     The traditional tent cities at festivals such as Glastonbury may never be the same again.In a victory of

green business that is certain to appeal to environmentallyaware musiclovers, a design student is to receive financial support to produce ecofriendly tents made of cardboard that can be recycled after the bands and the crowds have gone home.

      Major festivals such as Glastonbury throw away some 10,000 abandoned tents at the end of events

each year.For his final year project at the University of the West of England, James Dunlop came up with

a material that can be recycled.And to cope with the British summer, the cardboard has been made

waterproof.

      Taking inspiration from a Japanese architect, who has used cardboard to make big buildings

including churches, Mr.Dunlop used cardboard material for his tents, which he called Myhabs.

     The design won an award at the annual New Designers Exhibition after Mr.Dunlop graduated from

his product design degree and he decided to try to turn it into a business.

     To raise money for the idea, he toured the city's private companies which fund new business and

found a supporter in the finance group Mint.He introduced his idea to four of Mint's directors and won

their support.Mint has committed around £500,000 to Myhabs and taken a share of 30 percent in

Mr.Dunlop's business.The first Myhabs should be tested at festivals this summer, before being marketed

fully next year.

     Mr.Dunlop said that the design, which accommodates two people, could have other uses, such as for

disaster relief and housing for the London Olympics.

     For music events, the cardboard houses will be ordered online and put up at the sites by the Myhabs

team before the festivalgoers arrive and removed by the company afterwards.They can be personalized

and the company will offer reductions on the expense if people agree to sell exterior (外部的) advertising

space.

     The biggest festivals attract tens of thousands of participants, with Glastonbury having some 150,000

each year.Altogether there are around 100 annual music festivals where people camp in the UK.The

events are becoming increasingly environmentally conscious.
