Case-Mate's new line of iPhone cases is designed for the user who loves the iPhone and the environment. The cases are made out of recycled PET bottles.

"As part of our greater effort to encourage more sustainable practices, we've introduced a line of fashionable, functional and environmentally responsible cases," said Shashi Reddy, Case-Mate CEO. "By creating Case-Mate products using recycled materials, we're helping millennials stay stylish and environmentally conscious."

The cases feature a translucent, slim design and are available in a variety of colors, including pink, black, turquoise and orange. The rPET case costs $30 and follows a minimalist design similar to Case-Mate's other iPhone accessories.

For additional phone protection, the company offers the Barely There. Made from hard shell polycarbonate, the protective case features impact resistance combined with lightweight design. It costs $25, and is available in eight different colors. Barely There fits all iPhone 4/4S devices and is designed to allow access to all ports and controls.
