How to Dispose of Fish Tank & Aquarium
- 1Fish tanks and aquariums are manufactured from tempered or plate glass with different melting points from bottle glass, strictly prohibiting them from curbside glass recycling bins.
- ✓Small tanks under 45cm should be wrapped in protective cardboard and discarded in non-combustible PP bags, while large aquariums (60cm or larger) require municipal bulky waste disposal permits.
How to Dispose (5 Steps)
- 1
Complete Drainage and Component Separation: Drain all water, relocate living aquatic life and plants responsibly, and disconnect all gravel, substrate, heaters, canister filters, and LED lighting so only the bare aquarium tank remains.
- 2
Dedicated Disposal for Substrate and Electric Gear: Route motorized filters, submersible heaters, and air pumps to designated small e-waste collection bins; thoroughly sun-dry all gravel, sand, and soil substrate before sealing inside heavy-duty non-combustible waste sacks.
- 3
Determine Disposal Classification by Tank Dimension: Designate compact tanks (under 45cm/18 inches) or shattered glass shards for non-combustible PP trash bags; classify large displays (60cm/2-foot or larger) and aquarium stands as municipal bulky waste requiring permit stickers.
- 4
Safety Cushioning and Non-Combustible Bagging: Apply heavy packing tape across all glass panels in an 'X' pattern to prevent shattering hazards, wrap the perimeter in thick corrugated cardboard or bubble wrap, and seal tightly inside a municipal non-combustible sack.
- 5
Bulky Waste Permit Booking and Curbside Placement: Register online via your municipal district office website or purchase a bulky disposal sticker ($5–$15 / ₩3,000–₩10,000) at local convenience stores, attach the receipt permit firmly to the glass, and place curbside on scheduled collection days.

Frequently Asked Questions
Q. Why can't I place an unbroken glass aquarium into the curbside glass bottle recycling bin?
A. Aquarium walls are fabricated from specialized float plate glass or tempered glass engineered to withstand hydro-pressure, which has a drastically higher melting temperature and different chemical viscosity than soda-lime container bottles. When plate glass enters a container recycling furnace, it fails to melt completely, creating insoluble crystallization defects that ruin thousands of newly manufactured bottles. Even crystal-clear fish tanks must be routed strictly to non-combustible bags or bulky waste pickup.
Q. Can seamless clear acrylic plastic nano tanks go into standard plastic recycling?
A. Yes, compact desktop tanks made purely from rigid acrylic (PMMA) can be deposited into plastic recycling bins once rinsed clean. However, if the tank features glued silicone seals, rubber foot pads, integrated LED wiring, or composite divider plates that cannot be dismantled, sorting facilities reject it as contaminated mixed waste, requiring disposal in municipal general waste or non-combustible sacks.
Q. What is the typical municipal sticker fee for a 60cm (2-foot) aquarium in Korea?
A. While municipal ordinances vary slightly by district, standard sticker fees range from ₩3,000 to ₩5,000 ($3–$5) for 45–60cm medium aquariums, and ₩7,000 to ₩10,000 ($7–$10) for 90cm (3-foot) or larger display tanks. Dedicated wooden cabinets or aluminum extrusion profile stands must be registered separately as bulky furniture items (₩3,000–₩5,000).
Q. Is it permissible to discard used aquarium soil, sand, or gravel onto apartment flowerbeds or local park grounds?
A. No, dumping aquarium substrate onto public greenery or private community landscaping constitutes illegal waste dumping punishable by fines up to ₩200,000. Nutrient-rich aquatic plant soils and calcified coral sand severely distort natural soil pH and drainage dynamics. Always air-dry substrate completely under sunlight before sealing it legally inside a municipal non-combustible PP bag.
