Ascension Islands Case Study - 1

Highly efficient solution for safely processing solid waste. Addfield G250 High Capacity Incinerator. The Ascension Islands, a remote volcanic island located just south of the equator. Having a rotating population of approximately 800 people. Managing waste securely has become a growing issue previously managed by being burned in an open heap, any residue that didn’t burn was sent away to landfill. Far from sustainable, especially with the growing awareness of the dangers of plastic waste. Surrounded by so much ocean and limited land, solid waste was becoming a very serious issue needing addressing. In 2017 we were approached by the Government of the Ascension Islands to begin developing a reliable solution. Recognising our expertise in the field after previously delivering waste solutions for several other islands. An installation such as this needs a specially optimised machine to handle the full mix of the waste generated. Especially the case for remote locations needing safe, sustainable ways to manage the waste that is created on a daily basis. The best solution for treating the range and quantities of waste to be disposed of would need almost continuous processing. We proposed our G250 high capacity facility, housed within two stacked 40ft containers, reducing the need for additional civil works required on site prior to installation. Producing a self-contained solution that can be simply placed into position ready to be commissioned and operated. This enables a rapid and easy installation. An ideal solution for remote projects, the containers reduce the challenges of installation, handling and logistics all in one go. Able to continuously process up to 250kg of waste an hour through its automatic loading systems. The primary chamber has a stepped hearth to regularly move the waste through the process allowing continuous loading throughout the incineration. The G250 is able to deliver a clean incineration of mixed waste types through having a large cylindrical secondary chamber with a two-second retention to ensure that only clean flue gas is returned to the environment. Our team of engineers arrived at the Ascension Islands to begin the 4 week process of commissioning and delivering a full range of training to ensure the Islanders were able to operate and maintain the facility for the future. Quality and reliability were essential factors in the decision making process. Our brick lined refractory, delivers incredible insulation, it also ensures that any damage from loading and sustained usage can rapidly be repaired compared to concrete cast refractories. Any problems can be managed in a matter of hours whereas a fault in a concrete cast refractory would put such a large machine out of action for weeks. This installation has been another fantastic journey working with the Government of the Ascension Islands through regular tele-conferencing as well as their QA inspectors. A testament to the quality of the design and manufacture of our machines to have been trusted with such an important project.
