Concrete is one of the most widely used materials in the world, but it’s not invincible. Over time, cracks form due to environmental stress, requiring costly and resource-intensive maintenance. Enter bacteria—nature’s microscopic masons.
Dormant bacteria embedded in concrete mix awaken when cracks form and water seeps in. These bacteria then produce limestone, effectively healing the damage. This process not only strengthens the material but also reduces the need for repairs.
Plastic pollution is a global crisis, threatening marine ecosystems, wildlife, and human health. While technologies like The Ocean Cleanup’s Interceptor 006 demonstrate impressive progress in waste management, addressing the root causes of this issue requires systemic changes, from reducing plastic production and improving waste management to promoting circular economy policies and empowering individuals. Innovative solutions like the SeaBin Project, plastic-eating enzymes, and waste-to-energy initiatives complement these efforts, paving the way for a sustainable future.
The year 2024 presents a unique opportunity for the world’s wealthiest nations to lead the charge in addressing climate change and promoting sustainability.

E-waste, encompassing discarded electronics like smartphones and refrigerators, poses a complex disposal challenge due to hazardous materials. Rapid technological advancements lead to shorter product life cycles, resulting in exponential e-waste growth. Globally, 53.6 million metric tons of e-waste were generated in 2019, with an expected rise to 74.7 million by 2030.
