MATERIALS HANDLING
analysed on site as they arrive to check compliance, followed by the distillation process which transforms the liquids into new products for industry use depending on the liquid type.
THIN FILM EVAPORATOR The company also uses a ‘thin film evaporator’ to separate the components of a process liquid based on volatility. The basic method involves applying heat to a liquid which causes it to evaporate, thereby leaving the less volatile substance behind. The more volatile, and now gaseous, substance is then condensed and collected at a separate location. Traditionally, batch or continuous
processes such as natural/forced circulation, falling and rising film, and climbing and falling plate evaporators have been used successfully with a range of process liquids. However, these evaporators have proven to be inefficient with high-boiling, viscous, fouling, and heat sensitive liquids. The company claims that this
solvent recovery process will save an estimated 172,000 tonnes of CO2e in greenhouse gas emissions each year, equivalent to taking 78,000 diesel cars off the road annually.
Veolia has built new distillation columns at the Garston energy centre
The Garston site turns waste materials into high-quality recycled products The energy centre in Garston uses
a distilled product fuel, produced on site, to power the steam boilers, reducing the energy required from gas by 10,000 MWh per year, equivalent to the gas usage of 1,000 homes per year.
VEOLIA’S STRATEGIC PLAN The expansion is part of the facility’s new strategic plan called GreenUP which aims to make Veolia a champion of decarbonisation, de-pollution and regeneration of natural resources. The site processes waste materials to regenerate them into high-quality
recycled products that can be reused, thereby displacing virgin materials in the supply chain.
FUELLED BY RECYCLED MATERIALS As well as generating recycled products, the plant also produces several types of fuel. As mentioned, a distilled product fuel is used instead of natural gas to power the site’s steam boilers. Other by-products from the process are sent to Veolia facilities to be manufactured into alternative fuels for use in the cement industry, helping to decarbonise this industry and reduce the reliance on fossil fuels. The increased processing capacity
has been achieved by installing new distillation columns to separate liquids, and 17 tanks to store or transfer the solvents. Transport is handled through two new high throughput tanker loading bays which manage logistics for processing and loading the recycled solvents ready for customer delivery. Nicola Henshaw, managing director
Hazardous Waste at Veolia UK said: “This latest expansion of our solvent treatment capabilities demonstrates our commitment to deliver high quality recycled products derived from advanced waste treatment. By preserving resources, reducing reliance on virgin materials, and delivering sustainable products to support manufacturers, we can also create major carbon savings.”
