Explanation

Ranked by moisture, dry trash holds the least, then rubbish, then refuse, with wet garbage holding the most.

Trash is dry material like paper, glass and metal with almost no moisture.

Rubbish mixes combustible and non-combustible dry solids and stays fairly dry.

Refuse is a broader term for mixed solid waste with moderate moisture.

Garbage is decomposable food and kitchen waste, which is high in moisture.

Wet garbage rots quickly and needs prompt collection to control odour and pests.
