Traditionally considered a coarse fibre, kenaf is finding its place in the automotive and electronics market thanks to its use as reinforcement in composites. Its combination with PLA, a bioplastic sourced from corn, may illustrate the new focus of materials’ development nowadays. 2009 has been declared by the FAO the International Year of Natural Fibres. This is post is the third in a series dedicated to natural fibres.
What is Kenaf?
Kenaf, or Hibiscus Cannabinus, belongs to the Malvacean family and producers are based around the globe, although India and China are the major producers. Often compared with jute and hemp, kenaf applications could be classified as it follows:
traditional uses, low value: rope, twine, clothing, animal bedding and feed
Innovative Applications, medium value: Paper, engineered wood, environmental mat, oil and liquid absorbent material
Kenaf Oil: edible oil, can also be used in cosmetics, lubricants and production of biofuel
Composite materials, high value:...

WEEE and RoHS: How they affected plastics in electronics?
Introduction
Today I will discuss how the electronics market is changing its approach to sustainability, forced mainly by legislation. When talking about electronics, many products are included: mobiles, computers, DVD and CD players, etc.
A 2007 report of the UN University estimated that the amount of new electrical and electronic equipment, EEE, put in 2005 in the EU27 market was 10.3 million tonnes. The waste generated by electronic and electrical equipment, WEEE, in 2005 was lower, between 8.3 and 9.1 million tonnes. The same report also forecasts that in 2020, WEEE will reach 12.3 million tonnes.
The volume of electronic waste generated by Europe and the concerns raised by how this waste is treated have lead, among other factors, to three European directives: WEEE, RoHS and REACH. By concerns about how WEEE is treated in developing countries, see the links under Others, at the bottom of the post.
