A new high capacity general waste incinerator

High Capacity incineration plant supports plastic waste management in remote locations

The Ascension Islands, a remote volcanic island located just south of the equator. Having no permanent residents yet a rotating population of approximately 800 people. Managing waste securely has become a growing issue previously managed by being burned in an open heap with any residue that didn’t burn sent away to landfill.

Apart from being very bad for the environment, this approach was far from sustainable especially with the growing awareness of the dangers of plastic waste. Being surrounded by so much ocean and limited land solid waste was becoming a very serious issue that needed to be addressed to prevent damaging the environment on and off the island. As such in early 2017 we were approached by the Government of the Ascension Islands to begin developing a reliable solution.

Recognising our expertise in the field gained after previously delivering waste solutions for several similar islands already. We were perfectly suited to deliver the appropriate solution to manage the destruction of all the waste produced. Even with a relatively manageable population manmade waste has to be disposed of carefully to prevent potentially hazardous contamination. An installation such as this needs a machine that is specially optimised to handle the full mix of the waste generated on the island.
As highlighted by the BBC show, The Blue Planet plastic waste is delivering a very real threat to our worlds oceans, every step that can be taken to prevent waste ending up in the sea is one taken in the right direction.
This is especially the case for remote locations lacking the infrastructure and space found in larger communities. Still needing safe, sustainable ways to manage the waste that is created on a daily basis. Where a landfill site is not possible taking up valuable space and impacting the local environment the only previous safe alternative is to ship their waste to neighbouring islands.

The G250 is able to continuously process up to 250kg of waste through its automatic loading systems.  The primary chamber has a stepped hearth to regularly move the waste through the process allowing safe continuous loading throughout the incineration process. 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.

Located in such a remote position 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 quickly and easily be repaired compared to concrete cast refractories.  Any problems in the future with a brick refractory can be managed in a matter of days whereas a fault in a concrete cast refractory could put such a large machine in such a remote location out of action for months if not longer.

This installation has been another fantastic journey for all of us here working closely with the Government of the Ascension Islands through regular teleconferencing 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.
