Recycling is the process of converting waste materials into new materials and objects. This concept often includes the recovery of energy from waste materials. The recyclability of a material depends on its ability to reacquire the properties it had in its original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. It can also prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, reducing energy use, air pollution and water pollution.
Scrap consists of recyclable materials, usually metals, left over from product manufacturing and consumption, such as parts of vehicles, building supplies, and surplus materials. Unlike waste, scrap has monetary value, especially recovered metals, and non-metallic materials are also recovered for recycling. Once collected, the materials are sorted into types — typically metal scrap will be crushed, shredded, and sorted using mechanical processes.
Material efficiency is a description or metric ((Mp) (the ratio of material used to the supplied material)) which refers to decreasing the amount of a particular material needed to produce a specific product. Making a usable item out of thinner stock than a prior version increases the material efficiency of the manufacturing process. Material efficiency is associated with Green building and Energy conservation, as well as other ways of incorporating Renewable resources in the building process from start to finish.
Plastic recycling is the processing of plastic waste into other products. Recycling can reduce dependence on landfill, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions. Recycling rates lag those of other recoverable materials, such as aluminium, glass and paper. From the start of production through to 2015, the world produced some 6.3 billion tonnes of plastic waste, only 9% of which has been recycled, and only ~1% has been recycled more than once. Of the remaining waste, 12% was incinerated and 79% either sent to landfill or lost into the environment as pollution.
Reuse is the action or practice of using an item, whether for its original purpose or to fulfill a different function. It should be distinguished from recycling, which is the breaking down of used items to make raw materials for the manufacture of new products. Reuse – by taking, but not reprocessing, previously used items – helps save time, money, energy and resources. In broader economic terms, it can make quality products available to people and organizations with limited means, while generating jobs and business activity that contribute to the economy.
Cradle to Cradle: Remaking the Way We Make Things is a 2002 non-fiction book by German chemist Michael Braungart and US architect William McDonough. It is a manifesto detailing how to achieve their Cradle to Cradle Design model. It calls for a radical change in industry: a switch from a cradle-to-grave pattern to a cradle-to-cradle pattern. It suggests that the "reduce reuse recycle" methods perpetuate this cradle-to-grave strategy, and that more changes need to be made. The book discourages downcycling, but rather encourages the manufacture of products with the goal of upcycling in mind. This vision of upcycling is based on a system of "lifecycle development" initiated by Braungart and colleagues at the Environmental Protection Encouragement Agency in the 1990s: after products have reached the end of their useful life, they become either "biological nutrients" or "technical nutrients". Biological nutrients are materials that can re-enter the environment. Technical nutrients are materials that remain within closed-loop industrial cycles.
Michael Braungart is a German professor and businessperson. Braungart was founder of EPEA Internationale Umweltforschung GmbH in Hamburg, Germany, and co-founder of MBDC McDonough Braungart Design Chemistry in Charlottesville, Virginia.
Cradle-to-cradle design is a biomimetic approach to the design of products and systems that models human industry on nature's processes, where materials are viewed as nutrients circulating in healthy, safe metabolisms. The term itself is a play on the popular corporate phrase "cradle to grave", implying that the C2C model is sustainable and considerate of life and future generations—from the birth, or "cradle", of one generation to the next generation, versus from birth to death, or "grave", within the same generation.
There is no national law in the United States that mandates recycling. State and local governments often introduce their own recycling requirements. In 2014, the recycling/composting rate for municipal solid waste in the U.S. was 34.6%. A number of U.S. states, including California, Connecticut, Delaware, Hawaii, Iowa, Maine, Massachusetts, Michigan, New York, Oregon, and Vermont have passed laws that establish deposits or refund values on beverage containers while other jurisdictions rely on recycling goals or landfill bans of recyclable materials.
Upcycling, also known as creative reuse, is the process of transforming by-products, waste materials, useless, or unwanted products into new materials or products perceived to be of greater quality, such as artistic value or environmental value.
Commodity plastics or commodity polymers are plastics produced in high volumes for applications where exceptional material properties are not needed. In contrast to engineering plastics, commodity plastics tend to be inexpensive to produce and exhibit relatively weak mechanical properties. Some examples of commodity plastics are polyethylene, polypropylene, polystyrene, polyvinyl chloride, and poly(methyl methacrylate) .Globally, the most widely used thermoplastics include both polypropylene and polyethylene. Products made from commodity plastics include disposable plates, disposable cups, photographic and magnetic tape, clothing, reusable bags, medical trays, and seeding trays.
Recycling can be carried out on various raw materials. Recycling is an important part of creating more sustainable economies, reducing the cost and environmental impact of raw materials. Not all materials are easily recycled, and processing recyclable into the correct waste stream requires considerable energy. Some particular manufactured goods are not easily separated, unless specially process therefore have unique product-based recycling processes.
Avoided burden is an allocation approach used in life-cycle assessment (LCA) to assess the environmental impacts of recycled and reused materials, components, products, or buildings. While the approach has been adapted to fit a variety of LCA goals, it generally considers products with recycling or reuse potential and allocates the environmental impacts of their initial production to their final life cycle. The avoided burden method is never explicitly required for LCA under the International Organization for Standardization (ISO) or European Standards (EN). In fact, these organizations only require that an allocation approach be used to properly address reuse and recycling. In this case, LCA practitioners can choose to utilize the avoided burden method based on the goal and scope of their study.
IFCO trays are a type of reusable packaging for transporting fresh food produce. IFCO SYSTEMS is the name of the company that first developed a pooling service for reusable plastic trays for fresh produce in 1992, when the company was founded in Pullach, Germany. IFCO is the acronym for International Food Container Organization.
Sustainable furniture design and sustainable interior design is the design of a habitable interior using furniture, finishes, and equipment while addressing the environmental impact of products and building materials used. By considering the life-cycle impact of each step, from raw material through the manufacturing process and through the product's end of life, sustainable choices can be made. Design considerations can include using recycled materials in the manufacturing process, reutilizing found furniture and using products that can be disassembled and recycled or reclaimed after their useful life. Another method of approach is working with local materials and vendors as a source for raw materials or products. Sustainable furniture design strives to create a closed-loop cycle in which materials and products are perpetually recycled so as to avoid disposal in landfills.
Ecopreneurship is a term coined to represent the process of principles of entrepreneurship being applied to create businesses that solve environmental problems or operate sustainably. The term began to be widely used in the 1990s, and it is otherwise referred to as "environmental entrepreneurship." In the book Merging Economic and Environmental Concerns Through Ecopreneurship, written by Gwyn Schuyler in 1998, ecopreneurs are defined as follows:
"Ecopreneurs are entrepreneurs whose business efforts are not only driven by profit, but also by a concern for the environment. Ecopreneurship, also known as environmental entrepreneurship and eco-capitalism, is becoming more widespread as a new market-based approach to identifying opportunities for improving environmental quality and capitalizing upon them in the private sector for profit. "
Sustainable Materials Management is a systemic approach to using and reusing materials more productively over their entire lifecycles. It represents a change in how a society thinks about the use of natural resources and environmental protection. By looking at a product's entire lifecycle new opportunities can be found to reduce environmental impacts, conserve resources, and reduce costs.
Ecoleasing is a system in which goods are rented to a client for a certain period of time after which he returns the goods so the company that made it can recycle the materials.
China's waste import ban, instated at the end of 2017, prevented foreign inflows of waste products. Starting in early 2018, the government of China, under Operation National Sword, banned the import of several types of waste, including plastics with a contamination level of above 0.05 percent. The ban has greatly affected recycling industries worldwide, as China had been the world's largest importer of waste plastics and processed hard-to-recycle plastics for other countries, especially in the West.
Closed-loop recycling is the process by which a product or material can be used and then turned into a new product indefinitely without losing its properties during the recycling process.
