Synthetic resins are divided into two classes:

• thermoplastic resins – they remain plastic after heat treatment,

• thermosetting resins – they become hard and not flexible after heating. 

Synthetic resins are not clearly differentiated from plastics.

Epoxy resin is a super strong adhesive, resistant to both heat and chemical exposure.

Epoxy resin is a mixture of organic and inorganic components, most of which are toxic to the human body and to animals. 

Epoxy resin is not biodegradeable, it can not be reprocessed, repaired, or recycled. 

Cured (hardened) resin can be disposed of in regular rubbish. However, it might leak when mixed with other waste in the landfill, and thus there is a risk of polluting soil and water. It is better not to dispose resin in a liquid state, as the risk of water pollution is even higher. It is recommended to leave the resin exposed to sunlight for several days until it hardens – and only then dispose of it with regular waste. In short, the disposal of epoxy resin is a big problem. So if possible, choose more sustainable options.
