How it works
A top-loading batch machine. Waste goes in through the lid — by hand, by digger, or by hydraulic bin tipper — and burns in a primary chamber lined 180 mm deep in high-alumina firebrick rated to 1,450 °C. Above it a secondary chamber holds the flue gases at a minimum of 850 °C for two seconds before anything reaches the stack.
On an island property that second chamber is the part that matters. The plant sits within sight and smell of guest accommodation, and two seconds at temperature is what stands between a working waste room and a complaint.
It runs one load a day. Waste is loaded before the burn rather than topped up during it, and the ash — about 3% of what went in — is cleared before the next load. That daily rhythm is what a waste room has to be sized around, so it is the figure to check your own volumes against before choosing between this and the larger TB.
- A primary chamber lined 180 mm deep in interlocking high-alumina firebrick over insulation board and insulating brick — the multi-layer lining Addfield credit for a 40% cut in fuel consumption against comparable machines.
- A pre-cast block impact zone in the loading chamber, taking the hit of loading so the refractory behind it does not.
- A counterbalanced lid insulated with refractory fibre: light enough to work by hand, and sealing tightly enough to keep the heat in the chamber.
- A secondary chamber holding the flue gases at a minimum of 850 °C for two seconds, with its own burner, air fans and temperature sensor.
- Temperature-controlled burners on both chambers, switching against that sensor rather than running continuously.
- A control panel with push-button and touch-screen operation, pre-programmed and adjustable on site.
- 8 mm and 10 mm seam-welded mild steel casing, finished in a two-pack paint system.
Built to order, not standard supply
- Bin tipper — electro-hydraulic, lifting and tipping over 150 kg so a load goes in hands-free.
- Fuel tank, 1,000 to 5,000 litres, for a site with no permanent fuel supply or as a backup to one.
- Data logging on the control panel, where burn records have to be kept automatically.
- De-ashing doors, mechanically loading lids, and alternate loading arrangements, built to order.
Addfield builds these to order. Ask GreenWave for them at enquiry — they are specified before the machine is made, not fitted afterwards.

Case study · Addfield · 2021–22
Environmentally sustainable incineration in the Maldives
Addfield’s own account of putting SB and TB incinerators onto Maldivian resort islands. It is worth reading for the conditions rather than the sales copy: resort waste arrives mixed rather than as the single stream these machines are usually specified against, so the commissioning visit in February 2022 was spent tuning the burn for that mix — and on an island where smoke or odour reaches the guests, that tuning is the difference between a working plant and a complaint.
