Elaine and Ross hate recycling. Both know first hand about our computers’ and smartphones’ life. About the wasted opportunities to better use the precious resources into it. Elaine Brown is the CEO of the Edinburgh Remakery who refurbished 295 laptops last year. She’s also a keen expert on the right to repair issues. Ross Cockburn is the Trustee of Reusing IT who has been dealing with repaired devices from Africa to Ukraine over the last 25 years.
Gael Duez sat down with them to cover multiple topics such as: The business of ITAD; The financial and social rewardings of giving to charities; The SSD revolution for longevity; Linux, the (not so) secret weapon for reusing IT; The reality of Digital poverty; Right to repair laws without teeth; The multiple cost of Windows 10 EOL; And … a new acronym invented during the recording: IUTA!
