GACW (Global Air Cylinder Wheels), with a valuation of $40 million, is raising funds on StartEngine. The company has reinvented the wheel by designing its patented Air Suspension Wheel. The wheel of GACW is an airless mechanical one made of steel with in-wheel pneumatic suspension. GACW’s green technology provides a cost-effective and eco-friendly alternative to pollutive rubber tires. The testing of GACW’s wheel solution has been tested by global miners, and additional Beta tests are to commence at mines sites in 2022. Dr. Zoltan Kemeny founded GACW in November 2019. The current crowdfunding campaign has a minimum target of $9,999.36 and a maximum target of $1,643,826.24. The campaign proceeds will be used for the installation of the ASWs in Chile and Australia.

Analyst Report Analyst Report Methodology Article

A recent study estimates that rubber tires account for as much as 10% of all microplastic waste in the world’s oceans. Another study says 28%.

Rubber tires need to go. And the sooner the better. Governments are beginning to impose requirements on how rubber tires are disposed of. 

While a step in the right direction, it’s not nearly good enough. 

The only real long-term solution is getting rid of rubber tires altogether. And the first industry that has the most to gain from switching to non-rubber tires is mining. 

Thanks to one innovative startup — Global Air Cylinder Wheels (GACW)it’s happening right now.
