According to our Spanish Friends who make these glass products:
Every time a bottle is recycled enough energy is saved to light a 100W bulb for 4 hours.
Glass is the ideal “green” material – it can be recycled again and again, and does not deteriorate with recycling.
Each tonne of recycled glass saves 1.1 tonne of raw materials, and recycled glass requires about 40% less energy to produce than new glass.
