What is Waste Management?
Waste Management Is the collection, transport, processing or disposal, managing and monitoring of waste materials. The term usually relates to materials produced by human activity, and the process is generally undertaken to reduce their effect on health, and the environment. Waste management is a distinct practice from resource recovery which focuses on delaying the rate of consumption of natural resources. All wastes materials, whether they are solid, liquid, gaseous or radioactive fall within waste management
Waste management is becoming a bigger and bigger problem as life goes on. The definition of waste is something that is no longer useful or required. In other words its the leftovers. We have too much of these leftovers and not enough places to put them. The average person generates about 2kg of waste a day that's approximately 14kg of waste a week. Everyday landfills get bigger and bigger as more waste is generated and not managed properly. One day our world could end up as a huge landfill of its owncovered in so much garbage that we would be forced to leave. 1600 lbs of garbage takes up about the space of your refrigerator even after its crushed!! It takes a lot of money to deal with waste the way we are it can cost up to 4 million dollars to create a landfill. The general problem is that we don't have enough ways of dealing with waste and the way were dealing with it now will eventually destroy the world.
Factors Affecting Waste Management
There are many solutions that have come to deal with waste management but most of them have been cast off because of residents. Like incinerators or community recycling bins. No one wants anything like that near their house.
What is Waste?
Waste are items we don't need anymore and we discard. Waste comes in infinite sizes. There are many different types of Waste. We will go further in detail of each type of waste throughout the presentation.
Waste has been a major environmental issue everywhere since the industrial revolution. Humans rely on so many materials and almost all of them end up as waste. Everyone creates waste, although some people are very conscious and create less waste than others or vice versa some people generate more waste and don't think of waste management as a major issue. Well after this presentation, some people may look at waste management in a different way. Different countries handle waste in different ways. Common methods of waste management are Landfilling, Recycling and Composting. Other communities strongly prevent/control their waste generated in the first place. Now lets go further more in detail.
Waste management practices can
differ for developed and developing
nations, for urban and rural areas,and for
residential and industrial producers. Management
for non-hazardous waste residential and institutional
waste in metropolitan areas is usually the responsibility
of local government authorities, while management for
non-hazardous commercial and industrial waste is
usually the responsibility of the generator subject to
local, national or international controls.
There are many different ways that population affects waste management. The most common one is the size. A large population generates more waste therefore the waste is harder to get rid of and the landfills grow bigger. Where as a small population creates less waste so its easier to handle.
Landfills take up a lot of space especially old ones which have grown for a long time. If we keep making them then we wont have enough space for things we really want to build like houses or businesses.
It has been proven that in places with a low economy like Indonesia or Cuba generate more biodegradable waste like food. Places with high economy like Toronto generate lot of unrecylcable waste like plastic water bottles or toy packaging. This is because places with low economy can't afford to buy toys or fast food unlike the people in places with high economy.
How Waste Affects The Environment
Surface water contamination
Waste that gets into water bodies can negatively chemically change the water. It affects all ecosystems in the water and can cause harm to animals who drink from it.
Hazardous chemicals that get into soil can be soaked up by plants. This will harm the plants and humans and animals who eat them could be in danger too
Bad waste management can result in land and air pollution. This can be very bad for the environment and humans because we are the ones breathing it in
A Liquid that forms as water trickles through contaminated areas. It forms a very harmful mix of chemicals and may result in hazardous chemicals seeping into surface water groundwater or soil
Municipal well being
People don't want to live in or visit places that are gross and polluted. They want a nice clean fresh place. These places that are polluted do not attract investors or tourist so they usually have poor living conditions.
Cities that do not invest in recycling and proper waste control miss out on revenue from recycling. They also miss out on job opportunities that come from recycling, composting and businesses that work with them.
How many of you eat at fast food places?? How many of you actually separate your paper and plastics and food? How many of you just throw it all in one bin? 99 billion people are served at fast food places a year and every fast food restaurant makes proximity 100 000-One Hundred Thousand lbs of garbage a day. Now if you go to mcdonalds and you get lets say a burger, fries, a drink and maybe a cookie. Lets break all that garbage down your hamburger is gonna be wrapped in paper or in a box. Same with your fries. Those two things aren't the huge problem. Your drink may seem recyclable, but its really not. It has a wax seal on it so nothing spills through. Secondly you have the lid, which cannot completely be biodegradablee because no plastic can. Thirdly you have not just the straw but the wrapper around it. All this adds up. To top it all off about 4 billion of these cups a year that are all headed off to landfills. Another thing you might not think about while eating is condiment packets. Every single condiment even salt and pepper have their own separate garbage. That's yet another thing filling up our landfills. Lastly we would like to mention the food leftover on your garbage. Lots of the time grease and oils from food can collect on the surface of tanks at a recycling facility causing them to break or the recyclebles won't get accepted at all. Waste management facilities have thought about making machines to separate the food and garbage but it is all to expensive. So don't eat fast food its bad for you anyway.
Waste Management Flows in a Cycle
Is the disposal of non-recyclables into landfill. Landfill sites must be approved by legal authorities. Legal authorities guarantee that specific wastes are buried at the correct depth to avoid hazardous chemicals entering the soil, water tables, water systems, air, and pipe systems. In this step the raw materials made from recyclables are produced and sold as products on the market. Companies can purchase such products to further sustain the environment and natural resources. In conclusion, waste management is a science that addresses the logistics, environmental impact, social responsibility, and cost of an organization’s waste disposal. It is a detailed process that involves human resources, vehicles, government bodies, and natural resources.
Involves organization to guarantee that bin containers will not overfill and waste sit time does not become too long. The correct bin container size and service is a must to prevent overspill or excessive stinky smells. The correct bins for different wastes must be available with sticker and bin color identification. Locks, chains, lids and bars prevent public access and non-trained personnel putting rubbish in the incorrect bins. Cooperation between the waste company and customer is important. Bins must be accessible to the truck driver at the agreed times. Access to work premises outside work hours will cause an issue if unaddressed. Bin wheels can allow customers to move bins from convenient areas to serviceable locations.
Is the organizing of waste transport vehicles with the authorization and ability to transport the specified wastes from a customer’s work residence to landfill or processing plant. A waste must be transported by the vehicle designed for it. For example, general waste requires a vehicle with thicker compacter walls, to that of a cardboard and paper waste transporting vehicle. Therefore, a customer may require a series of vehicles to meet their waste management needs. Vehicles, drivers, and companies need licenses and approval in certain Council Areas to transport waste. EPA standards need to be upheld as well as General Public Safety. Safety standards are vital to the transportation of clinical and hazardous wastes. Drivers must undergo training for emergency circumstances that may arise.
Involves the separation of recyclables for treatment, and then after treatment are packaged as raw materials. These raw materials are sent to factories for production. Non-recyclable wastes by-pass this step and are delivered straight to landfill. Liquid and hazardous wastes are delivered to treatment plants to become less hazardous to the public and environment.
Is identifying the waste management needs, identifying recycling opportunities and ways to minimize waste output, and reviewing how waste minimization is progressing. Through keeping records of the different waste streams, a customer can see the results of their efforts in becoming more environmentally friendly, and a more efficient business.
Types of Waste
Solid waste is any garbage or rubbish that we make in our homes and other places. These include old car tires, old newspapers, broken furniture and even food waste. They may include any waste that is non-liquid.
Waste can come in non-solid form. Some solid waste can also be converted to a liquid waste form for disposal. It includes point source and non-point source discharges such as storm water and waste water. Examples of liquid waste include wash water from homes, liquids used for cleaning in industries and waste detergents.
Recycling is processing used materials (waste) into new, useful products. This is done to reduce the use of raw materials that would have been used. Waste that can be potentially recycled is termed "Recyclable waste". Aluminum products (like soda, milk and tomato cans), Plastics (grocery shopping bags, plastic bottles), Glass products (like glass bottles, broken glass), Paper products (used envelopes, newspapers and magazines, cardboard boxes) can be recycled and fall into this category.
Organic waste comes from plants or animals sources. Commonly, they include food waste, fruit and vegetable peels, flower trimmings and even dog poop can be classified as organic waste. They are biodegradable (this means they are easily broken down by other organisms over time and turned into manure). Many people turn their organic waste into compost and use them in their gardens.
Hazardous or harmful waste are those that potentially threaten public health or the environment. Such waste could be inflammable (can easily catch fire), reactive (can easily explode), corrosive (can easily eat through metal) or toxic (poisonous to human and animals). In many countries, it is required by law to involve the appropriate authority to supervise the disposal of such hazardous waste. Examples include fire extinguishers, old propane tanks, pesticides, mercury-containing equipment (e.g, thermostats) and lamps (e.g. fluorescent bulbs) and batteries.
and other Resources
Substances unsafe to use commercially, industrially, agriculturally, or economically that are shipped.
transported to or brought from the country of origin for dumping or disposal in, or in transit through.
Substances safe to use commercially, industrially, agriculturally, or economically that are shipped, transported to or brought from the country of origin for dumping or disposal in, or in transit through
Biodegradable v.s Non-biodegradable
Biodegradable waste is waste that can break down into natural components and be recycled into the life cycle naturally examples are old vegetables / food, paper, cardboard, deceased animals, and phyto plastics ( special plastics that break down when exposed to the sun after some time) etc.
Non biodegradable waste is waste that does not break down into natural components and exists in the environment for a long time. Examples would be tires, plastics, electronic components, metals etc.
How does this issue effect the human environment?
The relationship between the amount of waste generated and economic growth has meant that the greater the wealth will make it greater the consumption of goods and services which means more waste produced in the environment.
some key goal is to ‘decouple’ waste generation from economic growth. Waste generation can be decoupled by the following three points:
increasing the resource efficiency of goods and services by using fewer resources in production
decreasing the resource of the wast will intensity in the production of goods and services through improved processes, designs, and materials.
The efficient use of our valuable natural resources will saves us money, this would reduces our impact on the environment, and ensures that our goods and services are competitive.
How does the issue affect the physical environment?
By carefully managing the waste pollution, we can help avoid things like plants dying, water and soil acidity levels becoming high, acid rain, water discoloration, and oil spills.
some diseases that are caused by pollution that harm people are dysentery, cholera, cancer and much more.
Instead of incorporating waste management only as a means of cleaning up the mess which was created by humans, it would be far smarter and more cost-effective to avoid waste management by integrating an effective waste management plan from the start.
People are beginning to realize that the solution with the waste lies in
using garbage as a Resource rather than refuse the waste to be destroyed.
What are possible solutions to this issue?
What are possible solutions to this issue?
Each person adds to the waste management problem. If each household reduces its waste, the problem it will be reduced. You can start by analyzing what you throw away at home to stop waste management.
The government could affect waste management in a number of ways by saying the following sentences: establishing national recycling goals, packaging standards, adopting a clearly stated policy on source reduction.
The federal government could also set an example and stimulate markets for recycled products by recycled materials example of this materials are plastic bottles, paper and plastic and more, all of this materials that were listed are bad for the environment.

This simply means burning waste. This method is common in countries with limited landfill space. Incineration chambers can be small for domestic use, but there are large ones for municipal use as well. It is great for treating waste with contamination (like those from hospitals) and hazardous waste from factories, but the method produces too much carbon dioxide which is BAD! Modern incineration processes are more efficient and release less dioxin than home fireplaces and backyard barbecues. This method is very common in Denmark, Germany and the Netherlands. This method is effective in some ways while, on the other hand it is very dangerous for the environment.When you burn a pile of garbage in an incinerator about a quarter comes out as ash. This ash can be dangerous filled with many toxins like metal or plastics. Another thing is the toxic smoke that's released into the air. We breath it in as we pass by industrial places. All that burned up led, plastic who know what other disgusting things getting sucked into to our lungs with every breath. Incinerators are not a solution they are a problem.
Hopefully you now realize how big of a deal waste management i. It is causing global warming, pollution , diseases , soil contamination , and much. Now when you recycle start separating plastics and papers, don't litter and use reusable things like containers or water bottles. Thank you for listening! I hope you enjoyed my presentation.
Generally, this term means a large piece of land away from living places where all the waste from a town is deposited. But there is more to landfills. Proper landfill management involves sorting out all the waste (waste separation), and sending only the waste that cannot be recycled and composted to the site.
Proper landfills, are also lined at the bottom to minimize the leakage of soil pollutants and other toxins from getting into the water table. This method is effective, but expensive and difficult.
In many towns, sorting is not done, and all the waste (paper, food, diapers, glass) is mixed up and deposited. That is a problem because, glass, and plastics take thousands of years to decompose. Additionally, the landfills soon become full, smelly and unsafe for the environment.
Proper waste management is not cheap, but it is something we all have to get involved and discuss it. The effect of not getting involved can be catastrophic to our health and environment.
Did You Know Facts
Did you know?
Europe creates about over 1.8 billion tonnes of waste each year. This means each person creates about 3.5tonnes on average.
In 2010, Americans generated about 250 million tons of trash and recycled and composted over 85 million tons of this material, equivalent to a 34.1 percent recycling rate.

Especially if we have got someone else to pick up our trash/waste.
Most of us don't think so much about trash. Isn't it?
After my presentation, after learning more about waste, you will hopefully think twice before throwing out all your un-needed things.
Lets have a look of what's in the Landfill.
Who is benefiting from the development?
Nobody wants waste because waste is items/objects that are unnecessary or not needed. Therefore, the only people benefiting from Waste Management is the people who own the place/country/land that is being used to get rid of waste. Nobody wants to keep junk! You want to get rid of it. Either it goes to the nearest landfill or any other ways of managing waste (Burning/Incineration). But in order to make all the waste go to that landfill, we need permission from the people who own the landfill and then they get paid for managing the waste. Therefore, people/association who own the Landfill are benefiting.
Any other individuals/industry/company benefiting from the development?
The people who actually take your trash are actually benefiting from this development because without this development they wouldn't have a job. Therefore, it provides jobs. They gain money from coming and picking up your garbage from your house, so that its not your worry at home. Imagine if these people didn't do their jobs... Our homes would be a landfill of its own. It would cause even more issues/problems. That's why we should take Waste Management seriously and do our best to manage it carefully and safely so that it doesn't affect our environment and cause any further issues.
Who are the people who take our trash?
of Canada is the leading provider of comprehensive waste management services, offering advanced residential, commercial and industrial collection, recycling and disposal services throughout Canada.
How many Landfills are there in Canada?
Canada has over Ten Thousand landfill sites.
How much Garbage?
Most of Toronto's garbage goes to a landfill in Michigan or other landfills. Canadians generate approximately 31 million tonnes of garbage a year and
only recycle about 30 per cent of that material
• This means that each person generates approximately 2.7 kg of garbage each
• The sheer volume of waste means that many existing landfill sites are
approaching capacity, and few people want new sites built near their
What is the Solution?
REDUCE, REUSE, RECYCLE!
How Long Does it Take?
Takes 500 years to disintegrate.
Takes 80 years to breakdown.
Takes 100 years to dissolve a tin can.
Takes 1 Million years to break down.
Takes 1 million years to break down naturally.
Waste management is NOT sustainable for the future because our government doesn't look at Waste Management as their problem. They seem to be lazy and don't want to properly manage waste.
We will have to be contributing to a more sustainable world by:
advancing technologies to reduce waste
increasing recycling and reuse
creating even safer treatment and disposal options
developing sources of renewable energy
When we Think Green, we think of a world as ...
where there are so many clean, alternative ways to produce power that the threat of exhausting our natural resources is forever put to rest.
where “reduce, reuse, and recycle” become the watch words of every family and company in North America.
where companies take a leadership position by investing in cleaner technologies so that air pollution becomes a thing of the past.
where the environment is respected and every action is aimed at recovery and restoration.
where Waste Management partners with its customers to use our knowledge and experience to their benefit and the benefit of the planet, leading them to new, sustainable solutions and working with every link in the supply chain to address the entire life cycle of a product.
where Waste Management’s commitment to excellence and leadership has positioned us to deliver lasting solutions to the environmental challenges our planet will face in the 21st century.
For those of you who wonder what a Diversion rate is..... The Diversion rate is the percentage of waste materials diverted from traditional disposal such as landfilling or incineration to be recycled, composted, or re-used.
The graph to the left shows how the residential sector diversion rate got lower then went higher. The Non-Residential Sector Diversion Rate decreased over the years. And the total Diversion rate barely moved throughout the years.
The graph to the left shows the relationship between how much water bottles we buy and how many water bottles we actually recycle.
The graph above shows the relationship between collection/transportation, Operation of recycling facilities, Operation of disposal facilities, Operation of organics processing facilities for each local government and how many dollars were spent in the process of waste management.
Thank you for Watching! I hope you enjoyed my presentation!
