Glas, glas, stukke glas orals.

Gebreekte bottels (ex-misielle) in Hillbrow,
glas op ons strande, in ons parke en zoos (sommige parke is zoos),
glas in my (woongebied) straat (roekeloos uitgegooi vanaf 'n verbygaande
voertuig).

Hoekom het hierdie alkoholiese drank houers nie 'n terugkeer (deposito)
waarde nie? Daar moet 'n ekonomiese waarde wees vir gebruikte (herwinbare)
glas? Daar is suksesvolle besighede wat kuns en funksionele glas voorwerpe
skep van afval.

Hoekom nie die bottel fabriek (verskaffers/bemarkers) skuldig maak nie? Vir
die ekonomiese (opruiming vir toerisme), fisies (beserings) en omgewings
skade.

Wat van strenger toegansbeheer by publieke areas - GEEN glas houers! Daar is
'n wet teen die drink (van alkohol) in die publiek, maar niks word gedoen
oor die aksie/s daarna nie wat op wetelose vandalisme (breek van
glasbottels) ly nie.

Waar sal ons begin? Vergeet die opvoedingsaksie. Prosedeer die varke! OF hou
bottels heel, gee dit in vir 'n deposito vir hergebruik of herwinning.

People think of glass as one of the "true recyclables" along with newspapers
and aluminum and steel cans, but changes in the economics of recycling and
recycling collection systems have removed glass from that list in many
American communities.

Rather than let glass bottles return to the waste stream, some communities
are trying other means of glass recovery. While bottle-to-bottle recycling
may not be feasible in some areas, crushed bottle glass is being used in
asphalt, concrete, septic system filters, flooring material and other
engineering and building applications.

THE THREE Rs

Reduce, re-use and recycle. Recycle waste material into useable products.

Glass is 100 percent recyclable. Household bottles and jars are made from a
melted mixture of silica (sand), soda ash and limestone. Glass manufacturers
can use your old glass in this process.

glass recycling : an industry perspective

The recovery and recycling of used glass containers has always been of
critical importance to Consol Glass. Over the past years it has invested a
great deal of finance and staffing in ensuring that glass recycling moves
forward from strength to strength. As part of its social responsibility and
community development programmes Consol is committed to ensuring that
recycling of glass continues to benefit entrepreneurs throughout Southern
Africa. The reasons for this are both environmental and financial as
outlined below:

Conserves our irreplaceable natural resources

Although the ingredients of glass are plentiful they cannot be replaced.
Cullet allows the glass manufacturers to supplement these raw materials at
rates varying between 25 - 70 %. Glass is 100% recyclable.

Saves energy through lower melting temperatures

Reduction in energy costs as cullet melts at a lower temperature. The
factories therefore require less oil etc to melt the same quantities of
glass.

Conserves landfill space

Reduction in energy costs as cullet melts at a lower temperature. The
factories therefore require less oil etc to melt the same quantities of
glass.

Conserves landfill space

Glass is estimated at comprising 4.5% of the waste stream. Recycling this
valuable product allows for the better management of landfill sites, which
in turn will benefit the lifespan of the site.

Reduces litter

Entrepreneurs collect glass containers off the street which have been
improperly disposed of by the user.

Has educational value

Our children will grow up in the recycling way - caring for their
environment and fellow mankind.

Is linked to job creation and income generation

Unemployed persons are able to provide an informal income by way of
collecting and selling the glass to the processor. No capital outlay or
formal qualifications are necessary to collect this glass.

Generates funding for charities, schools, and welfare organisations

These organisations are remunerated for glass collected from their depots.
This funding is often utilised to purchase much needed computers and other
equipment.

An amazing fact about using cullet (recycled glass) is that there are no
fusion losses in the melting process. In other words one ton of cullet will
generate the ability to remake one ton of bottles. In contrast it takes
approximately 1.2 tons virgin batch material to manufacture 1 ton of glass.

What is Recyclable Glass?

In essence all glass bottles and jars are recyclable through the glass
packaging furnaces. Plate/Flat glass is recyclable through other companies.
Materials that are not recyclable through Consol are:

Ceramic cups, plates and pottery
Clay garden pots
Laboratory glass
Crystal and opaque drinking glasses
Mirrors, windshields and window glass
Heat-resistant ovenware (for example, Pyrex or Visionware)
Light bulbs

Before recycled glass is melted, the following contamination is removed
through processing:

Ceramic and wire caps for beer bottles
Lead collars from wine and champagne bottles
Stones and dirt
Metal caps, lids and neck rings
Collections

Glass is collected throughout Southern Africa and bought by the Glass
Packaging Industry. For further information on your local collector/agent
please contact the Glass Recycling department on 011 874 0000. Collections
are performed through appointed agents. As part of an awareness initiative
stakeholders in glass recycling have invested in 1,200 bottle banks in urban
towns throughout South Africa to assist in domestic recoveries.

Consol's Involvement Consol Glass has many planned activities to aid in
increasing the volumes of recycled glass. Some of these are highlighted
below:

Township Growth

There are currently 40 formal glass collecting agents in Gauteng townships
collecting no less than 500 tons per month. Through further investment and
links with government department Consol intends on providing more
entrepreneurial opportunities in growing this market to even greater
heights. Expansion into the Western Cape and Greater Durban areas are to be
initiated.

Kerbside Collections

Consol will be analysing the possibility of performing domestic kerbside
collections. With the possibility of government legislation being imposed
onto glass separation at source may be implemented to assist.

Statistical Performance

Currently the Glass Packaging Industry, Consol Glass and Nampak Glass,
produces glass sales of 540,000 tons per annum. Of this around 105,000 tons
(20%) is recovered and recycled. A statistical graph at
http://www.consol.co.za/html/glassrecycling.htm shows the historical trend
over the past 16 years.
