These devices are thoroughly checked and are sold with a two-year warranty, just like new mobile phones. Since September 2021, the Proximus shops and online shop offer customers refurbished smartphones as an alternative to new devices. Mobile phones that can no longer be used are recycled by partners Umicore, Recupel, Out of use and Brainscape. Refurbished smartphones are put up for sale. For its mobile devices, Proximus collects old mobile phones in order to have them refurbished or recycled. Proximus focuses on further developing its circular business models, both for fixed and mobile devices.

In this context, the report mentions the initiatives Proximus is taking to become a truly circular company by 2030.

Whilst the GSMA's vision lays out a future pathway towards true circularity, progress is already being made by mobile operators. Manufacturing and assembly also contribute to greenhouse gas emissions from fossil fuel use. Mining for these materials can cause negative environmental and social impacts. Over 50 different materials can currently be found in an average smartphone, including plastics, ceramics, rare metals, copper and silicon. If you have an Android then Anki is a no brainer since the Android app is free - but even 25$ is nothing compared to 80$ for Brainscape.Regarding the life cycle of a mobile phone, the bulk of the environmental impact - around 80% - lies in its manufacture. Flashcards are best done if you make your own and Anki allows you to input latex and pinyin for Chinese. Given these, I think Anki is far, far away the better value. Pros: adaptive Spaced Repetition system which ensures you don't throw something into easy too fast, you can install multiple tools for things like Latex and eastern languages, free desktop app with 25$ iphone app, you can edit cards off iPhone app, shortcuts galore for navigating the app quicklyĬons: design looks outdated, you can't study multiple decks at once, not as many classes Also, some of the classes, even brainscape certified ones, can be pretty low quality Pros: Lots of classes, 5-choice SR confidence system which makes it simple, modern interface, you can study multiple decks at onceĬons: 80$ for lifetime membership, can't edit the cards on mobile app, images can get truncated if too wide. Currently I'm studying Chinese and financial mathematics. I'm glad I did that instead of the lifetime membership because it turns out Anki is much, much better.

When I was studying for my certificate test last month I started off with Brainscape and even paid for the premium membership for 1 month.
