Scrap Tyre & Rubber Recycling issues in South Africa
| New
project to collect waste (scrap)
tyres in SA
The SATRP Company (South African Tyre Recycling Process Company) has been created and an elected board of directors is working actively, to establish a sustainable system, for the collection of all waste tyres from dealers and to provide them to recyclers and other the end-users. Collections are expected to begin in 2006. The project will encourage growth in the recycling industry with associated job creation. Exports of recycled rubber products will also be possible. The project will contribute to the improvement of: Health. A reduction of mosquitoes, other insects and rodents due to the elimination of their breeding grounds in tyre stockpiles,
Pollution. A reduction of air pollution caused by the smoke that is generated from waste tyres burnt in order to recover their steel content that is then sold to scrap dealer,
Road Safety. A reduction of road accidents due to fewer waste tyres being sold as second hand tyres to unsuspecting vehicle owners. |

| Legislation A Waste Tyre Regulation through the Department of Environmental Affairs & Tourism is planned to be promulgated by February 2005.
Objective of Regulation The primary objective is to establish a Regulation to control the collection and disposal of waste tyres in South Africa through a network of registered waste tyre collection agents and accredited waste tyre users. Other objectives are to encourage the establishment of a sustainable, environmentally sound, waste tyre user industry, promoting component recycling and energy recovery, with a view to attaining the goal of zero waste tyre disposal to landfill and for positive job and wealth creation. |

of the Products made out of waste tyres * Crumb Rubber Asphalt in roads. Lengthens surface life and gives a smoother ride as well as dampening road noise * Low-income housing using waste tyres as the main structural material * Rumber Materials Inc. Austin Texas, combined waste tyres with polyethylene or polypropylene, for use by original Equipment manufacturers to make their polymer products stronger, more elastic and longer-lasting. * In Washington - park benches, carpet backing, Railroad crossings are frequently made with recycled rubber. * Rubberised synthetic turf for tee boxes at golf courses and driving ranges. * Running tracks, gymnasiums, fitness facilities, skating and hockey rinks, indoor and outdoor athletic fields, children's playgrounds, polo and equestrian fields. * Eco-Blocks is a patented process of Lakeland. Tyres are crushed into bales, bound with carbon steel banding, then encapsulated with concrete to form blocks weighing 10,000 pounds (±4545kg) and containing approximately 140 tyres, which could be used as sound barriers, retaining walls, breakwaters and river channels.

Basel Convention Technical guidelines on the identification and management of used tyres Annex 5 Recycling Technologies and Energy recovery End-of-life tyres can be used for environmentally safe applications in whole, cut or stamped form. * in civil engineering works; e.g. highway crash barriers, sound absorbing walls, boat fenders on harbour walls; * as coastal protection and off coast break waters; * as insulation * to consolidate steep slopes on roadway sides; * as artificial reefs to provide shelter or breeding grounds for sea life; * as cover material in agricultural application and for landfills; * as material to be cut up into mats, floor tiles, dock fenders, muffler hangers, support pads for back hoes, as clothing accessories such as belts, handbags, shoe soles and buttons; * as temporary roads for moving heavy construction equipment; in irrigation systems as reservoirs or channel water
Some of the many products which can be manufactured from different sizes of rubber granulates:- * compound material in rubber industry for various applications; * flooring and surface for indoor and outdoor sports; * solid tyres; * roofing material; * carpet underlay; * underlay for artificial sports turf; * thermoplastic and rubber blends; * road surfaces (modification of bitumen with rubber); * component in friction material; * Sami's road joints, and roadway filter drains; * porous drainage pipes; * children's playgrounds, tennis courts, soccer pitches, etc.; * train and tram line beds and track guards; * road furniture including crash barriers, speed bumps, among others; * outdoor sports and camping equipment; * as a composting material for heavily trafficked areas; etc.
Quantity used depends upon the producers formula and job specifications. Basel Convention Technical guidelines on the identification and management of used tyres - www.basel.int |
