Walgreens plans to build what it believes will be the nation’s first net zero energy retail store, producing energy equal to or greater than it consumes.
Walgreens plans to achieve that by utilizing solar panels, wind turbines, geothermal technology, energy-efficient building materials, LED lighting and ultra-high-efficiency refrigeration.
Sewage sludge that has gone through the THP process before being anaer turkey phone number obically digested yields significantly more biogas with which to generate electricity to help run Thames Water’s treatment works. By using anaerobic digestion alone, about percent of the organic material in sludge turns into biogas. Thermal hydrolysis increases this to between and percent, says Lawrence Gosden, Thames Water’s director of capital delivery.
By installing THP at six of its main UK sewage works, along with other renewable energy activities including solar power, Thames hopes to meet its goal of generating percent of its electricity demand from renewable sources by .
Thames Water will install the new THP plants at four London locations — Beckton and Riverside sewage works in Essex, Crossness in Thamesmead and Longreach in Barking — along with Oxford and Crawley sewage works by .
Four of these plants will benefit from a sewage version of a cider press, which will squeeze out percent more water from the sludge before it goes through the thermal hydrolysis and anaerobic digestion processes.
Using THP also means there is less solid matter left over at the end, which will halve the number of trucks needed to take it from the sewage works to farmland where it is used as fertilizer recycling the organic material back into the soil. This will save the company around £ million million every year.
Generating its own power from sewage and also solar panels has helped Thames Water reduce its carbon emissions by percent on levels.
