Could you live without plastics?

More than 380,000,000 tons of plastics is produced annually worldwide; more than one million tons a day. If a 120 car train could load up 10,000 tons of plastic it would require more than 100 trains to transport all that plastic products just for daily consumption!

Holy cow! What can ya do?

    I think plastic shipping bags should be outlawed and 100 dollar fine for the first offense if seen walking along mean. To be donated to the warfare and welfare of recyclable polyeruthenes.
     

    topic 8.3: solid domestic waste

    Pictureimage from www.scrd.ca
    Domestic solid waste, commonly known as trash or garbage (US), refuse or rubbish(UK) is a waste type consisting of everyday items that are discarded by the public. The organic waste potions consist of food and kitchen waste, yard trimmings or other garden waste. Inorganic waste  consists of paper, corrugated cardboard, plastic, glass, wood, and metal products such as drink cans.

    In this unit we will look at your contribution to domestic waste as well as the waste contributed by our community. We will also look at different management strategies in dealing with domestic waste.

    ​This unit is a minimum of 3 hours.

    Knowledge and Understanding:
    8.3.U1 There are different types of SDW, the volume and composition of which changes over time
    [    SDW includes household waste such as paper, glass, metal, plastics, organic (kitchen or garden) packaging, construction debris, and clothing]
    • Define solid domestic waste
    • List examples of solid domestic waste
    • Describe and explain the changes in the volume and composition of SDW over time
    Picture
    Human activities produce a wide range of waste from an equally wide range of activities.Solid domestic waste is the waste generated from households. This does not include industrial waste that is produced from industrial processes This material can be made up of: 
    • paper
    • cardboard
    • metal, glass
    • plastics
    • e-waste
    • household chemicals

    Garbage: the four broad categories:
    • Organic waste: kitchen waste, vegetables, flowers, leaves, fruits.
    • Toxic waste: old medicines, paints, chemicals, bulbs, spray cans, fertilizer and pesticide containers, batteries, shoe polish.
    • Recyclable: paper, glass, metals, plastics.
    • Soiled: hospital waste such as cloth soiled with blood and other body fluids.

    ​As we become more technologically advanced, we produce materials that can withstand extreme temperatures, are durable and easy to use. Plastic bags, synthetics, plastic bottles, tin cans, and computer hardware- these are some of the things that make life easy for us.

    Non-biodegradable waste is a type of waste that can not be broken down into its base compounds by micro-organisms, air, moisture or soil in a reasonable amount of time. Non-biodegradable waste is an environmental concern, as it threatens to overwhelm landfills and create disposal problems.

    For many years, most manufacturers and production facilities have operated using a linear economy. This ‘take, make, dispose’ method of manufacturing means that instead of recycling the raw materials and any waste associated with the production process, they are disposed of instead.

    Not only does a linear economy product a huge amount of unwanted, and sometimes dangerous landfill waste, it also puts a lot of pressure on the country’s plummeting resources as new raw materials need to be found and utilized

    8.3.U3 Waste disposal options include landfills, incineration, recycling and composting
    • Discuss the waste disposal options - landfill, incineration, recycling and composting.​
    Picture
    There are eight major groups of waste management methods, each of them divided into numerous categories. Those groups include source reduction and reuse, animal feeding, recycling, composting, fermentation, landfills, incineration and land application. You can start using many techniques right at home, like reduction and reuse, which works to reduce the amount of disposable material used
    • Landfills - Throwing daily waste/garbage in the landfills is the most popularly used method of waste disposal used today. This process of waste disposal focuses attention on burying the waste in the land.
    • Incineration/Combustion - a type disposal method in which municipal solid wastes are burned at high temperatures so as as to convert them into residue and gaseous products. The biggest advantage of this type of method is that it can reduce the volume of solid waste to 20 to 30 percent of the original volume, decreases the space they take up and reduce the stress on landfills.
    • Recovery and Recycling - process of taking useful discarded items for a specific next use. These discarded items are then processed to extract or recover materials and resources or convert them to energy in the form of useable heat, electricity or fuel.
    • Composting - a easy and natural bio-degradation process that takes organic wastes i.e. remains of plants and garden and kitchen waste and turns into nutrient rich food for your plants.

    8.3.U4 There are a variety of strategies that can be used to manage SDW (reference to figure 3) influenced by cultural, economic, technological and political barriers. There strategies include 1) altering human activity - for example, through a reduction of consumption and composting of food waste, 2) controlling the release of pollutant - governments create legislation to encourage recycling and reuse initiative and impose taxes for SDW collection and on disposable items, 3) reclaiming landfills, using SDW for waste to energy programs implementing initiatives to remove plastics from the Great Pacific garage patch (clean-up and restoration)
    • Compare and contrast the various pollution management strategies for SDW.
    • Discuss the impact of culture, economics, technology and political attitudes on the choice of SDW management strategies employed by a society.
    Picture
     
    Pollution management strategies that should be considered are recycling, incineration, composting and landfill.

    Cause
    Reduce - Reduce packaging
    Reuse - Choose second hand materials or reusable containers
    Recycle - Choose materials that can be recycled
    Composting - Organic can be composted at source. Choose biodegradable materials

    Effect
    Incineration  - Easy and Quick. Releases greenhouse gases such as methane which could be used for powering but can produce toxic pollutants
    Landfill - Might pollute groundwater through leeching. We are facing less available space
    Sealed landfill - Prevent leeching but higher costs. There is limited space
    Composting - Can turn organic wastes into resources

    Application and skills:
    8.3.A1 Evaluate SDW disposal options
    Strategies for dealing with SDW: 
    Composting
    Advantages
    Disadvantages
    • Reduces amount of waste in landfills
    • Low cost
    • Composting can be done at the commercial and industrial levels, but also on a household level 
    • ​Creates fertile soils
    • Decrease the use of synthetic fertilizers (which has it’s own environmental issues it causes)
    • Improves soil porosity and water retention
    • If not done correctly can attract pests
    • ​Requires public buy in
    • Only for organic matter
    •  Windrow and aerated static pile composting require relatively large areas, and odor control is a common problem.
    • Residential composting bins can get very dirty, and be hard to clean
    • Amount of effort involved. All the materials must be carried to the compost pile, 
    Recycling
    Advantages
    • Prevents the loss of useful raw materials.
    • Reduces the consumption of new raw materials.
    • Reduces energy usage in some areas (though collection and processing does use energy).
    • Creates Green jobs
    • Reduces pollution at the extraction phase of the process - getting the raw materials out of the ground.
    • Lowers the release of greenhouse gases.
    • materials are collected, separated, and processed first. Success depends on how much energy and raw materials are required to produce the material in the first place.
    • plastics
    • glass can be melted and re-shaped into new bottles or jars indefinitely; this requires less energy than making new bottles and jars
    • paper 
    • metals (aluminum is most common and cost-effective material for recycling; steel is also frequently recycled
    Disadvantages
    • Requires public buy in
    • Not always cost effective
    • Building up a new waste recycling unit takes up a lot of capital.
    • Products may not be as durable. These kinds of products are almost always made of trashed waste material collected from other waste materials that have been overly utilized and fragile. This makes products of recycled waste less durable and low priced.
    • Locations where every manner of waste is piled provides a nice ground for the formation of debris and spread of infectious diseases
    Incineration 
    Advantages
    • SDW burned at very high temperatures. Very useful for clinical waste and any hazardous waste containing pathogens
    • Landfill space is running out. Incineration can burn up to 90% of the total waste generated in a chosen area
    • Dioxin emissions from incineration have been reduced with new technology.
    • Can be used to produce electricity (‘waste-to-energy’ plants)
    • Takes up much less space than landfills.
    • ​Reduces the volume of waste by 80 – 85% therefore it is very popular in countries where land is scarce e.g. Japan.
    • Used to generate local district heating. Sweden generates 8% of its heating needs from waste incinerators..
    • Can function in any type of weather
    • Bottom ash can be recycled and used to build roads 
    • Avoids the methane emissions of landfills.
    • Incineration doesn’t add any toxic elements to the groundwaterIncineration plants retrieve metal form the ashes and this can then be recycled.
    • Nutrients returned to soils in agriculture, parks, or home gardens
    • Already used on large-scale basis in many MEDC 
    • Many people in LEDC’s live on the tips and make a living sifting through the waste. Incinerators take away this livelihood. 
    Disadvantages
    •  Toxic fly ash is difficult to dispose of safely and adds waste miles (distance the waste is transported) as it is moved to landfills.
    •  Emits smoke from the chimneys includes nitrogen oxide, particulates, heavy metals, acid gases and the carcinogen dioxin.
    • May produce dioxins and heavy metal deposits from materials burned​
    • New incinerators are taking away the funding from other renewable energy research and development.
    • Old incinerators emit dioxin and furan. These are toxic gases which have been cited as being carcinogenic. 
    • ​Causes property devaluation in the surrounding areas. 
    •  Causes visual pollution due to the intrusive chimney stack.
    • There are some concerns as to the safety levels of bottom ash and the UK Highway Authority has banned its use in concrete work.
    •  Filters do not remove the finest particles from air emissions.
    • Set up costs are very high.
    Landfills
    Advantages
      • ​Primary way SDW is disposed of
      • Initially cheap, but costs increasing rapidly as sites fill up
      • Methane from decomposition may be captured for energy production. Used to generate local district heating in Denmark and Sweden.
      • Old landfill sites can be landscaped and re-used for building projects. 
      • Creates jobs for the local community - though they are usually unskilled and low paid jobs 
      •  Landfill sites that are close to settlements reduce the cost of transporting the waste
    Disadvantages
    •  Landfill sites give off dangerous gases that cause air pollution and global warming (methane). There is also the potential for explosions if methane is allowed to build up. 
    • ​Liners can fail and leachate leak into the local environment and groundwater sources.
    • Settling after compaction can cause problems for future uses – must be left a long time to settle fully.
    • Most landfill sites close to populations are full so waste collection vehicles have to travel a long way to alternative sites.
    •  Landfills are filling up. Even with daily compaction of waste the life span of landfills is limited.
    • Poorly managed sites cause problems with vectors such as rats, mice and flies increasing the spread of diseases.
    • Heavy vehicles cause traffic problems and damage local roads.
    • Poorly managed sites cause problems with dust, odor, visual and noise pollution - these can negatively impact local property prices in the area.
    • Contribute to marine debris - the litter that ends up in seas and oceans as it blows off poorly managed sites.
