Volume comparison: trailer loads vs bin size
As a rule of thumb, 1 bin m³ ≈ 1 standard 6×4 trailer load. A 15m³ bin holds what 15 full trailer loads do. To empty a 15m³ bin worth of waste via DIY, you'd need 15 separate trips to the tip.
| Bin size | Approximate trailer loads | Trailer rounds needed |
|---|---|---|
| 9m³ Standard | ~9 loads | 9 tip runs |
| 12m³ Medium | ~12 loads | 12 tip runs |
| 15m³ Large | ~15 loads | 15 tip runs |
| 20m³ XL | ~20 loads | 20 tip runs |
| 30m³ Maxi | ~30 loads | 30 tip runs |
| 40m³ Super | ~40 loads | 40 tip runs |
Time: the hidden cost of DIY
One tip run costs you time: loading the trailer (30–60 min), driving to the tip (15–45 min depending on distance), unloading (15–30 min), and driving back. That's 1.5–2.5 hours per trip, round trip.
For a 15m³ project, 15 trips × 2 hours = 30 hours of your time, spread across your project. Add multiple crew members and the total labour hours climb fast. A hooklift bin removes this labour entirely — you load at your pace, we collect once.
Fuel and vehicle wear
Each tip run costs fuel. A typical 6×4 trailer and tow vehicle averages 10–12 litres per 100km. If your local tip is 20km away (40km round trip per trip), that's 4–5 litres per run at current fuel costs. Over 15 runs, that's 60–75 litres of fuel.
Vehicle wear is real: suspension, tyres, brakes all degrade faster with repeated loaded trips. Trailer wear compounds this. These costs are hard to quantify but significant over time.
15 DIY tip runs = 30 hours labour + 60–75 litres fuel + vehicle wear. A single $1,450 bin removes all of it.
When DIY genuinely wins
- Tiny loads (1–2 trailer loads): one or two tip runs is faster than booking a bin.
- Very close to a tip: if you live next to a transfer station, time and fuel are minimal.
- Off-peak hours available: if you can make quick trips during quiet times, scheduling is easier.
- Hazardous or restricted waste: some materials (e.g. recycling that doesn't go in bins) must go to the tip anyway.
When bin hire wins
- Any load larger than 2–3 trailer loads: the maths favour a bin quickly.
- Full renovations or demolitions: 10+ trailer loads = a bin is cheaper and faster.
- Concrete or soil: heavy materials weigh a trailer down fast, making multiple trips necessary.
- You value your time: 30 hours of labour is worth money, even if you're not billing it.
- Poor site access: if loading from a house or site is awkward, a bin lets you work at your pace.
