What is the difference between rPET, cardboard and glass?

In this article, we will look together at a comparison of materials, specifically rPET, cardboard and glass, from different aspects of ecology and ease of use.

Transport and energy used for transport

• rPET – Light material, less weight per volume. Less energy consumed for transport – 13.7 MJ / kg needed to transport an average plastic beverage.
• Cardboard – The shape of the bottle is suitable for efficient transport.
• Glass – 25.4 MJ / Kg is needed to transport the average beverage in the glass.

Recyclability

• rPET – 100% recyclable. The bottle, lid and etiquette are made of materials that are easy to separate and recycle.
• Cardboard – 100% recyclable. Materials separation is required. The main problem = aluminium.
• Glass – 3 materials, an aluminium lid and a plastic or paper label that needs to be separated.

Energy needed for recycling

• rPET – 53,91 kJ is used to recycle one plastic bottle.
• Cardboard – 330 kJ are needed to recycle one multi-layer carton (1L).
• Glass – 565,8 kJ is used to melt one bottle.

Emissions saved by recycling

• rPET – One ton of recycled plastic will save 1,350 kg of CO2.
• Cardboard – One ton of recycled cardboard will save 650 kg of CO2.
• Glass – One ton of recycled glass will save 315 kg of CO2.

Usage and fragility

• rPET – High material durability, does not need padding for transport to prevent damage. Easy to carry.
• Cardboard – It does not need padding for transport to prevent damage. Easy to carry.
• Glass – Fragile, glass requires secondary packaging to protect the material. If broken, waste will be generated from the packaged food and there is a risk of injury. Heavier material, more complicated carrying.men
