Did you know that about one-third of all food produced in the world is wasted every year? For kids, thinking about food waste might seem boring, but it's actually a really important and cool way to help our planet and save money.

Over 65% of global nickel production is used in the manufacturing of stainless steel, but the best source of nickel depends heavily on its intended final application. Nickel is primarily sourced from two distinct ore types—laterites and sulfides—each requiring different processing methods and yielding varying grades of metal. This guide explores the different sources to determine which is optimal for specific industrial uses.

Over 70% of the world's cobalt supply originates from the Democratic Republic of Congo (DRC), creating a highly concentrated and geopolitically sensitive market. This reality, coupled with cobalt’s indispensable properties in modern applications, forces the urgent question: is cobalt essential?

According to a 2024 study, global bioplastic production is predicted to increase significantly, positioning these innovative materials as viable alternatives to conventional plastics. This growing market has led many to wonder: Is gelatin used in plastic, specifically in the development of these sustainable biopolymers? The answer is yes, gelatin is a foundational material in certain types of biodegradable bioplastics.

According to Nespresso, their capsules contain 100% pure roast and ground coffee. The question, "Are Nespresso pods natural?" comes down to a deeper look at the raw materials, the production process, and the specific variety of pods you purchase.

The history of canning dates back to the late 18th century, with Napoleon Bonaparte offering a prize for a new preservation method to feed his army. While we call them 'tin cans,' this moniker is largely historical. Most modern food cans are made from steel with a very thin layer of tin to prevent corrosion and keep food safe for long-term storage.

Did you know that eggshells are approximately 95% calcium carbonate, a highly effective and inexpensive source of calcium? Many people discard eggshells without realizing what valuable minerals they contain for both human health and gardening, making it crucial to know what are eggshells rich in before you throw them away.

In 2023, Singapore generated 755,000 tonnes of food waste, with a recycling rate of only 18%. This persistent issue prompts many to ask: why is food waste still a problem in Singapore despite increasing public awareness and government initiatives?

The global demand for critical minerals is projected to double by 2040, driven largely by the shift towards clean energy technologies. These vital materials, which include lithium and cobalt, are the foundational components for a vast array of modern products, from smartphones to electric vehicles. But what exactly comprises the official critical minerals list, and why is securing their supply so crucial for the future?

The Earth's chemical composition is essentially fixed, meaning all matter must be reused. This perpetual movement and regeneration is why we call nutrient cycles cycles, describing a system of continuous recycling between the planet's living and non-living components.
