Waste, steam, district heating, and Nottingham

There are many towns and cities around the world that use district heating, and many of these district heating systems also use steam.

For an example of this in the UK we chose Nottingham, where domestic and commercial waste is used for both electricity and heat. Nottingham is a city in the county of Nottinghamshire in the East Midlands of England. The district heating network in Nottingham is the largest in the UK and has been providing heat and hot water for three decades.

The incinerator lines can generate to 52 tonnes per hour of steam at 23.5barg 371°C. The steam produced is piped 1.5kM from the facility to an energy generation and distribution facility on London Road in Nottingham which is operated by EnviroEnergy Ltd. It is then passed through a condensing extraction steam turbine to generate electricity and provide heat to the district heating network. The district heating distribution network comprises of 85km of insulated pipework carrying pressurised hot water around Nottingham City Centre.

Enactus – Best Kept Sustainability Secret in Global HE?

Last week I attended, for the first time, the Enactus National Finals in London and was totally struck by the sheer enthusiasm, innovation, sporting and supportive community that has been nurtured by the Enactus UK team and the participating universities.

35 universities groups of active Enactus teams from across the UK competed in showcasing their superb projects and it was hard to not be impressed by any of them. The five finalists (Queens University Belfast, Leeds, Southampton, Sheffield and Nottingham) were, perhaps, standouts in terms of the quality of the projects and the maturity of their thinking. Augmented by slick, well rehearsed and emotive presentations, those five certainly deserved their place on the final stage. Southampton were overall winners with Southampton in 2nd place with some brilliant projects.

I only learnt about Enactus less than a year ago when the president of the Nottingham branch contacted me to develop ideas of how The University of Nottingham might work more closely with them. Within a few minutes it was clear there were plenty of opportunities for us to work collaboratively on local projects and support their ideas for some spectacular overseas projects like Empower Malawi and Aquor.

I would encourage you to investigate further the great work underway across universities in the UK and overseas that are being carried out by highly motivated, smart students on a voluntary basis. They build their Enactus work around their courses of study and add so much value to their CVs they are sought after graduates at the end of it. The impressive panel of alumni who judged the UK National Finals is testimony to that.

Enactus thrives because it has autonomy, imagination and because it empowers students. Every single project they are working on improves the lives of the people they work with by tackling social, environmental and economic challenges. They are making a fantastic difference to the lives of communities all over the UK and globally. Branches across the globe will come together in October to compete in the World Cup and Southampton will be the UK’s representative.

This movement is an incredibly important part of the higher education sector’s contribution to sustainable development and should be recognised as such.
