Looking for ideas, tricks or statements that demonstrate I am an environmentally friendly magician.
(I am quoting for a close-up gig at a very environmentally conscious company)

I perform passing the weights as taught by Ed Parrish in Pop Haydn’s tutorial available from his website. When I started performing it the only set available was made from aluminum and available from Ronjo Magic. So to justify the props my story was that this is a trick that was performed a couple of hundred years ago for royalty using gold ingots. I don’t have gold ingots but I got these aluminum ingots really cheap off eBay. I understand that 3-4 aluminum cans melted down will give you one of these (as I show one of the weights). You could adapt that sort of presentation to mention recycling.

The theme of sustainability can possibly be incorporated into any torn/cut and restored effect ie with a card, napkin, rope. The props apparently get restored and reused.

Eco edition Bicycle Playing Cards are made from recycled materials.

What kind of things do you already do? Scripting is what you are looking for and without knowing what types of things you do, helping with what to say is impossible.

Here are a few plots off the top of my head:

Vanish a sponge hamburger and produce 2 sponge carrots, etc.

Torn and recycled newspaper.

Your invisible deck that saves trees.

Multum in Parvo and how you now use less milk. In fact you use almond milk, and less of that!

And Wrayvn makes a great point. What do you do now?

Why not develop presentations that speak to it.

You could restore and refill a soda can. Lots of versions on youtube. Tedious to set up though.

In my parlour show, I combine 3 tricks to go from newspaper to liquid to silk to paper money. (Point: Recycling saves money).

The first question is Are you and environmental friendly person? And can you provide facts that show that. Eg planting trees, cleaning beaches, recycling club.
Have some of your props made of recycling material or are made of material that will degrade eg wood,
Also the show is about magic, not about sustainability, so any statement you made has to be subtle and not the center of your show otherwise it will sound fake and will take away for the entertainment
My 2 cents

Look at the company's mission, products, and clients. Are they focused on recycling? Reducing carbon emissions? Have they won any awards or been noted in the news?

From there, incorporate the important points into scripts...you can script anything.

The Professor's Nightmare becomes a story about the Company balancing environement, cost, and quality, and they're able to make them all equal.

Ring and Rope is a story about how ring is a symbol of commitment, and the company is committed to the environment.

Mark Mason's No Tear T&R Newspaper can be about all the stories about the company's environmental success...how they all come together.

Companies love when you focus on thier work/clients/issues.
