Reducing and Reusing Basics

The most effective way to reduce waste is not to make it first. Many materials and energy are needed to make new products - raw materials must be extracted from the ground, and the products have to be manufactured and shipped somewhere for sale. Therefore, reduction and recycling are the most effective way to conserve natural resources, protect the environment and save money.

Purchase second hand goods. You can find everything from clothing to building materials at professional recycling centers and consignment stores. Usually, secondhand goods are cheap and as good as new.

Please find products that use less packaging. When manufacturers use less packaging to manufacture products, they use fewer raw materials. This reduces waste and cost. These additional savings can be passed on to consumers. For example, bulk purchases can reduce packaging and reduce costs

Purchase reusable disposable items. Look for reusable items; small ones can be summed. For example, you can carry your own silverware and cups instead of disposable items.

Maintain and repair products such as clothing, tires, home appliances, etc. so that they do not need to be discarded or replaced

People's garbage is the wealth of others. Do not throw away unnecessary instruments, tools, clothing. Please sell or donate. You will help not only reduce waste but also others. Local churches, community centers, clothing stores, schools, and non-profit organizations can receive a variety of donations, including old books, work electrical appliances, unnecessary furniture.

Basic Principles: Principles of 3R reduction (reduction, reuse, recycling) and waste reduction principle. The goal of reduction is to achieve fixed production and consumption targets during agricultural product life cycle, reduce the introduction of different or unrepairable resources and materials, and waste production. Reuse refers to a resource or product that is first used multiple times. For example, livestock and poultry wash water can be used for irrigation not only to achieve the effect of sprinkling and fertilizing, but also to avoid draining sewage that contaminates the water environment. Recycling is a product after its function is fully available, it is not garbage. The first principle of waste reduction requires the avoidance of waste in production as a priority for economic activity.

The theme of 2017 is "Why wastewater?" This is about wastewater reduction and reuse. Theme is a word game. Because it concerns both waste of water and problems surrounding wastewater, both handling and reuse. Drainage is a valuable resource to help achieve Sustainable Development Goal 6. One aspect of goal 6.3 is to halve the percentage of raw wastewater and to increase global water recycling and safe reuse. After proper treatment, wastewater can be used for various purposes. For example, in the industry, water can be reused in cooling towers, and in agriculture water can be reused for irrigation.

Reusing things is one of the first important optimizations you learned when you started developing on mobile devices. In ListView or RecyclerView, you can maintain smooth scrolling performance with reuse. However, you can also reduce the final size of the APK by reusing it. For example, Android offers several utilities to change the color of assets by using the new L android: tint and android: tintMode for Android L, or using the old ColorFilter for all versions . Image: PNG or JPEG. Use PNG; because it is a reversible format, compression does not cause visual artifacts, making it ideal for textures and artwork. If there is space limit, please use JPEG or a combination of PNG and JPEG. High quality JPEG images are ideal for large realistic images like pictures optimized for JPEG compression.
