WATCHING fragrances and food flavourings being produced has failed to reassure residents that an extraction plant should be given the go-ahead next Monday.

Scientists at Ineos Fluor have become the first in the world to develop a pioneering method of extracting unique properties from exotic raw materials like jasmine and vanilla.

Residents fear changing the Xentia Technology site from light to general industrial could attract more manufacturing to the Heath.

Diane Nowell, said: "We are afraid that a new industrial complex will grow once again. We don't want more noise, dust, smells - even those of jasmine, lavender and vanilla."

Another resident, said: "It's the thin end of the wedge. There are more than 80 companies on this site, how do we know others won't follow suit?"

Ineos invited two groups of 10 residents to visit the proposed site yesterday (Tuesday).

"Seeing this site is not going to change much," said one resident.

"We know it is a small plant but sticking it in a business park in a big residential area is not on."

An Ineos spokesman, said: "We do understand the community's concerns. We are listening to what they have to say.

"This is not a chemical plant, it is much closer to food production. It is so gentle and innocuous, they won't see anything."

Expert scientists, they say, are on hand to develop the fledgling plant as the company now wants to test the market.

Eight letters of objection, supported by Halton MP Derek Twigg and a 50-signature petition have been submitted to councillors.
