Rotowaro Carbonisation Plant
Many of you may have seen images from this site. Today however, I decided to put my Mavic Air to it's biggest test yet. From the roadside, I sent it in to gain a different perspective that I have been yet to see. The high altitude, distance and wind was no match for the drone.
The first of its kind in the Southern Hemisphere, the plant was constructed in the late 1930's to convert otherwise unusable low-quality coal from the nearby Rotowaro Coal Mines into carbon briquettes, which were then used for domestic heating. The coal was carbonised using the Lurgi process, the result being coke and charcoal, with tar and creosote as by-products. The tar was used with the char to create the briquettes. Waste from the plant was discharged directly into the nearby Awaroa stream, which caused heavy pollution of the waterway. Following complaints about the pollution, Waikato Carbonisation Limited trialed a waste incineration programme, but the output of the plant exceeded the capacity of the burners. The excess was pumped into waste pools up until the plant's closure in 1985, when major fire caused a retort to explode.
Various ownership changes lead to the complete abandonment of the plant. The plant currently sits on land administered by the Public Trust.
