    Householders in Midlands in trial to remedy nation's draughty unblocked chimneys

    Across England there are 9 million fireplaces which are not permanently blocked. Often equivalent to keeping a window open at all times, an unblocked chimney can add significant cost to the typical heating bill as warm air escapes up through the chimney and into the atmosphere.

    Biffa's switch to rail transport of inert waste greatly reduces carbon emissions

    Biffa saves 6,600 tonnes of CO2 emissions transporting material by rail

    Waste firm Biffa reveals it has saved 6,600 tonnes of CO2 emissions by switching to the usage of rail links for the transportation of mostly inert waste material to its facilities. This follows the Group's strategic rail partnership with GB Railfreight to increase its capacity for transportation via rail, thereby reducing its reliance on road haulage. Since last year, the Group has transported over 600,000 tonnes of inert waste by rail.

ABERDEEN INTERNATIONAL BUSINESS PARK GETS SUSTAINABLE SUDS TREATMENT WITH HYDRO'S POLLUTION CONTROL TECHNOLOGY

Aberdeen's new International Business Park, built next to the City's International Airport, is delivering a best-practice Sustainable Drainage (SuDS) scheme using filtration and bioretention technologies from Hydro International to meet strict planning and pollutant removal criteria.

marketplace hydro webA wide-variety of SuDS components have been included for the 31,000 m2 first phase of the development to meet the level of treatment required by the Scottish Environmental Protection Agency (SEPA) to help protect the water quality of the River Dee, a well-known salmon river.

To meet stringent planning requirements, consultants Mott MacDonald selected Hydro International's unique Up-Flo™ filtration units and Hydro BioCell™ biofiltration units for key parts of the site.

"SEPA required two levels of pollution control in the drainage treatment train for some areas of the site," explains project engineer Nick Watson of Mott MacDonald.

"The six Hydro BioCell™ units are installed in a landscaped courtyard garden around three linked four-storey commercial blocks. There is also a two-storey 1,197 space car park and runoff from its draining surface is treated via four Up-Flo™ Filters in concrete manholes.

"Space constraints meant that finding small footprint solutions that could achieve high treatment levels was limited. There are some occasions where the more natural engineering approach is less suitable due to a lack of space and having an option like Up-Flo™ can be useful," continues Nick Watson.
