Rob Cole, Sheffield Sustainable Kitchens and Al Daw, Sidney and Matilda

Here's a sustainable, ethical business, thriving and continuing to grow a decade after launching. It has environmental and social responsibility at its core and its leader shows how businesses can be agents for positive change.

Here also is your invitation to an amazing party in a brand new gallery space in Sheffield where you can enjoy exceptional art with "an alternative take on the season of goodwill" – and a free drink.

Yes, it's another double-header radio show for you. I was joined in the studio on Friday 14 December by Al Daw and Rob Cole for my weekly Business Live programme on Sheffield Live. The podcast is here.

Rob runs Sheffield Sustainable Kitchens which he launched nearly 11 years ago.  Now the praise and accolades are unstoppable – two weeks ago SSK was named winner of the Excellence in Corporate, Social and Environmental Responsibility Award at the Sheffield Business Awards.

The company was founded on the basis of environmental and social responsibility, says Rob. Its beautiful kitchens are built from reclaimed and recycled timber and other woods. They are stunning (check out the gallery on their website).

In the interview Rob talks us through how and why he launched the business, its environmental and social impacts, an initial period of growth up to five employees, the recent spurt of growth to 15 staff and the challenges on the way.

"I'm still learning now," he says, "When I started I knew what I was doing about how to fit and design a kitchen – I've learned a lot since then about how to run and lead a business."

Businesses can and must be agents for change and for mitigating our environmental impact, says Rob. Governments are failing to lead or to really encourage the change. "We need a serious push if we are to avert climatic disasters," Rob adds, and so "the business community needs to drive forward positive changes."

That lead us on to a conversation about corporate social responsibility and greenwash. But Rob explained why he's hopeful for the future.

Finally Rob reveals the decision he made relatively early on (but which he wished he'd made earlier) and how that led to a drastic increase in customers.

Also on the programme: Al Daw who has taken on a new space which he is developing into a gallery, creative project space and arts club.

The space is Sidney And Matilda. What's it all about, and what's the vision for this exciting new gallery and space? Al spills the beans.

We cover collecting art and supporting grass-routes artists; cynicism in the corporate art world; collaboration between artists and more.
