2. Reflections about the movie „The Age of Stupid‟



2.1 Niel

The movie the age of stupid is more a documentary than a movie.



During the movie you see different parts of documentaries about the earth.



They let a old man tell his story in the French Alps, a man who survived the

hurricane, an African women tells also how Shell destroyed her life and that

form her fellow village habitants.



The last part goes about a little boy whose father is killed by the American army

and now his life goal is to kill American soldiers.







2.2 Thomas

The movie is actually a documentary about our planet. Since I don‟t like

documentaries, I didn‟t like the movie very much. I like the way the movie was

made, but I don‟t like the movie on its own. The man who tells the story plays

his roll very good and is a very good actor.



There are six main stories. Among them that of a French mountain guide, an

Indian entrepreneur, a British wind-energy developer and some other story.

3.1 Definition



3.1.1 Explanation

Waste management is the collection, transport, processing, recycling or

disposal1, and monitoring of waste materials. The term usually relates to

materials produced by human activity, and is generally undertaken to reduce

their effect on health, the environment or aesthetics2. Waste management is

also carried out to recover resources from it. Waste management can involve

solid, liquid, gaseous or radioactive substances, with different methods and

fields of expertise for each.



3.1.2 Problem

The problem of Domestic Waste is drawing increasing attention of the people as

huge garbage is lying down uncollected beside the roads, streets dustbins

and on the ground which is causing threat to the environment as well as

endangering public health.



This waste is generated as consequences of household activities such as the

cleaning, cooking, repairing empty containers, packaging, huge use of plastic

carry bags. Many times these waste gets mixed with biomedical waste from

hospitals and clinics. There is no system of segregation3 of organic, inorganic

and recyclable wastes at the household level. Door-to-door collection is

rarely practiced community collection bins are poorly managed and are

usually no more than open dumps on the roadside.



The problem with domestic waste in homes is that the people don‟t recycle as

they are told. The wrong things manage to get in the wrong garbage cans.

This leads to the problem that the collection has. They have to sort out the

wrong things out of the wrong garbage cans. It takes time and people to do

this.







4. Evolution



4.1 Past

In early pre-industrial times waste was mainly composed of ash from fires,

wood, bones, bodies and vegetable waste. It was disposed of in the ground

where it would act as compost and help to improve the soil. Ancient

rubbish dumps excavated4 in archaeological digs reveal only tiny

amounts of ash, broken tools and pottery. Everything that could be was

repaired and reused, populations were smaller, and people lived in less

concentrated groups. However, the transition from nomadic5 hunter-

gatherer to farmer meant that waste could no longer be left behind, and

it soon became a growing problem.



Until the Industrial Revolution when materials became more available

than labour, reuse and recycling was commonplace6. Nearly 4000 years ago

there was a recovery and reuse system of bronze scrap in operation in Europe

and there is evidence that composting was carried out in China. Reuse and

recycling has always existed in the form of salvage, an ages-old tradition

stretching forward to the Rag-and-Bone men. Traditionally, recovered

materials have included leather, feathers and down, and textiles. Recycling

included feeding vegetable wastes to livestock and using green waste as

fertiliser. Pigs were often used as an efficient method of disposing of

municipal waste. Timber was often salvaged and reused in construction and

ship-building. Materials such as gold have always been melted down and re-

cast numerous times. Later recovery activities included scrap metal, paper

and non-ferrous metals.

4.2 Present

Since the 1980's, household waste arisings in the UK have risen from just under

400 Kg per person to over 500 Kg per person per year. Such an increase can

be attributed to economic growth, social change, and waste collection

methods. The increase in waste has closely mirrored that of Gross Domestic

Product (GDP), while the increase in single person households and increase in

wheeled bin household waste collections have exacerbated7 the problem.



Today in the UK it is estimated that each household throws away over a tonne of

waste annually. In addition, for every tonne of products we buy, ten tonnes of

resources are used to produce them. Around 70% of our household waste has

the potential to be either recycled or composted. Despite the fact that the

majority of the general public regard recycling as worthwhile,

and that over 65% of households have access to kerbside

collection recycling schemes, only 14.5% of dustbin

contents are recycled or composted.



4.3 Future

However, as city populations increased, space for disposal

decreased, and societies had to begin developing waste

disposal systems.



There are 2 scenario‟s for the future:



•Scenario A: waste deposit at the landfill8 with „implementation 9of domestic

waste separation and recycling‟.



•Scenario B: waste removal to a landfill with „multi-treatment: household

separation, recycling and energetic recovery‟.



Three levels of waste treatment were proposed. The first level was

implementation of the recycling system, which included household waste

separation. The next step involved mechanical-biological treatment. The third

level was the construction and operation of a new waste incineration plant in

Kaunas. Two sites in Kaunas city were proposed; however, more detailed

analysis, including the economic factors, will need to be done.









5. Current events



5.1 Europe



5.1.1 Methods of disposal



Integrated waste management

Integrated waste management using LCA (life cycle analysis) attempts to offer

the most benign options for waste management. For mixed MSW (Municipal

Solid Waste) a number of broad studies have indicated that waste

administration, then source separation and collection followed by reuse and

recycling of the non-organic fraction and energy and compost/fertilizer

production of the organic waste fraction via anaerobic digestion to be the

favoured path. Non-metallic waste resources are not destroyed as with

incineration, and can be reused/ recycled in a future resource depleted

society.



Landfill









Landfill operation in Hawaii.





Disposing of waste in a landfill involves burying the waste, and this remains a

common practice in most countries. Landfills were often established in

abandoned or unused quarries, mining voids or borrow pits. A properly

designed and well-managed landfill can be a hygienic and relatively

inexpensive method of disposing of waste materials. Older, poorly designed

or poorly managed landfills can create a number of adverse environmental

impacts such as wind-blown litter, attraction of vermin, and generation of

liquid leachate. Another common byproduct of landfills is gas (mostly



7

composed of methane and carbon dioxide), which is produced as organic

waste breaks down anaerobically. This gas can create odour problems, kill

surface vegetation, and is a greenhouse gas.



Design characteristics of a modern landfill include methods to contain

leachate such as clay or plastic lining material. Deposited waste is normally

compacted to increase its density and stability, and covered to prevent

attracting vermin (such as mice or rats). Many landfills also have landfill gas

extraction systems installed to extract the landfill gas. Gas is pumped out of

the landfill using perforated pipes and flared off or burnt in a gas engine to

generate electricity.



Incineration

Incineration 10is a disposal method in which solid organic wastes are subjected to

combustion so as to convert them into residue and gaseous products. This

method is useful for disposal of residue of both solid waste management and

solid residue from waste water management. This process reduces the

volumes of solid waste to 20 to 30 percent of the original volume.

Incineration and other high temperature waste treatment systems are

sometimes described as "thermal treatment". Incinerators convert waste

materials into heat, gas, steam and ash.



Incineration is carried out both on a small scale by individuals and on a large

scale by industry. It is used to dispose of solid, liquid and gaseous waste. It is

recognized as a practical method of disposing of certain hazardous waste11

materials (such as biological medical waste). Incineration is a controversial

method of waste disposal, due to issues such as emission of gaseous

pollutants12.



Incineration is common in countries such as Japan where land is more scarce, as

these facilities generally do not require as much area as landfills. Waste-to-

energy (WtE) or energy-from-waste (EfW) are broad terms for facilities that

burn waste in a furnace or boiler to generate heat, steam and/or electricity.

Combustion in an incinerator is not always perfect and there have been

concerns about micro-pollutants in gaseous emissions from incinerator

stacks. Particular concern has focused on some very persistent organics such

as dioxins, furans, PAHs,... which may be created within the incinerator and

afterwards in the incinerator plume which may have serious environmental

consequences in the area immediately around the incinerator. On the other

hand this method or the more benign anaerobic digestion produces heat that

can be used as energy.



Recycling

The popular meaning of „recycling‟ in most developed countries refers to the

widespread collection and reuse of everyday waste materials such as empty

beverage containers. These are collected and sorted into common types so

that the raw materials from which the items are made can be reprocessed

into new products. Material for recycling may be collected separately from

general waste using dedicated bins and collection vehicles, or sorted directly

from mixed waste streams.



The most common consumer products recycled include aluminum such as

beverage cans, copper such as wire, steel food and aerosol cans, old steel

furnishings or equipment (Heavy melting steel I and HMS II), HDPE and PET

bottles, glass bottles and jars, paperboard cartons, newspapers, magazines

and light paper, and corrugated fiberboard boxes.



PVC, LDPE, PP, and PS (see resin identification code) are also recyclable. These

items are usually composed of a single type of material, making them

relatively easy to recycle into new products. The recycling of complex

products (such as computers and electronic equipment) is more difficult, due

to the additional dismantling and separation required.

Sustainability

The management of waste is a key component in a business' ability to

maintaining ISO14001 accreditation. Companies are encouraged to improve

their environmental efficiencies each year. One way to do this is by improving

a company‟s waste management with a new recycling service. (such as

recycling: glass, food waste, paper and cardboard, plastic bottles etc.)



Biological reprocessing

Waste materials that are organic in nature, such as plant material, food scraps,

and paper products, can be recycled using biological composting and

digestion processes to decompose the organic matter. The resulting organic

material is then recycled as mulch or compost for agricultural or landscaping

purposes. In addition, waste gas from the process (such as methane) can be

captured and used for generating electricity and heat (CHP/cogeneration)

maximising efficiencies. The intention of biological processing in waste

management is to control and accelerate the natural process of

decomposition of organic matter.



There is a large variety of composting and digestion methods and technologies

varying in complexity from simple home compost heaps, to small town scale

batch digesters, industrial-scale enclosed-vessel digestion of mixed

domestic waste (see Mechanical biological treatment). Methods of biological

decomposition are differentiated as being aerobic or anaerobic methods,

though hybrids of the two methods also exist.



Anaerobic digestion of the organic fraction of MSW Municipal Solid Waste has

been found to be in a number of LCA analysis studies to be more

environmentally effective, than landfill, incineration or pyrolisis13. The

resulting biogas (methane) though must be used for cogeneration (electricity

and heat preferably on or close to the site of production) and can be used

with a little upgrading in gas combustion engines or turbines. With further

upgrading to synthetic natural gas it can be injected into the natural gas

network or further refined to hydrogen for use in stationary cogeneration fuel

cells. Its use in fuel cells eliminates the pollution from products of

combustion (SOx, NOx, pariculates, dioxin, furans, PAHs...).

An example of waste management through composting is the Green Bin Program

in Toronto, Canada, where Source Separated Organics (such as kitchen scraps

and plant cuttings) are collected in a dedicated container and then

composted.



Energy recovery

The energy content of waste products can be harnessed directly by using them

as a direct combustion 14fuel, or indirectly by processing them into another

type of fuel. Recycling through thermal treatment ranges from using waste as

a fuel source for cooking or heating, to anaerobic digestion and the use of

the gas fuel (for cooking or heating), to fuel for boilers to generate steam and

electricity in a turbine. Pyrolysis and gasification are two related forms of

thermal treatment where waste materials are heated to high temperatures

with limited oxygen availability. The process usually occurs in a sealed vessel

under high pressure. Pyrolysis of solid waste converts the material into solid,

liquid and gas products. The liquid and gas can be burnt to produce energy

or refined into other chenmical products (chemical refinery). The solid residue

(char) can be further refined into products such as activated carbon.

Gasification and advanced Plasma arc gasification are used to convert organic

materials directly into a synthetic gas (syngas) composed of carbon monoxide

and hydrogen. The gas is then burnt to produce electricity and steam. An

alternative to pyrolisis is high temperature and pressure supercritical water

decomposition (hydrothermal monophasic oxidation).



Avoidance and reduction methods

An important method of waste management is the prevention of waste material

being created, also known as waste reduction. Methods of avoidance include

reuse of second-hand products, repairing broken items instead of buying



14 verbranding





11

new, designing products to be refillable or reusable (such as cotton instead of

plastic shopping bags), encouraging consumers to avoid using disposable

products (such as disposable cutlery), removing any food/liquid remains from

cans, packaging, ... and designing products that use less material to achieve

the same purpose (for example, lightweighting of beverage cans).



5.2 OTHER THAN EUROPE



5.2.1 Domestic waste in India

Handling domestic waste is normally a municipal corporation responsibility and

Indian cities have limited resources for proper collection, transport and

disposal. Even in Delhi. onIy. 60% of the homes are connected to sewers and

only 70% of sewage water15 is treated. There is a nonpoint pollution problem

for unsewered areas, and a point pollution problem for the waste

concentrated by sewers. Much of the treatment is totally inadequate. More

than half of the country's cities have no sewers. It is estimated that 65% of

water pollution is from domestic sources. Though domestic solid waste is

efficiently picked over by various informal sector operators.

Imog has a lot activities, such as recycling, empty the containerparks,

incineration, green composting, sorting of coarse dirt and wood waste.









6.2 INTERNATIONAL



6.2.1 Waste Recycling Group Limited

Waste Recycling Group Limited (WRG), a leading UK waste management and

energy recovery company, is part of FCC the international environmental

services, infrastructure and energy group.





WRG is focused on delivering integrated waste management and energy

recovery solutions to meet national, regional and local needs for local

authorities and private commercial companies. The Company operates

facilities for the reception, recycling and disposal of waste, including a

network of waste transfer and recycling centres and a regional network of

landfill sites, and also manages a wide range of recycling sites on behalf of

local authorities for use by the general public.









7.Personal opinion:





We think that domestic waste is a serious problem that we need to handle better

in the future. Not only we need to change our ways of handeling with

domestic waste but the governments need to change too. Here in Europe we

are making progress but in Asia or Africa they aren‟t. It‟s even that bad the

people in Africa use the garbage of Europe and America to make their

houses. If we don‟t change our way of handeling with garbage then it won‟t

take long untill we will feel the consequences of it.



13

The main thought of all this domestic waste is that we all have to stop it from

taking over our world.
