Clean, sort, earn: preparing recyclables for the best price

Ask any seasoned recycler what makes the difference between a small payout and a satisfying one, and they won't talk about the rate. They'll talk about preparation. Clean, dry, well-sorted material is worth more, sells faster, and keeps the whole recycling system working. Here's how to prepare your recyclables like a pro.

The three rules that matter most

Recycling value comes down to three habits, in this order: Clean. Sort. Dry. Get these right and everything else follows.

1. Clean

Contamination — food, liquid, oil — is the biggest destroyer of recycling value. A single dirty container can spoil a whole bag.

• Empty every bottle, can and container completely.
• Give a quick rinse to remove residue. You don't need spotless; you need food-free.
• Scrape off stuck-on food from tins and tubs.
• Skip anything greasy that can't be cleaned, like an oily pizza box lid.

2. Sort

Recyclers pay for clean, single-material streams. A mixed bag is downgraded because someone has to separate it again.

• Keep separate bags for plastic, paper/cardboard, cans and glass.
• Within plastics, separate clear PET bottles from coloured and from film if you can.
• Don't bury a few cans inside a bag of paper — keep streams distinct.

3. Dry

Water is the enemy of paper value. Wet cardboard weighs more briefly but is rejected or downgraded, and damp conditions breed mould and odour.

• Store paper and cardboard somewhere covered.
• Let rinsed bottles and cans drain before bagging.
• Never leave recycling out in the rain before a buyback day.

Material-by-material prep

• PET bottles: empty, rinse, cap on, squash flat. Squashing saves space, not value.
• HDPE bottles: rinse out milk and detergent residue thoroughly.
• Cardboard: flatten boxes, remove tape and polystyrene inserts, keep dry.
• Office paper: keep it clean and separate from newspaper for a better grade.
• Cans: rinse, and crush aluminium to fit more per bag.
• Glass: keep bottles whole, remove lids, separate by colour where possible.

Build volume the smart way

Because buyback pays per kilogram, a bigger load means a bigger payout. The trick is to store clean material between buyback days:

• Keep a dedicated, dry corner or a few stackable bags or boxes.
• Squash and flatten as you go so storage stays compact.
• Aim to bring a full, well-sorted load rather than a few odds and ends.

For collectors who do this for a living, organised storage and a regular routine can double the value of a week's work.

Avoid these costly mistakes

• Bagging wet recyclables — the fastest way to lose value.
• Hiding rubbish in recycling — nappies, food and polystyrene contaminate everything.
• Mixing streams — convenient for you, costly at the scale.
• Leaving liquid in bottles — adds rejected weight and mess.
• Forgetting to flatten — you carry less and make more trips.

Why preparation helps everyone

When material arrives clean and sorted, it moves faster through our facility, bales to a higher quality, and fetches a better price from mills and reprocessors. That better price flows back to you as a stronger rate, and it keeps more material economically worth recycling. Poorly prepared loads, by contrast, slow everything down and push material towards landfill.

A simple weekly routine

1. Rinse bottles and cans as you finish them.
2. Drop each item into its labelled bag.
3. Flatten boxes and squash bottles.
4. Store everything dry.
5. Bring a full, sorted load to your next buyback.

Master this and you'll notice the difference in your very next payout. Preparation is the quiet superpower of profitable recycling — and it costs nothing but a few good habits. Find your nearest buyback point and put these tips to work.
