DirtBags have launched on Kickstarter - https://www.kickstarter.com/projects/forthetrail/dirtbags-reusable-compostable-zip-bags-for-adventures

A project by @ForTheTrail

Your support would mean the world!!!

Do you use single-use energy gels, powder sachets or plastic ziploc bags for your adventures, races, big days out in the mountains and ultra-marathons?

DirtBags are the first, ultralight, reusable and home-compostable zip bags designed to organise and carry your fuel and essential items for long days out on the trail.

I have been working on prototypes to replace single-use energy gels and plastic ziploc bags whilst still giving you the convenience of portion control with gels/powders and the option to carry small essentials, mandatory gear and spare kit in the larger DirtBags.

You use them on an adventure, wash them and then reuse, again and again.

DirtBags have been created to stop a linear waste model, especially when single use plastics are used in sports and hobbies based on nature, this doesn't make sense.

Instead, we should be focusing on circular life cycles and a reduction in the demands on the planet.

So, someone suggested #Graywater / #Greywater as a topic for #SolarPunkSunday . I managed to find this article which has a lot of information!

How To Build A #DIY #GreywaterSystem (Complete Guide)

January 9, 2022 by Dylan Crosbie

"Welcome to our complete guide to building your #DIYGreywater system!

"A greywater system will decrease your carbon footprint, save water and decrease your utility bills. The system recycles water from your home and allows you to use it again for irrigation and flushing toilets.

"It can be a simple, low-tech system that will be cost-effective in the long run and lower your water usage by up to 40%.

"The best part? You can build it yourself!

"The following article will outline what you’ll need to build your greywater system. This guide has it all, from understanding how a greywater system works to breaking down the required materials!"
