Prosecutors in Taoyuan have indicted a construction boss and eight others for burying construction waste under a road at an army training ground, and are trying to claw back a huge illegal profit.

• A contractor claimed he was laying recycled gravel on a service road at the Hukou training ground, but filled it with construction waste instead.
• Prosecutors say fake "recycled product" purchase contracts were signed with several firms to disguise where the material came from.
• He then charged those firms high waste-disposal fees, dressed up as transport or handling costs, earning about NT$1.3 billion illegally.
• Digging at the site in April turned up broken bricks, tiles, scrap plastic pipe, waste metal, old wiring, styrofoam and concrete chunks mixed into the road.

Outlook: Nine people and six companies now face trial, and the military test center and the firms have been ordered to submit a cleanup plan to restore the site.
