Study Notes
The Problem with Landfills and Incineration
-
Waste production has increased due to consumption, with 7 billion people producing more garbage than ever before.
-
Landfills are a common method of waste disposal, historically used to bury trash, but now often in the form of uncontrolled dumping.
-
Landfills, like the one in Beirut, can reach over 40 meters in height and leach chemicals into the ground and air, affecting communities and their livelihoods.
-
Waste pickers often work in these landfills, searching for recyclable materials among the putrid mounds.
-
Landfills are expanding, with 80% of the UK population living within two kilometers of one, causing air and water pollution.
-
Even well-managed landfills can cause problems, with toxic chemicals leaching into groundwater and potentially causing birth defects.
-
Incineration is a widely used alternative to landfills, with approximately 800 municipal incinerators worldwide.
-
Incineration can convert waste into gas, ash, heat, and electricity, but toxic chemicals can escape into the environment.
-
In developed countries, incinerators are subject to strict monitoring, but some scientists have campaigned against incineration due to the risk of toxic emissions.
-
The Thune incinerator in Iceland was recently shut down due to high levels of chemical emissions, causing concern for nearby residents.
-
Halogenated dioxins, produced by burning certain types of rubbish, are a concern as they do not occur naturally and are extremely toxic.
-
The need to reduce waste production and find better solutions for waste disposal is crucial for environmental and public health.The Dangers of Incineration and Dioxins
-
European incinerators must have pollution controls, but the filters needed are expensive.
-
All incinerators produce toxic ash, including bottom ash and fly ash, with the latter being extremely toxic.
-
Incineration is estimated to cause 50-80% of the world's dioxin contamination.
-
Farmers near incinerators are at high risk of contamination, which can enter the food chain.
-
A farmer whose herd was contaminated by an incinerator was forced to confine and eventually put down his animals.
-
The incinerator was emitting unacceptably high levels of dioxins, which were found in the food chain.
-
Incinerator operators regularly violate emission limits, even state-of-the-art ones.
-
A French town fought for justice after an incinerator released dioxins a thousand times above permitted limits.
-
Exposure to dioxins can cause deformities and health issues in humans and animals.
-
Ultra-fine particles emitted by incinerators, which cannot be captured, are a growing concern.
-
Nanoparticles can travel through the body and have toxic effects, even at low concentrations.
-
The environment already has too many toxins, and sources should be cut back to reduce contamination.The Environmental Impact of Plastic Waste on Our Oceans
-
Cigarette butts are made of non-biodegradable cellulose acetate and release toxins into water, which can harm water fleas and fish.
-
Annually, 260 million tonnes of plastic are used, and over 30% of that material is thrown away within a year.
-
Indonesia's Jakarta produces a significant amount of garbage, which ends up in the waters of the Chilawang River, contaminating it for 20 years.
-
The Great Pacific Garbage Patch, situated in an ocean gyre in the North Pacific, covers an area of 20 million square kilometers, with plastic fragments that have been eroded into tiny pieces.
-
Plastic waste is found all over the world's oceans, with the United Nations estimating 46,000 pieces per square kilometer on average.
-
Plastic bags, even those labeled degradable, do not biodegrade and can still harm marine life by breaking down into smaller fragments that can be ingested.
-
A study found that 83 out of 120 Dublin berry prawns caught in the Clyde estuary contained plastic filaments or pieces of plastic bags in their stomachs.
-
Plastic can leach chemicals into the water and attract other hydrophobic chemicals, potentially making it even more dangerous to marine life.
-
These chemicals can disrupt hormones, suppress immune systems, and decrease reproductive rates in marine life.
-
Eating small fish can lead to biomagnification, where the pollutants stored in fatty tissue accumulate in larger predators, such as killer whales.
-
Marine mammals, such as whales, dolphins, and porpoises, are affected by plastic pollution, which accumulates at every level of the food chain.
-
The impact of plastic waste on our oceans is only beginning to be understood, and society needs to recognize the ecological impact it is having on our environment.The Urgent Need for Sustainable Waste Management
-
Marine mammals, such as dolphins and killer whales, have high levels of pollutants in their bodies due to biomagnification, and this could lead to massive population declines.
-
Plastic waste in the ocean is a major problem, and it is a warning sign that we need to address waste management.
-
The packaging industry needs to prioritize end-of-life recyclability to tackle the problem of waste.
-
Individuals can make a difference by making conscious decisions about their shopping habits and reducing their waste.
-
Refilling containers is a sustainable alternative to packaging waste, and it is a good business model that benefits everyone.
-
Food waste is a significant problem, and anaerobic digestion can turn it into energy and fertilizer.
-
San Francisco has implemented a zero-waste initiative that requires everyone to participate in source separation of waste, and they work closely with businesses to achieve their goal.
-
Recycling centers, such as Recycle Central, provide good jobs with full benefits and pensions.
-
The materials sent to Asia in shipping containers historically went back empty, but now they go back with materials that were sent from San Francisco.
-
Composting is an affordable and effective way to improve soil quality, increase yields, and reduce methane production from landfills.
-
Sustainable waste management could save the UK economy 6.4 billion pounds annually and divert 17 million tons of waste from landfills and incinerators.
-
There is an urgent need to prioritize sustainable waste management to address the single biggest challenge to our civilization.
