted in 2009, Regulations for the Administration of the Recovery and Disposal of Electric and... 

Some companies are already using substitution as a means of eliminating hazardous chemicals from their businesses, (see Annex I) A variety of reasons exist for why some companies are searching for safer substitutes and these include regulatory drivers (such as the recent Directive on the Restriction of Hazardous Substances), increased public awareness, demands from downstream users or clients, worker protection, liability issues, competitive advantage and company ethics. However, there are also barriers and the development and adoption of safer substitutes is happening only slowly, in a piecemeal fashion and in some sectors not at all. 

The mandate within the Directive on the Restriction of Hazardous Substances (RoHS) to phase out a range of hazardous materials in new electrical and electronic products by 2006, has... 

In the case of green chemistry, and more especially chemical substitution, a number of policy instruments are relevant. The traditional approach is to ban certain toxic chemicals in order to induce substitution efforts. Such bans are usually preceded by examples of successful substitutions, as it is controversial to ban chemicals when no alternatives exist at reasonable cost. Otherwise, industry is often granted generous phase-in periods, in order to develop substitutes. A third way is to grant derogations when it is hard or very costly to develop substitutes. The latter approach has been applied in the context of the EU Restriction of Hazardous Substances (RoHS) Directive (Directive 2002/95/EC), which bans six substances in electrical and electronic products. A slightly less interventionist approach is to put restrictions on uses of certain chemicals. Other administrative approaches include the ban of chemicals, or restrictions in use, in individual operations when these apply for permits. 

Restrictions for lead are included in the EU Directive on Waste Electronic and Electrical Equipment [144] and EU Directive on Restriction of Hazardous Substances Directive [145], the EU End-of-Life-Vehicle [146] Directive. 

The European Union has taken the lead in restricting the use of some hazardous materials in the manufacture of electrical and electronic hardware. The program, referred to as Restriction of Hazardous Substances (RoHS), applies to all electrical and electronic products produced in Europe and products imported from other countries, thus has very broad application. The regulations put into force on July 1, 2006, apply to lead, cadmium, mercury, hexavalent chromium (Cr ), poly-brominated biphenyl (PBB), and polybrominated diphenyl ether (PBDE). The RoHS guideline document specifies 0.1% or 1,000 ppm as the maximum amount permitted for lead, mercury, Cr" " , PBB, and PBDE and 0.01% or 100 ppm for cadmium. The document also describes guidelines for sample preparation and analyses of the restricted materials. 

Restriction of Hazardous Substances (RoHS). RoHS regulations are focused on avoiding and reducing the use of heavy metals and other hazardous substances that could discourage or make complex the recovery of the product at EOU. 

The Restriction of Hazardous Substances Directive (RoHS) is the shortened form for Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment. It was adopted by the European Union in February 2003 [9]. In July 2006, the RoHS 1 directive took effect and was required to be enforced in each member state [10]. Each member state used the directive as a guide to establish its own enforcement and implementatiOTi policies. This directive restricts (with some exceptions) the use of certain hazardous materials in the manufacturing of various types of electronic and electrical equipment The hazardous materials include lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr polybrominated biphenyl (PBB), and polybrominated diphenyl ether (PBDE), [10]. 

Implementation of the Restriction of Hazardous Substances in Electrical and Electronic Equipment (RoHS) Directive 2011/65/EU Consultation, by the Department for Business Innovation Skills (2012). http //product-industries-research.hktdc.com/business-news/ article/Electronics-Electricals/BIS-Consultation-on-UK-Implementation-of-the-Recast-RoHS-Directive-2011-65-EU/psls/en/l/lX3VBFM5/lX07WHST.htm... 

Under the early draft, EU countries shall ensure that the use of lead, mercury, cadmium, hexavalent chromium, PBB, and PBDEs (polybrominated biphenyls and polybrominated diphenyl ethers) in electrical and electronic equipment is substituted on 1 January 2008. These have now become the subject of the Restriction of Hazardous Substances directive (RoHS). Additionally the Commission was proposing that all plastics containing BFRs be separated out from electrical and electronic equipment before recycling or disposal. 

RoHS Directive, The Restriction of Hazardous Substances in Electrical and Electronic Equipment, this Directive 2002/95/EC establishes standards and limits for the hazardous material content in electronic and electrical equipment. The Directive went into effect on February 13, 2003. It is scheduled to become European national law by August 13,2004 for be in force for products by July 1, 2006. Banned or restricted substances include lead, mercury, cadmium, hexavalent chromium, certain brominated flame retardants (PBBs), and polybrominated diphenyl ethers (PBDEs). 

Recently, Pb-free piezoelectric materials have been researched because of the toxin of Pb for health. It was applied as restriction of hazardous substances (RoHs) from 1 July 2006 based on directive 2001/95/EC of the Europjean Parliament and of the Coimcil of 27 January 2003,... 

RoHS Since the Directive on the restriction of the use of certain hazardous substances in electrical and electronic eqnipment (cotmnonly referred to as the Restriction of Hazardous Substances directive of the RoHS directive) came into force in the European Union (EU) in Jnly 2006 [167]. Some of the same regulations on chemical management have been adopted in other parts of the world. The RoHS directive restricts the amount of PBBs and PBDEs [168] contained in electrical and electronic equipment to less than 1000 ppm. No electronic electric apparatus can be marketed in an EU member state if it contains those materials in excess of a designated value of RoHS. PBBs and PBDEs are among the large variety of brominated flame retardants (BFRs) used in plastics and textiles. PBBs are no longer produced, but PBDEs were in widespread nse before the RoHS directive came into effect, and... 

With the implementation of the European Union (EU) directive on Restriction of Hazardous Substances (RoHS), the printed circuit industry has been forced to undergo a revolution in technology that is unprecedented in its history.The result is commonly called lead-free, a term that the reader will find used throughout this book, even though the restrictions are on several materials in addition to lead, as described in Chapter 1. The reason for this emphasis is that the biggest impact on the industry is the elimination of lead in the solder that is used for interconnection of the components and the board. 

A new requirement on packages— that of lead-free solder—has initiated a tremendous amount of developmental effort in the past few years. This effort stems from the requirement of packages exported to the European Union (EU) market, to pass Restriction of Hazardous Substances (RoHS) compliance requirements set forth in the Directive 2002/95/EC of the... 

In addition, the advent of the European Union s Restriction of Hazardous Substances (RoHS) directive and the lead-free assembly processes that result are redefining the requirements for base materials. RoHS has a severe impact on all aspects of base materials technology. The impact of lead-free assembly on base materials and a method of selecting materials for lead-free assembly are discussed in Chaps. 10 and 11. Requirements to support circuit densification, reliability, and electrical performance are also critical and will be discussed in Chap. 9. This chapter discusses grades and specifications of base materials, as well as the manufacturing processes used to make them.
