What if things we throw away could be put right in a block maker, and turned into bricks? That’s beginning to happen in multiple ways! From plastic bricks made of recycle waste to machines that crush boulders and rocks into liquid cement, and make bricks, there are great things on the horizon!
These blocks can be made in the same size as standard concrete blocks, though don’t have the same weight-bearing capabilities. The blocks do have good acoustic and thermal insulation properties, which ByFusion says makes them ideal for use in road projects or fill-in building frames.
Yusef Waghid ~ Our Universities Must Be Centers Of Open Debate For Africa To Make Political Progress
To understand what an African philosophy of education is and why it’s so important, consider the role that universities should play in any society.
Universities, no matter where they are, ought to be places where knowledge is internalized, questioned and considered. Such knowledge should respond to a university’s particular social, political and economic context. The pursuit of such knowledge happens in a quest for human development. What would a university be if its only purpose was to produce knowledge without considering its effects on a society and its people?
But it’s perhaps precisely this disjuncture—between what universities purport to do and what happens in society—that starts to explain why knowledge in Africa has become so misplaced. This has happened in several Arab and Muslim states, where some universities have seemingly become reluctant to encourage critical learning. Knowledge produced in such universities does not attend to public concerns, whether these are political, economic, social or cultural.

Over the past few years, these deceptively simple questions have been beset with controversy. Librarians at some of the world’s wealthiest institutions have announced that they can no longer afford to purchase the materials their researchers need. Leading academics have organised boycotts, petitions and mass resignations to protest the combination of prohibitively high prices and profit margins that rival those of the big oil, pharmaceutical and technology firms. A recent paper found that just five multinational publishing conglomerates accounted for 50% of all papers published in 2013.
It may seem like an administrative afterthought, but the issue of how research is communicated in society raises questions that cut to the heart of what academics do, and what academia is about. The scale of the entanglement between academic research and big publishers may well lead us to ask: who is serving whom? Does our scholarly communication system put the needs of researchers first? Or does it prioritise the uninterrupted profitability of a handful of publishers?
