I have to agree with you on the fact that the Dragons are in it solely for the money and this being a classic case of ‘greenwashing’

‘I dont care about carbon footprints, money is money, I know that sounds bad, but if a product costs me £5.99 ill pay that not £8.99 for a friendly one’

In fairness to Duncan, I think he saw what the other Dragons saw in the company (before they’d heard the people story), that it wasn’t going to be big enough for their investment – and high return requirement. Duncan was making the point that someone who’s “on a crusade” to save the planet might not be focused on the business side, which is why I think he declared himself out. I think he, along with all the dragons warmed to the pair when they’d heard their story.

With what had already been said in the segment about packaging companies having a recycled packaging arm, and what Theo said as they were agreeing the investment, I’m sure they’re not going to be exclusively a recycled packaging company for long (their tinyboxcompany website might sell exclusively recycled products, but as a company I’m sure the Dragons are making them diversify).

I might be viewing this a little cynically, but the Dragons are in it for the investment first, not the planet.
