Grundon and APP make presentations to SEPA and Perth & Kinross Council

At two separate meetings, Grundon Waste Management and Advanced Plasma Power Ltd (APP) – the proposed technology supplier for the gasification plant on Shore Road Perth – have briefed the Scottish Environment Protection Agency (SEPA) and Perth & Kinross Planners and Environmental Health Officers about the technology.

Following a review of the issues raised by interested organisations and individuals – and the comments made by the Scottish Government Reporter at the end of 2010 – Grundon revised its reserved matters application for an energy from waste facility at Shore Road.  The company also looked at the most up to date advice from SEPA and the Scottish Government – where the 2010 Zero Waste Plan acknowledges the significant role of energy from waste.

The new reserved matters application, which was registered by the council in June, addresses all of these issues by adopting a different technology.  The APP gasification process takes two well established, well proven technologies – gasification and plasma arc – and combines them into a Gasplasma® system.  This turns waste into sustainable power and creates useable by-products such as secondary aggregates.  Gasplasma® is not an incineration process as it does not burn (combust) the waste, it uses heat and ultraviolet light to convert waste to a high quality fuel gas (syngas) to generate non-fossil fuel energy.

Martin Brooks, Engineering Director for APP, explained the three stage process to attentive audiences at both meetings.

“The input to the plant would be a pretreated, refuse derived fuel produced off site, dried into a ‘floc’ material.  This is gasified in a fluidised bed gasifier, producing solid chars and ash, as well as a syngas, which at this stage still contains tars and soot.

“We then use a plasma arc convertor – used in other industries, for example to separate platinum from old catalytic converters as well as in steel production – to crack the impurities in the syngas and clean it up.  At the same time the ash and the inorganic elements are vitrified – turned into a glass-like product known as Plasmarok®.  This is used, for instance, as a secondary aggregate to replace the extraction of primary materials being quarried for construction jobs.

“Finally, the clean gas powers gas engines which generate secure, clean, local heat and power”.

Grundon’s Director of Estates Bob Nicholson explained to SEPA and council representatives that the change in technology means that instead of one large building, the process would be accommodated in a series of smaller buildings.  The stack height would be reduced to 34 metres from 80 metres and the tallest building to 18.5 metres from 34 metres.

“The new scale, design, appearance and layout mean the proposed development would be a similar size to other buildings in the local area.  It would be screened from views to the west by the prison complex and to the north by the existing 25 metre tree cover in South Inch Park.

“We have also redesigned the layout so the significant noise generating plant would be in a fully enclosed building at the north of the site, furthest away from the prison”.

Martin Brooks explained many other noise reduction techniques and took several questions from representatives on this and other technical elements of the Gasplasma® process.

Rolf Stein, Chief Operating Officer of Advanced Plasma Power says,

“Our main focus is to provide the best solution for the people of the City of Perth.  We have worked with Grundon to provide a Gasplasma® energy from waste solution that turns local waste into local renewable power and heat and meets the needs of the local community at the same time”.
