Few 27-year-olds look at used cooking oil and see a green business opportunity to produce soap or dog food.But that is what Hugo Daniel Chávez, a project manager for the NGO Sustenta Honduras, has done.

"We have so many businesses and domestic practices that create waste, so we are trying to transform waste and give it a second life," he tells the BBC.Across Latin America, several million tonnes of cooking oil are consumed every year. It is often used to fry food, mostly chicken, plantain strips, chips and pork.But reusing and heating it too often - as is often the case in Honduras, where there is a huge black market for used cooking oil - can create compounds which are bad for consumers' health.

Improperly discarded, it can also have a massive detrimental impact on the environment.If it is drained down the sink, it can damage pipes and contaminate groundwater, and when it is tossed by the side of the road, it can contaminate freshwater and crops many communities rely on.

Faced with these health and environmental hazards, the young green entrepreneurs behind Sustenta tried to come up with a solution which would not only give businesses an incentive to dispose of their oil and grease properly, but also turn these waste products into something useful.

The NGO's executive director, Ricardo Pineda, explains that their idea originated from earlier efforts by different companies and organisations to transform used cooking oil into biodiesel. "But in Honduras, we don't have a market for biodiesel," he says."Our concert is called 'No more barriers, just great music', because NOYO is breaking down the barriers, so as musicians we can just focus on our love for the music," said Ms Spray.

"Our first piece of the concert, which is called Barriers, by Oliver Cross, has a really lovely horn solo which I enjoy playing.""What I love about NOYO is the diversity, and all musicians share the love of music and you can really hear that at our concerts," she said.

"NOYO is proving that with a few adjustments, ensembles can be inclusive."It's really important to me that the audience members can see themselves represented on the stage, and I love that about our relaxed performances."
