The composition of paper Paper is made from wood pulp, which is obtained by breaking down trees into fibres. The fibres are then mixed with water and other additives, such as chemicals, to create a pulp. This pulp is spread onto a screen and pressed to remove excess water, resulting in a thin sheet of paper. The main component of paper is cellulose, which gives it strength and flexibility. The process of paper recycling Collection: The first step in paper recycling is collecting used paper. This can be done through recycling bins at schools, offices and recycling centres. It’s important to separate different types of paper, such as newspaper, cardboard and office paper, to ensure efficient recycling. Eco-warriors recycle for a brighter future! Remember, reduce, reuse and recycle paper to create…

Here are a few examples: Packaging industry: Recycled plastics are commonly used in the production of food containers, bottles and packaging materials. By using recycled plastics, we reduce the need for new plastics production and help conserve resources. Textile Industry: The fashion industry has embraced recycled plastics, using it to create fabrics for clothing and accessories. These fabrics are often known as “eco-friendly” or “sustainable” textiles, as they reduce the reliance on petroleum-based materials. Construction Industry: Recycled plastics can be transformed into materials used in construction, such as plastic lumber, insulation and even bricks. These materials are durable, lightweight and resistant to rot, making them an excellent alternative to traditional building materials. Automotive Industry: Recycled plastics is also finding its way into the automotive industry. It is used to manufacture car…

But, did you know that these adorable creatures are facing a huge problem? It’s called litter, and it’s something that we humans leave behind in the parks, like plastic bags, candy wrappers and bottles. When we don't clean up after ourselves, it can really harm these small animals and the places they call home. Mice, for example, might get tangled up in pieces of trash, making it hard for them to move around and find food. Snails could mistake small bits of plastic for their favourite snacks, but eating litter can make them very sick. And for cute rabbits, lizards and frogs, litter can be like a dangerous obstacle course that they have to navigate every day. But wait, here’s the good news! We can all be superheroes for these…
