It is a sight which dominates the skyline and now dominates Suffolk’s claim to be the greenest county.

Every single bag of general refuge from households and businesses in the county is going to a £180million incinerator plant in Great Blakenham, near Ipswich – preventing any rubbish going to landfill.

The burning process creates enough energy for electricity to be pumped to 30,000 homes and saves taxpayers £8million a year through cutting landfill taxes, according to Suffolk County Council.

Around 50 lorries a day arrive filled with rubbish to be burnt. It is first dumped in a 45ft deep bunker before it is mixed and sent to two huge incinerators.

Due to the automated systems, few staff out of a total 47 are needed on the factory floor – with several colleagues in a control room monitoring the operation.

The systems prevent any rubbish from entering the incinerator if it is not up to at least 850C (1562F) – with a maximum desired heat of 1100C (2012F).

Any rubbish which cannot be burnt into gas is then either reused to help build roads or recycled if metal. This means the plant produces no unusable waste. The only emission is mainly steam coming out of the plant’s two 81.5metre chimneys. Gases, which are also emitted, are closely monitored for their levels of harmful pollutants.

Lime, activated carbon and urea are used to help neutralise the pollutants – with dust emissions prevented by a revolutionary filter system.

The plant is operated on the county council’s behalf by SITA UK which manages another four in the country – with a further three under construction.

Paul Leighton, plant manager, said: “The plant is designed for a maximum of 269,000 tonnes of waste a year, with Suffolk and Norfolk’s waste we have about 214,000 tonnes a year. That leaves some 50,000 which needs to be sourced.

“Waste flows are increasing historically and the contract allows for Suffolk County Council to increase capacity; we expect to see some growth on the 214,000 tonnes from Suffolk and Norfolk in the future.”

In recent weeks, Great Blakenham residents have voiced concerns over a lack of infrastructure in the area compared to the number of new homes. But Mr Leighton said the response to the plant had been positive.

“I honestly think it’s been very good, I think Suffolk County Council communicated very early on about the facility, I think they’ve done a really good job,” he said.

“A community liaison group meets on a monthly basis and can have a look around and air any concerns that they may have. 
That group has been going for three years and I believe it still has good attendances.”

Around 170,000 tonnes of rubbish comes from Suffolk – with 40,000 tonnes from Norfolk. And waste can only come from counties in the east, as set down in planning regulations.

Two huge greenhouses, which are set to be built nearby, would be connected to the plant for its heat. They would cover an area of almost 50 acres and produce 7,500 tonnes of tomatoes a year.

Manda Henry, from SITA UK, was asked what long-term future the plant has if Suffolk’s recycling rate increases. She said: “There is a 50% recycling rate in Suffolk which is very good but we are still striving to increase it – recently the number of items which can be recycled increased and included things like Tetra Paks – but inevitably there’s stuff left over and the days of burying things in the ground are no longer.

“If the amount coming from households decreases then that will decrease the overall amount but that’s not allowing for business waste – shops and supermarkets on the high street have to deal with waste, we are not talking hazardous, but general waste.

“Years and years ago using landfill was reasonable option, now-a-days it’s just not and we had to find something better and that’s what this plant does.”

The plant can operate 24 hours a day, 365 days a year. Bosses 
expect it to close completely for around three days a year for maintenance.

  • Tour of Suffolk’s new £180million energy- Before reading the article, my first reaction was to put my name down for this tour. Very ambiguous title As a previous comment, who gets the tour then ?

  • It seem a pretty good way of getting rid of non recyclable material and it is saving a fortune Electricity produced is worth about £6M a year The saving in Landfill Tax about £14M a year The value of tomatoes produced at farm prices about £1M An unstated amount of residual waste will be used in road construction and any residual waste metals sold for recycling May even be able to use some more of the waste heat for local heating system for homes

  • Unclear who is getting a tour. Can we all come and look? I think the only thing that stopped Norfolk was that they represented the wrong political party and when the government found out they took money that had been promised away. Tory Suffolk didn't have that problem. If that isn't what happens perhaps someone can explain what did happen.

  • I know think "pumped" is the correct term for the dissemination of an electricity supply. Liquids can be pumped, gases can also be pumped, but electricity most certainly cannot. "Distribution" would probably be the most appropriate term in this context.

  • Is this the sort of place that some in Norfolk wanted but ended up with a big financial disaster ?
