A Kenyan company is collecting plastic strewn across beaches and turning it into cold storage units. The recycled plastic is used to manufacture solar-powered freezers.

Kuza Freezers has been running for three years and has delivered more than 350 machines to customers, including fish traders, poultry and milk vendors and ice salespeople.

Each freezer comes with a battery that can be charged using a solar panel.

A two-hour charge means up to 7 hours of operating time
