Footwear specialist Okabashi has been introducing a series of environmental measures designed to conserve energy and resources at its factory in Georgia.

To date, about 15% of the materials used to make Okabashi shoes are recycled, but the company says it is looking for ways to increase this proportion.

The company also pointed out that its products are vegan-friendly, while surplus products are often donated to charities such as the National Odd Shoe Exchange.

Thousands of shoes were given to the US military earlier this year, and Okabashi strives to ensure that much of its packaging is biodegradable or recyclable.

The company's employees have started an in-house recycling scheme for paper and plastic, and they are encouraged to take part in car-sharing or telecommuting when possible.

"For more than 25 years, we have been committed to keeping our manufacturing located in the United States, despite the challenges," said Bahman Irvani, president and CEO of Okabashi Brands.

"We now want to bring that same commitment to making smart decisions and upholding the highest environmental standards when it comes to how we make and distribute our materials and shoes."
