Recycling Issues on Glass

• Glass is 100 recyclable.

• But, there should be color segregation to produce
  predictable color of products.
• Clear
• Green
• Amber
• Blue
• As much as possible, they are not soiled in order
  not to contaminate the end product

7

Recycling Issues on Glass

• Recycling
• Waste glass bottles (easy batch preparation)
• Cheap
• Melting Temp. about 1450oC
• Lower fuel consumption

• New Batch
• Silica sand
• Soda ash
• Limestone
• Colorants
• Feldspar
• Expensive
• Melting temp. gt1550oC
• High fuel consumption

Hand Blown Glass

• Basic Equipment
• Melting Furnace
• Annealing Furnace
• Fuel Tank
• Molds
• Blowpipes
• Quite high investment but products have export
  potential

11

The Melting Furnace

• Tank Furnace
• 750 kgs holding capacity
• Continuous operation
• lined with Fused Cast Zirconia
• Bunker oil fuel
• Firing temp. 1450oC at the melting end and
  1100oC at the blowing end

Annealing
Putting the formed products in an annealing
furnace at 550oC to remove internal stresses and
therefore prevent cracking of the products.

Economic advantages

• Employment generation (skilled labor dependent)
  in support to the Presidents agenda on
  employment generation
• Waste recycling thus cleaner environment
• Ideal for barangay MRFs for proper
  implementation of R.A. 9003
• Decorative and export potential products

31
ITDI Programs for Implementation of Glass
Recycling

• Training and Demonstration
• Technology Business Incubator
• Technical Assistance in Setting up of production
  facilities
• Contract Research

32
Final Words

• There is CASH in TRASH.
• Lets RECYCLE and take care of our ENVIRONMENT!
