Recycling is the process of transforming items that have served their original purpose but are still durable into something that can be used for another purpose. There are two main types of recycling: internal recycling uses waste from manufacturing processes, like using spent grain mash from distilling in cattle feed. External recycling reclaims materials from worn out products. Recycling provides many advantages such as decreasing pollution, conserving resources, enhancing creativity, and making people more environmentally aware. Common materials recycled include paper, plastic, glass, fabric, yarn, and tin cans which can be made into items like woven baskets, planters, storage containers, quilts, and metal art.
