Recycle of Scrap Glass

A glass is highly recyclable. Thanks to this feature, in the future government and the society certainly

will support the use of glass as packing material due to environmental concerns. TGI§s flat glass factories
use recycled scrap glass in production. In addition to recycling scrap glass, TGI also recycles all the
reusable packaging material in the production process. Not only does this reduces cost, it also reduces our Sustainable TGI
environmental impact and fulfills our corporate social responsibilities.
TGI§s container factory recycles its blemished and scraped products, which reduces the consumption
of ore and the environmental impact. Recycle yards recycle scraped glass products and ship them to the
Hsinchu Factory. These recycled products will be selected, washed, smashed and screened before being
used as raw materials for production. Recycling reduces waste and consumption of ore, which benefits the
environment. A scraped glass is not considered as waste in the glass industry. Instead, it is the material About TGI

needed for production. Glass containers are the type of product most consumers are familiar with and the
most demanded product in the glass industry. Therefore adding scraped glass into the molten glass is both
beneficial environmentally and economically.

Each TGI§s factory improves its energy efficiency in the production of glass, through a furnace heat
storage exchange chamber and the best available control technology, with energy-saving kiln oxyfuel
specific measures to reduce the operating costs in terms of environmental impact. Various types of energy
consumptions are as follows:
