Strictly, no. Renewable is usually applied to something like the energy from sunlight or wind, which is still there tomorrow even if we use it today.

However, glass is made from silicon (very clean sand, but not rare) with a mixture of added chemicals (soda, lime, antimony oxide etc) to improve the quality. Calumite is also usually added.

And of course an important ingredient now is cullet, which is broken recycled glass, which makes glass somewhatrenewable.
