Why Anaerobic Digestion Is Environmentally Friendly

E-mail Print PDF

The constant battle to reduce greenhouse gases has resulted in a constant search for more environmentally focused waste disposal systems – from an influx of recycled materials being crafted into other useful objects, through to sourcing eco-friendly treatment systems for our waste water – finding new ways to protect the environment is high on everybody's radar.

The Effect Of Anaerobic Digestion

It is this constantly reaching for better solutions that has driven Anaerobic digestion to where it is now. By combining biodegradable materials, we now have an additional process for creating electricity and organic compost. This means fewer fossil fuels will be burned to heat our homes, chemical fertilisers won't be in such high demand and our food will have a milder treatment system in place.

Wind energy has become low cost option in United States

Renewable energy sources such as solar and wind are declining in prices. This especially refers to latter as according to the US Department of Energy report wind energy prices have gone below 2.5c/kWh in 2014, which is a 65.5% decline compared to 2009.

There are many utilities which are now selecting wind as one of the cheapest renewable energy options, particularly in the central United States. This means that wind energy is now cost-competitive and economically viable option that can compete with coal and natural gas in many U.S. states.

The strong growth of wind energy sector in United States does not only mean more clean renewable energy and less fossil fuels burned, it also means plenty jobs for U.S. economy. It has been estimated that U.S. wind energy industry currently employs more than 73,000 people.


Global renewable energy growth continues

Global renewable energy capacity continues to grow year after year. In 2014, around 135 GW of new renewable energy capacity were added worldwide, meaning that the total global renewable energy capacity now stands at around 1,712 GW, representing 8.5% increase from the year 2013.

In the same time, carbon dioxide emissions remained pretty much the same in 2014, as compared to 2013, even despite the 1.5% annual increase in global energy consumption.

The growth in renewable energy capacity is the main factor preventing the growth in carbon emissions. The other important factor is the improvement in energy efficiency.


Hydroelectricity gets an ecological makeover in Norvay

Norway, a country that generates more than 80% of its electricity from hydropower, has added to its renewable repertoire in the guise of a beautifully Kebony-clad 30GWh plant. The plant is situated deep within the mountains of Helgeland, a hiker’s paradise just below the Arctic Circle. The region is known for its unique coastline and spectacular mountain formations and the architects wanted the plant’s design to be inspired by and reflect the landscape, whilst also functioning as an attraction for hikers in the back country wilderness.

The Øvre Forsland power station has been designed to educate hikers about power production by allowing visitors to experience the production of hydraulic electricity at various points throughout the process. From the nearby bridge, the powerful water flow that drives the turbines can be seen emerging from the station and the heart of the plant and the inner workings are exposed through an opening, which reveals the light design of the interior - inspired by the mystery of the Northern Lights.

Øvre Forsland is located on the river bank, in a clearing at the edge of a spruce forest. A main inspiration for the design was the verticality and the irregularity of the spruce trees. Along with extensive use of stone, slate and glass on the exterior of the building, Kebony wood is used in the building’s cladding. Kebony was chosen for the build primarily to its beauty and to its hardwearing qualities but sustainability was also of paramount importance to the architects. Kebony is a Norwegian wood, produced using sustainably sourced soft wood species which are impregnated with a non-chemical bio-based product and heated under pressure, resulting in a highly durable and maintenance free product. As such Kebony diverts demand away from our endangered tropical forests.


Stay above the smog – try these business tips

We are living in smog – crop yields suffer in India because of nuclear power plants, the Hollywood sign is barely visible through car fumes, Chinese fashion shows feature the latest in gas mask chic, and fracking sites have become a major concern in the UK.

This is just the tip of a rapidly melting iceberg – and the situation is getting worse.

Political and environmental activist Naomi Klein has claimed that this disastrous impact on the world climate will continue so long as capitalism continues unfettered. Whencash is concerned, according to Klein, the dollar will ignore the environmental impact.

Yet, big business is also providing a light at the end of the carbon-filled tunnel.

Companies like Tesco, B&Q, DuPont and Asda have all made pledges to cut carbon – and their profits have increased as a direct result of their efforts.
