Want to go green but always hesitate in front of the recycling bin? Correct sorting is actually the core of upcycling. Once you learn to identify the four common types of plastic below and master some basic cleaning tips, you can effectively take part in resource circulation. For the most common No. 1 PET bottles, you can even enjoy an exclusive door‑to‑door collection service via the ECOHOPE APP.

Four common plastics: identification, handling, and “rebirth” potential

● No. 1 PET: The most valuable “fibre black gold”

Common uses: Mineral water bottles, tea drink bottles (clear bottle bodies).
Handling steps:
1. Twist off the cap (usually No. 5).
2. Remove the sleeve or label.
3. Rinse the inside and flatten the bottle.
Upcycling potential: After proper processing, PET can be drawn into fibres to make rPET eco‑fabrics, which can be transformed into stylish functional clothing or corporate uniforms.
Dedicated collection service: These bottles can be scheduled for door‑to‑door pickup directly through the ECOHOPE APP.

● No. 2 HDPE: The tough and durable “circular workhorse”

Common uses: Shampoo bottles, body wash bottles, dishwashing liquid containers.
Handling steps: Since these containers are thicker and contain detergents, be sure to thoroughly rinse away any residue and leave them to dry completely.
Upcycling potential: Recycled HDPE is suitable for making sturdy phone stands or durable household accessories.

● No. 5 PP: The heat‑resistant “all‑round fighter” in daily life

Common uses: Takeaway food boxes, bottle caps, contact lens blisters.
Handling steps: Cleanliness is critical. Oily takeaway boxes must be washed with dish soap. If grease remains, it can cause odours and lower the quality of the entire batch of recycled material.
Upcycling potential: PP can be upcycled into high‑quality Eternality Pens, office organisers, or eco‑friendly furniture.

● No. 6 PS: The “difficult challenger” seeking a second life

Common uses: Model frames, foam packaging (styrofoam), some disposable containers.
Handling steps: PS is brittle and bulky, so remove non‑plastic attachments (such as stickers and tape) before recycling, and make sure there is no food residue.
Upcycling potential: With specialised technology, PS can be turned into recycled construction materials or refined decorative frame components.

“Zero‑failure” recycling in three steps: Wash, Dry, Book

To keep upcycling flows smooth, complete these three simple actions before you recycle:

Wash: Remove leftover food and grease as thoroughly as possible. This keeps the material clean and increases its recycling value.
Dry: Let items dry to avoid moisture that can foster bacterial growth or mould during storage and transport.
Book (via App): Once you have collected enough No. 1 PET bottles, open the ECOHOPE APP and book a door‑to‑door collection with a single tap.
