Maximizing Kitchen Efficiency through Zero-Waste Meal

Zero waste, or waste minimization, is a set of principles focused on waste prevention that encourages redesigning resource life cycles so that all products are repurposed (i.e. "up-cycled") and/or reused. The goal of the movement is to avoid sending trash to landfills, incinerators, oceans, or any other part of the environment. Currently 9% of global plastic is recycled. In a zero waste system, all materials are reused until the optimum level of consumption is reached. (USDA National Agriculture Library)

Zero waste refers to waste prevention as opposed to end-of-pipe waste management. It is a "whole systems" approach that aims for a massive change in the way materials flow through society, resulting in no waste. Zero waste encompasses more than eliminating waste through reducing, reusing, and recycling. It focuses on restructuring distribution and production systems to reduce waste. Zero waste provides guidelines for continually working towards eliminating waste. (EPA Environmental Resources)

Cradle-to-Grave

The cradle-to-grave is a linear material model that begins with resource extraction, moves to product manufacturing, and ends with a "grave" or landfill where the product is disposed of. Cradle-to-grave is in direct contrast to cradle-to-cradle materials or products, which are recycled into new products at the end of their lives so that ultimately there is no waste. (University of Minnesota Extension)

Cradle-to-cradle focuses on designing industrial systems so that materials flow in closed-loop cycles, which means that waste is minimized and waste products can be recycled and reused. Cradle-to-cradle goes beyond dealing with waste issues after it has been created by addressing problems at the source and redefining problems by focusing on design. The cradle-to-cradle model is sustainable and considerate of life and future generations. (Penn State Extension)

The cradle-to-cradle framework has evolved steadily from theory to practice. In the industrial sector, it is creating a new notion of materials and material flows. Just as in the natural world, in which one organism's "waste" cycles through an ecosystem to provide nourishment for other living things, cradle-to-cradle materials circulate in closed-loop cycles, providing nutrients for nature or industry. (USDA National Agriculture Library)

The spread of industrialization worldwide has been accompanied by a large increase in waste production. In 2012 the World Bank stated that 1.3 billion tons of municipal waste was produced by urban populations and estimates that the number will reach 2.2 billion tons by 2025 (Global Solid Waste Management Market - Analysis and Forecast). The increase in solid waste production increases the need for landfills. With the increase in urbanization, these landfills are being placed closer to communities. These landfills are disproportionately located in areas of low socioeconomic status with primarily non-white populations. Findings indicated these areas are often targeted as waste sites because permits are more easily acquired and there was generally less community resistance. Additionally, within the last five years, more than 400 hazardous waste facilities have received formal enforcement actions for unspecified violations that were considered to be a risk to human health. (EPA Environmental Resources)

Health

A major issue with landfills is hydrogen sulfide, which is released from the natural decay of waste. Studies have shown a positive association between increased lung cancer mortality rates and increased morbidity and mortality related to respiratory disease and hydrogen sulfide exposure. These studies also showed that the hydrogen sulfide exposure increased with proximity to the landfill.[better source needed] (University of Minnesota Extension)

Household chemicals and prescription drugs are increasingly being found in large quantities in the leachate from landfills. This is causing concern about the ability of landfills to contain these materials and the possibility of these chemicals and drugs making their way into the groundwater and the surrounding environment. (Penn State Extension)

Zero waste promotes a circular material flow that allows materials to be used over and over, reducing the need for landfill space. Through zero waste the number of toxins released into the air and water would be decreased and products examined to determine what chemicals are used in the production process. (USDA National Agriculture Library)

Zero waste promotion of a cyclical product life can help reduce the need to create and fill landfills. This can help reduce incidents of respiratory diseases and birth defects that are associated with the toxins released from landfills. Zero waste can also help preserve local environments and potable water sources by preventing pollutants from entering the ecosystem. (EPA Environmental Resources)

History

The California Integrated Waste Management Board established a zero waste goal in 2001. The City and County of San Francisco's Department of the Environment established a goal of zero waste in 2002, which led to the City's Mandatory Recycling and Composting Ordinance in 2009. (University of Minnesota Extension)

A group that would become the Zero Waste International Alliance (ZWIA) held its first meeting in 2002, chaired by British economist and environmentalist Robin Murray.[non-primary source needed] (Penn State Extension)

In 2008, Zero Waste was a term used to describe manufacturing and municipal waste management practices. Bea Johnson, a French American woman living in California, decided to apply it to her 4-person household. In 2009, she started the blog Zero Waste Home, and in 2010, was featured in The New York Times. (USDA National Agriculture Library)

The International Day of Zero Waste was adopted by the United Nations General Assembly on December 14, 2022. The event has been held annually on March 30 since 2023. "During International Day of Zero Waste, Member States, organizations of the United Nations system, civil society, the private sector, academia, youth and other stakeholders are invited to engage in activities aimed at raising awareness of national, subnational, regional and local zero-waste initiatives and their contribution to achieving sustainable development. The United Nations Environment Programme (UNEP) and the United Nations Human Settlements Programme (UN-Habitat) jointly facilitate the observance of International Day of Zero Waste."[non-primary source needed] (EPA Environmental Resources)

Packaging Examples

Milk can be shipped in many forms. One of the traditional forms was reusable returnable glass milk bottles, often home delivered by a milkman. While some of this continues, other options have recently been more common: one-way gable-top paperboard cartons, one-way aseptic cartons, one-way recyclable glass bottles, one-way milk bags, and others. Each system claims some advantages and also has possible disadvantages. From the zero-waste standpoint, the reuse of bottles is beneficial because the material usage per trip can be less than other systems. The primary input (or resource) is silica-sand, which is formed into glass and then into a bottle. The bottle is filled with milk and distributed to the consumer. A reverse logistics system returns the bottles for cleaning, inspection, sanitization, and reuse. Eventually, the heavy-duty bottle would not be suited for further use and would be recycled. Waste and landfill usage would be minimized. The material waste is primarily the wash water, detergent, transportation, heat, bottle caps, etc. While true zero waste is never achieved, a life cycle assessment can be used to calculate the waste at each phase of each cycle. (University of Minnesota Extension)

Online shopping orders are often placed in an outer box to contain multiple items for easier transport and tracking. This creates waste for every order, especially when there is only a single item. In response, some products are now designed not to require an outer box for safe shipping, a feature known as ships in own container. (Penn State Extension)

Recycling

It is important to distinguish recycling from zero waste. The most common practice of recycling is simply that of placing bottles, cans, paper, and packaging into curbside recycling bins. The modern version of recycling is more complicated and involves many more elements of financing and government support. For example, a 2007 report by the U.S. Environmental Protection Agency states that the US recycles at a national rate of 33.5% and includes in this figure composted materials. In addition, many multinational commodity companies have been created to handle recycled materials. At the same time, claims of recycling rates have sometimes been exaggerated, for example by the inclusion of soil and organic matter used to cover garbage dumps daily, in the "recycled" column. In US states with recycling incentives, there is constant local pressure to inflate recycling statistics. (USDA National Agriculture Library)

Recycling has been separated from the concept of zero waste. One example of this is the computer industry where worldwide millions of PC's are disposed of as electronic waste each year in 2016 44.7 million metric tons of electronic waste was generated of which only 20% was documented and recycled. Some computer manufacturers refurbish leased computers for resale. Community Organizations have also entered this space by refurbishing old computers from donation campaigns for distribution to undeserved communities. (EPA Environmental Resources)

A clear example of the difference between zero waste and recycling is discussed in Getting to Zero Waste, in the software industry. Zero waste design can be applied to intellectual property where the effort to code functionality into software objects is developed by design as opposed to copying code snippets multiple times when needed. The application of zero waste is straightforward as it conserves human effort. Also, software storage mediums have transitioned from consumable diskettes to internal drives which are vastly superior and have a minimal cost per megabyte of storage. This is a physical example where zero waste correctly identifies and avoids wasteful behavior. (University of Minnesota Extension)

Zero waste is poorly supported by the enactment of government laws to enforce the waste hierarchy. (Penn State Extension)

Significance of dump capacity

Many dumps are currently exceeding carrying capacity. This is often used as a justification for moving to Zero Waste. Others counter by pointing out that there are huge tracts of land available throughout the US and other countries which could be used for dumps. Proposals abound to destroy all garbage as a way to solve the garbage problem. These proposals typically claim to convert all or a large portion of existing garbage into oil and sometimes claim to produce so much oil that the world will henceforth have abundant liquid fuels. One such plan, called Anything Into Oil, was promoted by Discover Magazine and Fortune Magazine in 2004 and claimed to be able to convert a refrigerator into "light Texas crude" by the application of high-pressure steam. (USDA National Agriculture Library)

An example of a company that has demonstrated a change in landfill waste policy is General Motors (GM). GM has confirmed their plans to make approximately half of its 181 plants worldwide "landfill-free" by the end of 2010. Companies like Subaru, Toyota, and Xerox are also producing landfill-free plants. Furthermore, the United States Environmental Protection Agency (EPA) has worked with GM and other companies for decades to minimize waste through its WasteWise program. The goal for General Motors is to find ways to recycle or reuse more than 90% of materials by selling scrap materials, adopting reusable boxes to replace cardboard, and recycling used work gloves. The remainder of the scraps might be incinerated to create energy for the plants. Besides being nature-friendly, it also saves money by cutting out waste and producing more efficient production. Microsoft and Google are two other big companies that have Zero Waste goals. These two companies have goals to keep the majority of their waste out of landfills. Google has six locations that have a Zero Waste to Landfill goal. These locations have a goal to keep 100% of their waste out of landfills. Microsoft has a similar goal, but they are only trying to keep 90% of their waste out of landfills. All these organizations push forth to make our world clean and produce zero waste. (EPA Environmental Resources)

A garden centre in Faversham, UK, has started to prevent plastic plant pots from being passed down to customers. Instead, it reuses the plastic pots only locally in the garden center, but upon selling it to its customers it repots the plants in paper plant pots. It also sells plants wrapped in hessia and uses a variety of techniques to prevent handing down (single-use) plastics to customers (University of Minnesota Extension)

The waste sent to landfills may be harvested as useful materials, such as in the production of solar energy or natural fertilizer/de-composted manure for crops. (Penn State Extension)
