The circular economy and Malta
Our globalised economy has generated wealth and prosperity for millions of people around the world. Living standards have been raised to unprecedented levels. But this comes at a cost. The environment has suffered greatly, not only in terms of constant extraction of natural resources, but also at the hands of polluting processes and end-of-pipe waste.
Recognising that economies, and indeed our planet, have finite resources, the circular economy has become a popular concept among policymakers and stakeholders in recent years. The current linear ‘take, make, use, and throw away’ model of production entails substantial value losses and negative effects along the material chain. Because of this, we should ideally be designing and manufacturing products for continuous reuse and recycling, maximising resource efficiency, and minimising leakages and waste.
The appeal of the circular economy lies in its various environmental and economic benefits. Using secondhand materials and waste within business could cut costs, while their sale adds a potential revenue stream. The circular economy also offers new and vast business opportunities in areas such as product eco-design and product/material regeneration, all of which help create high-skilled jobs and investment in new technology.
The idea of the circular economy is particularly relevant to Malta, given its geographical circumstances, high import dependency, and lack of natural resources. Embracing the principles embodied within the circular economy concept would have an immediate positive impact on the environment while benefitting Malta’s long-term economic prospects.
However, we are still at the doorstep of circularity. Malta’s natural resource productivity fell by 7.6% between 2000 and 2015, with increased domestic material consumption outpacing economic growth. Waste management in key sectors like construction remains a major issue.
To encourage the shift from concept to the creation of circular economy business models, the University of Malta is part of the R2Pi Horizon 2020 project. Among other goals, it hopes to identify both market and policy failures that hinder the uptake of such models by business entities across Europe.

In search of perfect silicon
Silicon is the go-to material for solar devices like photovoltaic panels despite its relatively low energy conversion rate of 15-22%. Researchers all over the world are analysing materials and creating new ones to find a better solution. A lucky handful are armed with a laser scattering tomograph (LST), the best instrument for the task.
An LST illuminates the sample material with an infrared laser beam, which scatters wherever it finds a defect. If there is a defect in a material’s structure, even one just a few nanometers wide, the very sensitive CCD camera at the other end of the machine will pick it up, allowing researchers to learn and adapt. It also boasts a robotic system that allows it to automatically load multiple samples at once.
The LST is very rare, but fortunately, one has found a home at the University of Malta’s (UM) Institute for Sustainable Energy (ISE), a brand new, state-of-the-art facility aimed towards finding efficient solutions for harnessing solar power to its fullest extent. ‘There are probably 10 to 12 of these worldwide,’ confirms Prof. Luciano Mule’ Stagno, Director of the Lab at the ISE. ‘Ours is one of the few in the world to be found in a university, almost certainly the only one in a university in Europe. Most of these machines are in industry settings,’ he says.
This enables the UM to conduct cutting-edge research in a field that is practically nascent, putting it at the forefront. With the LST, material engineers could unlock the secrets behind the perfect variation of defect-reduced silicon. This rise in efficiency could have a substantial impact on the worldwide sustainable energy market.

Igniting a sun on Earth
The Sun is the most important source of energy for life on Earth. Powerful as it is, what would happen if humankind could create a miniature sun in a lab and harness its energy? This is the mission of Dr Ing. Nicholas Sammut, Dr Ing. Andrew Sammut, and Karl Buhagiar.
Extreme heat for gears
Cars, motorcycles, machinery—gears are at the heart of them all. Dr Ing. Ann Zammit writes about challenges in producing and improving gears to make everything safer.

Think Critically, Think Malta
Let us strengthen Malta’s democratic system by thinking critically. We need to learn how to avoid blindly accepting or rejecting ideas and opinion based on our political affiliations or unquestioned, long-held beliefs. Let us actively go against the dualistic thinking that dominates local public debate. Let us, for example, phase out media outlets financed by political parties; amend the constitution to facilitate the entry of a third political party to parliament; and put critical thinking at the centre of our educational system by strengthening subjects that enhance it (literary and rhetorical analysis, logic, philosophy and the scientific method).

The Diploma in Design Foundations Exhibition highlights the yearlong visual and creative process of 80 students. It is a study in representation, composition, and perception of space. Pencil drawings, typographic prints, cast sculpture houses, and panoramic landscape photography fill the studio space.Continue reading
What can Malta learn from Singapore?
By Dr Andre Xuereb and Dr Edward Duca
Singapore is Asia’s success story. It has a landmass just over twice that of Malta but produces over 30 times its economic output. Singapore has invested heavily in quantum technologies, turning itself into one of the world’s leading industrial economies. Though poor in natural resources, Singapore’s investment in knowledge has resulted in it becoming one of the world’s healthiest industrial economies.Continue reading
Fly power for neurodegeneration
By Rebecca Borg
Spinal Muscular Atrophy (SMA) is a neurodegenerative disease that causes motor neurons to deteriorate. These nerves are required for voluntary muscle activity control. Neuronal loss leads to progressive muscle weakness that makes it difficult for one to move and function normally. These devastating consequences make SMA the leading genetic killer of infants, who succumb to the effects of the condition within a few years.Continue reading
Nicotine stresses you out!
By Caitlin Davies
Every day in Malta, one person will die from a smoking-related illness. People usually begin smoking tobacco in their adolescence and addiction quickly follows. Quitting is hard and the majority are unsuccessful. Nicotine, with its crippling withdrawal symptoms, is to blame. Research suggests this component of tobacco can be more addictive than heroin. Smokers say that nicotine is pleasurable and enables them to concentrate and reduce their anxiety. Scientists think the opposite.Continue reading
