San Francisco Mandatory Recycling And Composting Ordinance
The San Francisco Mandatory Recycling and Composting Ordinance (No. 100-09) is a local municipal ordinance requiring all persons located in San Francisco to separate their recyclables, compostables and landfilled trash and to participate in recycling and composting programs. Passed by the San Francisco Board of Supervisors in 2009, it became the first local municipal ordinance in the United States to universally require source separation of all organic material, including food residuals. History Early 1900s The roots of San Francisco's recycling and composting program can be traced back to the formation of the Scavengers Protective Union in 1879, when loose federations of scavengers began. Most were Italian immigrants from one region of Italy and they hauled municipal waste in horse-drawn wagons and hand separated valuable discards for resale. The scavengers made a living from materials similar to those salvaged in recycling programs today such as wood, metals, glass, rags, yard ...

Compostable Plastic
Biodegradable plastics are plastics that can be decomposed by the action of living organisms, usually microbes, into water, carbon dioxide, and biomass. Biodegradable plastics are commonly produced with renewable raw materials, micro-organisms, petrochemicals, or combinations of all three. While the words "bioplastic" and "biodegradable plastic" are similar, they are not synonymous. Not all bioplastics (plastics derived partly or entirely from biomass) are biodegradable, and some biodegradable plastics are fully petroleum based. As more companies are keen to be seen as having "Green" credentials, solutions such as using bioplastics are being investigated and implemented more. However there are many skeptics who believe that bioplastics will not solve problems others expect. History Polyhydroxyalkanoate (PHA) was first observed in bacteria in 1888 by Martinus Beijerinck. In 1926, French microbiologist Maurice Lemoigne chemically identified the polymer after extracting it from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Law In The San Francisco Bay Area
Law is a set of rules that are created and are law enforcement, enforceable by social or governmental institutions to regulate behavior,Robertson, ''Crimes against humanity'', 90. with its precise definition a matter of longstanding debate.

State-enforced laws can be made by a group legislature or by a single legislator, resulting in statutes; by the executive through decrees and regulations; or established by judges through precedent, usually in common law jurisdictions. Private individuals may create legally binding contracts, including arbitration agreements that adopt Alternative dispute resolution, alternative ways of resolving disputes to standard court litigation.

Environment Of California
The environment of California describes results of human habitation of the American State of California. History of environmental action California's Mediterranean climate makes vegetation susceptible to wildfires through the dry summers. Aboriginal Californians used fire to control brush, promote growth of seed-producing plants important to subsistence, and perhaps as an aid to hunting wildlife. These periodic fires kept woodland areas relatively open until 20th century laws curtailed burning in an effort to protect structures. European crops and livestock were introduced with missions along the coast from San Diego to San Francisco Bay through the late 18th and early 19th century. The California Gold Rush caused explosive population growth making San Francisco the only 19th century city west of St. Louis, Missouri.Donley, Allan, Caro, and Patton ''Atlas of California'' (1979) pp.9-19 Water soon became the limiting factor for population growth, and early laws estab ...

Plastic And Styrofoam Contamination In Municipal Compost
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1 ...

Carbon Sequestration
Carbon sequestration is the process of storing carbon in a carbon pool. Carbon dioxide () is naturally captured from the atmosphere through biological, chemical, and physical processes. These changes can be accelerated through changes in land use and agricultural practices, such as converting crop land into land for non-crop fast growing plants. Artificial processes have been devised to produce similar effects, including large-scale, artificial capture and sequestration of industrially produced using subsurface saline aquifers, reservoirs, ocean water, aging oil fields, or other carbon sinks, bio-energy with carbon capture and storage, biochar, enhanced weathering, direct air capture and water capture when combined with storage. Forests, kelp beds, and other forms of plant life absorb carbon dioxide from the air as they grow, and bind it into biomass. However, these biological stores are considered volatile carbon sinks as the long-term sequestration cannot be guaran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Greenhouse Gas Emissions
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely follow ...

Global Warming Solutions Act Of 2006
The Global Warming Solutions Act of 2006, or Assembly Bill (AB) 32, is a California State Law that fights global warming by establishing a comprehensive program to reduce greenhouse gas emissions from all sources throughout the state. AB32 was co-authored by then-Assemblymember Fran Pavley (D-Agoura Hills) and then-Speaker of the California Assembly Fabian Nunez (D-Los Angeles) and signed into law by Governor Arnold Schwarzenegger on September 27, 2006. On June 1, 2005, Governor Schwarzenegger signed an executive order known as Executive Order S-3-05 which established greenhouse gas emissions targets for the state. The executive order required the state to reduce its greenhouse gas emissions levels to 2000 levels by 2010, to 1990 levels by 2020, and to a level 80% below 1990 levels by 2050. However, to implement this measure, the California Air Resources Board (CARB) needed authority from the legislature. The California State Legislature passed the Global Warming Solutions Act ...
