Schools Eco-Innovation Awards Sponsorship

We are the proud sponsors of the Schools Eco-Innovation Awards scheme which is supported by Kevin McCloud. It was launched in September 2015 at The Moat School in London, a school for children with specific learning difficulties such as dyslexia and dyspraxia. This scheme will help to identify and nurture the extraordinary talents and creativity which these children often possess. We are looking for innovative design solutions to problems which the students have pinpointed. They should also consider how the designs have a positive effect on the environment.

"The Schools Eco-Innovation Award is great.  Its focus is on promoting a new way of thinking about our environment and ways to harness and protect its valuable resources.  There is no better way of addressing this than by tapping into the unique minds and creativity of students.” 

Kevin McCloud, MBE.


Identifying Japanese knotweed

Japanese knotweed identifcation is easy when you know what features to look for. During the summer months the plant has lush green leaves that are usually flat and often shovel or heart shaped in appearance. It grows from its rhizome system in the ground from early spring with new shoots appearing as early as March. These quickly develop into tall stems or canes which look similar to bamboo. In the UK it spreads from the crown and underground rhizome system rather than through seeds. During the summer months the weed can grow up to a metre a month, then as the autumn approaches the plant produces beautiful white flowers. Find out more about Japanese knotweed.

Why removing Japanese knotweed is so important

Japanese knotweed or Fallopia Japonica is a non-native invasive plant which grows without any problems below concrete and tarmac, causing severe damage to property, buildings, roads, driveways and drains. The plant causes serious issues for developers, professional advisors, contractors, home owners and landlords. Mortgage lenders often refuse to lend where their surveyor identifies the presence of Japanese knotweed on the property and sometimes where knotweed is present on adjoining land. This is due to the risk involved as the plant can cause significant damage and devalue a property. With a management plan in place, secured with an insurance backed guarantee, banks will lend.

Laws surrounding Japanese knotweed removal

Japanese knotweed and the soil it infests is classified as a controlled waste if it is being taken off the site so it is subject to all waste legislation under the Environmental Protection Act 1990. It is a criminal offence to consign or dispose of Japanese knotweed in a way that contravenes these regulations so all contaminated material must be removed by a waste carrier registered by the Environment Agency to a registered landfill site. Under the ‘duty of care’ it is the responsibility of the person consigning the waste to accurately classify the waste, clearly state it contains Japanese knotweed and ensure it is taken away by a registered waste carrier. Waste transfer notes must be obtained to provide an audit trail between consignor, waste carrier and landfill site. The Wildlife and Countryside Act 1981 makes it a criminal offence to plant or otherwise cause Japanese knotweed to grow in the wild. A more widespread legal tool is civil action under private nuisance where claims can be brought against a landowner who allows knotweed to spread into adjoining land. We call this Japanese knotweed encroachment.
