Which of the following is true about glass recycling?
a.
recycling glass reduces the rate of deforestation.
b.
recycling glass eliminates greenhouse gas emissions.
c.
recycling glass is an energy-saving practice.
d.
recycling glass has an incredibly short turn around time.

C

Explanation:

Melting of recycled glass requires less energy that the making of new glass that involves heating of quartz sand at a higher temperature. The energy saved can be approximately 10 %- 15% which may seem meager but on a large scale will be significant.

c.  Recycling glass is an energy-saving practice.

Explanation:

Recycling is a process of transformation and conversion of a used product into a reusable form. Glass is a super cooled liquid which remain in the molten to solid state. The production of glass is a very time consuming and thermal energy dependent process. On preparation of glass it is rapidly heated and cooled at extreme temperatures. Recycling of glass will save thermal energy as less of amount of heat will be required to transform one glass product into another.
