Citarum River, Indonesia
The Citarum has been called the world's most polluted river. Around
five million people live in the river's basin, and most of them rely on its
flow for their water supply.

Yamuna River, India
The Yamuna is the largest tributary of the Ganges River. Where it flows
through Delhi, it's estimated that 58 percent of the city's waste gets
dumped straight into the river. Millions of Indians still rely on these murky,
sewage-filled waters for washing, waste disposal and drinking water.

The North Pacific Gyre
An island of trash twice the size of Texas floats in the middle of the Pacific
Ocean, circulated by the currents of the North Pacific Gyre. The trash,
which is mostly made up of plastic debris, floats as deep as 30 feet below
the surface.

Earth's orbit
Believe it or not, even space contains copious amounts of pollution. An
estimated 4 million pounds of space debris — nuts, bolts, metal and
carbon, even whole spacecraft — currently orbit the Earth, threatening
satellites, communication and even the lives of our astronauts.

Municipal Solid Waste (MSW)
The garbage we produce in our houses, offices, and
cities, accounts for a small percentage of total waste by
weight, but it is one of our most important challenges in
waste management. (R2/13)
The US data:
– EPA - each American produces
4 pounds of trash per day
– BioCycle magazine estimates
6.6 pounds per day.

Waste management
Currently, in the US:
•54 percent of waste is landfilled
•13 percent is incinerated,
•33 percent is recycled

Every day your waste is managed as discreetly as possible.
Different managing alternatives can be applied to it, depending
mainly on its characteristics. Between the most important waste
treatments, we can find sorting and recycling, composting,
energetic valorisation or landfilling.

Landfills
Waste that can neither be reused nor receive
special processing is stored in landfills.
Beforehand, some waste may need to be stabilized
to prevent pollution leakage.

Modern Sanitary Landfill
•Designed to contain waste.
•Compact the refuse
•Cover it every day with a layer of dirt to decrease smell
and litter and to discourage insect and rats.
•Helps control pollution
![Page 30: Pengetahuan Lingkungan Waste · 2015. 10. 11. · Sorting and 3R. Sorting and recycling allows the recovery of raw materials, which can be later used to manufacture new products.](https://reader033.fdocuments.net/reader033/viewer/2022053111/6083e2047fc1b10cc566f81b/html5/thumbnails/30.jpg)
Landfills has some drawbacks:
1. litter and ash can be scattered by the wind: trash
must be covered
2. organic wastes partially decompose under certain
conditions to produce carbon dioxide, methane,
ammonia, water, and other chemicals, which may
be released into the atmosphere.
![Page 31: Pengetahuan Lingkungan Waste · 2015. 10. 11. · Sorting and 3R. Sorting and recycling allows the recovery of raw materials, which can be later used to manufacture new products.](https://reader033.fdocuments.net/reader033/viewer/2022053111/6083e2047fc1b10cc566f81b/html5/thumbnails/31.jpg)
3. during decomposition, liquids may percolate
through the landfill and carry chemicals into
the soil and groundwater.
4. landfills contain many common items such as
glass, plastics, and metals that will never
biodegrade
![Page 32: Pengetahuan Lingkungan Waste · 2015. 10. 11. · Sorting and 3R. Sorting and recycling allows the recovery of raw materials, which can be later used to manufacture new products.](https://reader033.fdocuments.net/reader033/viewer/2022053111/6083e2047fc1b10cc566f81b/html5/thumbnails/32.jpg)
A landfill requires high technical standards and must
conform to strong safety norms in order to protect the
environment and local communities. It is very important
taking into account:
1. The location for the landfill and the
surrounding land
2. The design of modular compartments
3. The protection of groundwater
4. The collection, treatment and elimination of
leachates
5. The capture, treatment and recovery of biogas
6. The construction of a cover, in order to
minimize rainwater penetration

Over time, waste, which decomposes
produces landfill gas or biogas, a mixture
of carbon dioxide and methane.
Biogas is collected and then used in co-
generation processes, which produce
energy and heat, at the same time that it
is avoided the emission to the
atmosphere of methane, which is a
harmful green house gas.

Apart from biogas, the decomposition of landfilled waste, along
with rainwater infiltration, produces a liquid known as "leachate".
Leachates contain heavy metals, salts, nitrogenous compounds
and various types of organic matter. Due to its high polluting
potential it is needed that this leachate is collected and treated to
avoid environment contamination. Source: http://www.microphilox.com/reference_01.htm

Incineration
Incineration produces ash that includes minerals,
metals, unburned organic carbon, and dirt:
1. fly ash consists of light particles that contains
volatile metals such as mercury, lead, and
cadmium as well as dioxins and PCBs.
2. bottom ash consists of the uncombusted materials
remaining on the grate after burning.

Bottom ash usually contains:
less volatile metals such as aluminum, iron, and
tin as well as hydrocarbons
In some cases, this ash could be highly toxic,
because the heat of the incinerator may increase
the toxic properties of the materials burned.

Energy from waste
Nowadays, energy recovery goes hand-by-hand
with waste elimination. There are different ways of
getting energy from waste: incineration,
gasification, anaerobic digestion,….
Traditionally, the most used one has been
incineration, although the other treatments are
emerging technologies that are being quickly
extended.

Energy from waste
Refuse-derived fuel: refuse is sorted as it comes
in to remove unburnable or recyclable materials
before combustion.
Mass Burn: dump everything as much as possible.
Avoids expensive and unpleasant job of sorting but
produces more unburned ash and more air
pollution.

Three different kind of waste are accepted in an
incineration facility:
1. Household waste
2. Non-hazardous industrial waste
3. Rejects from sorting centres
Remove batteries containing heavy metals and plastics
containing chlorine before waste are burned.

Sorting and 3R
Sorting and recycling allows the recovery of raw materials,
which can be later used to manufacture new products.
Recycling: the reprocessing of discarded materials into
new products. (old aluminum cans and glass bottle –
new cans and bottles)
Recycling saves money, energy, and space.
First step to recycling is sorting or separation

Sorting and recycling
Two types of waste are accepted at the sorting centre:
1. Household waste: packaging (glass, plastic, aluminium,
cardboard and steel) as well as newpapers and
magazines
2. Commercial and industrial waste: card, paper, wood,
metal, plastic, building site waste

Once the waste arrives at the centre, it takes place
an initial pre-sorting and a first phase of mechanical
sorting.
After that, a manual process is applied and material
is separated in two different groups:
1. Reusable material
2. Non-recyclable material, which is normally sent
to incinerating facilities where it is recovered to
energy.

Reusable material is packed and sent either to recycling facilities
or they are supplied to industry for reuse (for example, card for
the paper industry, plastic for manufacturing piping, etc)

economic barriers of recycling:
1. manual separation is an expensive process,
but contamination makes an entire batch
worthless
2. large differences in the weight-to-volume ratio
may reduce incentives to recycle
3. there does not yet exist a consistent supply of
inputs or a consistent demand for recycled
products to stabilize prices.

Reuse
• Better than recycling
• Cleaning and reusing materials in their present
form
• Saving the cost and energy of remaking them
into something else
• Ex: glass and plastic
bottles are routinely
returned to beverage
producers for washing
and refilling.

Reducing
• Often the cheapest option
• The most important strategy in 3R
• Excessive packaging of food and consumer products is one of our greatest source of unnecessary waste.
• Photodegradable plastics break down when exposed to ultraviolet radiation.
• Biodegradable plastics incorporate such materials as cornstarch that microorganisms can decompose.

• ADa beberapa hal yang bisa banget nih kita lakukan..
Misalnya :
• Yuk Kita mengganti KULTUR PERANG AIR saat wisudaan, yang ternyata
satu himpunan saja bisa sampai 8000 plastik, dan membuang air bersih
begitu saja.
• Mari Kita TIDAK lagi MENGGUNAKAN STYROFOAM di setiap acara
yang kita bikin.
• Sudah saatnya kita membawa BOTOL MINUM dan TEMPAT MAKAN
SENDIRI untuk mengurangi pembelian botol plastik air kemasan, dan juga
bungkus plastik untuk makanan
• Dan tentu sudah saatnya pula kita mengurangi konsumsi Kantong KRESEK
dengan cara memakai kembali kantong kresek yang sudah kita simpan, atau
dengan membawa tas yang praktis dan dapat menjadi wadah pengganti
kantong kresek.
• Yuk kita Memilah sampah,cuma dua jenis ko, ga suliitt,,
• Ayo kita mengurangi publikasi dengan media kertas, karena kertas dari
pohon, dan deforestasi semakin meningkat di Indonesia. Ganti yuk dengan
media maya.sekarang lebih trend loh.. (bisa contoh tuh publikasi nya M-
FEST HMM, dan juga BIOFRONT nya NyMPHAEA..PAPER LESS banget loh
booooo..hehe

TPA Benowo Jadi Contoh Pengolahan Sampah Nasional
Sistem pengolahan sampah TPA Benowo menjadi listrik dan bahan baku bangunan
kedepannya mempunyai manfaat cukup besar.
"Kalau tidak salah nantinya air limbah yang selalu menjadi persoalan itu bisa diolah
menjadi air bersih," kata Tri Rismaharini, Jumat (13/6/2014).
Tidak ada sampah yang tersisa di TPA Benowo. Hasil olahan sampah kedepan bisa
mendatangkan manfaat bagi warga Surabaya.
Pengolahan sampah TPA Benowo penuh teknologi yang digunakan pertama kali di
Indonesia.
Pemilahan sampah yang bisa didaur ulang dan yang tidak bisa didaur ulang akan
dilakukan oleh tenaga manusia.
Di samping itu, ungkap Machmud, dengan teknologi yang digunakan dengan hasil nol
sampah tersebut menjadi jaminan tersendiri tidak akan dibutuhkannya lahan baru.
Pengolahan sampah sistem sanitasi lenfil, sampah hanya ditumpuk dan dipisahkan air
limbahnya yang lambat laun akan menghabiskan lahan TPA.

Composting
Composting: biological degradation or breakdown
of organic matter under aerobic (oxygen rich)
conditions.
Composting is a process that has always existed in
its natural state. Today, with modern technologies,
this process can be accelerated and monitored
efficiently.
It is an excellent way of regenerating soils
impoverished by intensive farming.
![Page 67: Pengetahuan Lingkungan Waste · 2015. 10. 11. · Sorting and 3R. Sorting and recycling allows the recovery of raw materials, which can be later used to manufacture new products.](https://reader033.fdocuments.net/reader033/viewer/2022053111/6083e2047fc1b10cc566f81b/html5/thumbnails/67.jpg)
Composting is a process based on the
decomposition of organic matter by
microorganisms in the presence of oxygen.
The result is a stable organic product, which is
both hygienic and rich in humus. This process,
which normally takes several months, can be
speeded up and controlled using various
techniques.
Once the composting process is finished a
product called compost is obtained, which is
mainly used for agriculture manure.
![Page 68: Pengetahuan Lingkungan Waste · 2015. 10. 11. · Sorting and 3R. Sorting and recycling allows the recovery of raw materials, which can be later used to manufacture new products.](https://reader033.fdocuments.net/reader033/viewer/2022053111/6083e2047fc1b10cc566f81b/html5/thumbnails/68.jpg)
Four types of waste are accepted in the
composting facilities:
1. Waste from the wood industry (bark, shavings),
the paper industry and the food industry.
2. Farming waste: manure, mineral fertilizers, etc.
3. Household waste (food, garden).
4. Sludge from the sewage plants.
Composting faces similar challenges to those of
recycling.
