Chapter
1. The history of the
development of household waste disposal technology.
The
environment has always been a source of resources for mankind, but for a long
time its life activity did not have a noticeable effect on nature. Only from
the end of the last century, under the influence of economic activity,
noticeable changes in the Earth's biosphere began to occur. Currently, they
have reached alarming proportions. The rapid growth of population and the level
of consumption of natural resources, the modern pace of material production
lead to thoughtless handling of nature. With this attitude, a huge part of the
resources taken from nature is returned to it in the form of waste that is
harmful and unsuitable for further use.
App.1. (Types of waste
according to their state of aggregation)
Scientists estimate that 5 tons of garbage are generated daily in
the world, while its amount increases annually by 3% in volume. The
accumulation of household waste on the surface harms the environment, polluting
water, soil and the atmosphere and jeopardizes the possibility of the existence
of all life on the planet as a whole.
5
Therefore, one of the important issues around the world is the
disposal of household waste.
App.1.1. (Domestic and industrial waste disposal)
So,
today the main emphasis in the civilized world is not on the destruction or
disposal of waste, but on the possibility of their reuse through recycling.
This is called recycling.
App. 1.2. (Recycling process)
6
During
recycling, waste is returned to the process of technogenesis. Two
options for recycling waste are possible:
1.
Reuse of waste for its intended purpose after appropriate safe handling and
labeling. For example, the reuse of glass and plastic containers.
2.
Return of waste after processing to the production cycle. For example, tin
containers - in the production of steel, waste paper - in the production of
paper and cardboard.
Some
types of waste that cannot be used for their intended purpose can be recycled,
after which it is more expedient to return them to the production cycle as
secondary raw materials. So, part of the waste can be used to produce heat and
electricity.
Scientists
believe that almost all waste is subject to recycling, just some are more
effective in this, some less. So, if you recycle paper, you can save forests;
By processing organic waste, you can obtain effective fertilizer and increase
productivity, and the processing of scrap aluminum can save an incredible
amount of energy. Waste recycling allows you to save natural resources, reduce
the cost of mining, not harm nature and at the same time save, getting cheaper
raw materials. Full benefit! European countries today are actively investing in
recycling technology, Russia has yet to take major steps in this direction.
1.1.
Overview of household and industrial waste disposal techniques waste
Classification
Household
waste can be classified according to several criteria.So,
according to the composition, household waste is conditionally divided into
biological residues and non-biological waste (garbage).Biological residues -
food, wood, leather and bone. These types of waste quickly and completely
decompose and do not pose a great danger. Food waste is the biggest nuisance of
them.
7
When
they decompose, carbon dioxide and water are formed, but a large number of
dangerous microorganisms, parasites and carriers of infectious diseases are
also collected.
App.1.3. (Estimated
decomposition rates)
Non-biological waste includes: paper,
plastic, metal, textile, glass, rubber. The decomposition process of this waste
can last about 2-3 years and in most cases is accompanied by the release of
toxic substances that harm the environment and humans. According
to the state of aggregation, the waste is divided into: solid, liquid, gaseous,
pastes, gels, suspensions, emulsions.
Waste disposal methods:
- burial at the landfill (the most common way),
-burning,
-sorting and sending most types of waste for recycling
(waste paper, metal, glass, biowaste), recycling,
-aerobic biothermal composting.
Municipal solid waste (or MSW), as a rule, is a mixture
of biological waste and garbage - non-biological materials of various origins.
MSW are formed regularly as a result of the life of residents of houses.
8
Due to the heterogeneity of the waste, the discarded
solid waste can have almost any hazard class for the environment and people
from 1 to 5.
At the same time, non-hazardous waste is cardboard
and paper, other wood-based materials, glass-containing and textile waste. The
most dangerous household waste products are batteries, including batteries, as
well as broken electrical appliances, household chemicals, cosmetics and
antistatic agents, deodorants, pesticides - insect sprays.
Briquetting
is a new method of disposal of solid waste that is not yet widely used in
practice. It includes preliminary sorting and packing of homogeneous garbage
into separate briquettes, and then their storage in specially designated areas
(landfills).
App.1.4.(Waste briquetting)
The
garbage packaged in this way is compressed, which greatly facilitates its
transportation due to a significant reduction in volume.Briquetted garbage is
intended for further processing and possible use for industrial purposes. Along
with a method such as the processing of municipal solid waste, briquetting can
be transported for disposal or disposal by heat treatment.
In fact, this method is similar to the burial method, but in practice it has
several advantages over it. The disadvantages of the method are that the
heterogeneity of the waste generated and the preliminary strong pollution in
the
9
garbage
containers and the change in some components of the waste creates a greater
complexity of briquetting.
Since these methods of processing waste have a number of
drawbacks, despite their cheapness, the best option would be to completely
dispose of the garbage during its processing into secondary materials and fuel,
as well as its possible reuse.
Waste disposal.
When disposing of garbage (the Latin root utilis is useful), the
waste can be used for various purposes.Waste to be disposed of includes: all
types of metals, glass, polymers, yarn and fabric products, paper, rubber,
organic household and agricultural waste.The most efficient disposal method
today is the recycling of waste - recycling.
Thermal recycling.
Thermal processing refers to several methods:The simple waste
incineration method is the most common and one of the cheapest methods of waste
management. It is during burning that large volumes of garbage are utilized,
and the ash formed takes up less space, does not undergo decay processes and
does not emit harmful gases into the atmosphere. It is non-toxic and does not
require specially equipped burial sites.
Today there are several promising areas in recycling:
- a mechanical processing method in which the waste is
crushed and becomes, for example, an effective filler in construction.
-pyrolysis - the so-called oxygen-free combustion, in which there is no
combustion process. This recycling technology involves the creation of
conditions for the rapid decomposition of waste into simple substances in
special tanks, as a result of which the number of hazardous decomposition
products is reduced by several times.
10
- plasma processing (high temperature pyrolysis).This is a technological
process of gasification of garbage that occurs at a melting temperature higher
than in a conventional processing plant (above 900 ° C).
The main advantage of this method is that it allows you to successfully
solve the problem of environmentally friendly disposal of garbage without
unnecessary costs for preliminary preparation, sorting, drying.
In addition, there is such a method of waste disposal as composting.
Since most of the waste is made up of various organic residues, they are
susceptible to rapid decay in the natural environment.The composting method
is based on this property of organic substances. In the composting process,
there is not only disposal of a huge part of the garbage polluting the
environment, but also in the process it produces substances useful for
agriculture - fertilizers.
The presented methods of waste disposal allow recycling with the
least negative impact on the environment.
11
Chapter 2. Problems
of disposal of household and industrial waste in Dagestan.
The Republic of Dagestan,
as well as for most regions of the Russian Federation, is characterized by
environmental problems such as the disposal of production and consumption
wastes, high levels of air pollution, pollution of water bodies by untreated
and insufficiently treated wastewater and solid waste, land degradation,
desertification, land growth anthropogenic impact on the biodiversity of the
region.
The existing system of
waste management for production and consumption in the Republic of Dagestan is
based mainly on their disposal at landfills or landfills, which leads to
pollution of surface and groundwater, atmospheric air, soil and environmental
damage.
With a total population
of about 3 million people, more than 850 thousand tons of waste is generated
annually in the republic, and more than 300 hectares of land has already been
taken for storage (about 300 kg on average per person). Every year there is an
increase in waste generation. The annual excess of the mass of generated waste
over the ability to dispose of it amounts to about 530 thousand tons / year
(i.e. 45%) in terms of RD. These wastes form the annual flow that is
“distributed” to unauthorized landfills that spontaneously occur in the
territories of cities and regions of the republic.
The waste management
system formed at the municipal and regional levels is mainly focused on
ensuring environmental safety in the treatment of waste, and does not contain
incentives to reduce the volume of their disposal in the natural environment.
It is only possible to reduce the waste stream to landfills in one way,
large-scale and timely separation of recyclable components from municipal solid
waste. Annually,
valuable secondary material resources (waste paper, plastic, glass, etc.) are
exported to landfills and landfills of solid waste.
12
To date, according to our
data, the volume of waste processed into secondary material resources is more
than 32 thousand tons, or 2.8%, whereas in previous years this figure did not
reach 1%. The major parts of landfills do not comply with
environmental and sanitary requirements.
The extremely
unsatisfactory situation with the disposal of solid waste is developing in
rural settlements. The lack of funds for the creation of an organized system
for the collection and removal of waste in the territories of municipalities
leads to the emergence of unauthorized landfills in adjacent forests, fields,
ravines, along highways.
To date, out of 437
landfills for landfill, only 104 have municipal decrees on the allocation of
land for the construction of the landfill, the remaining 333 are unauthorized
landfills. Only 1 solid waste landfill operates in the republic with a design
capacity of 330 thousand tons / year (28% of the total amount of waste) located
in the city of Kizlyar, which has all the necessary regulatory documentation.The
problem of recycling industrial waste remains relevant. More than 220 thousand
tons of hazardous waste (five hazard classes; especially hazardous
mercury-containing waste, devices, mercury valves, thermometers, fluorescent
lamps, etc.), 265.5 tons of which have become unusable, have already been
accumulated in the territories of enterprises of various sectors of the
economy. In addition, there is a tendency to increase the proportion of mercury-containing
devices and waste fluorescent lamps that have fallen into disrepair (over 700
thousand pieces have accumulated in the administrative territories of the
Republic of Dagestan), electronic scrap (spent office equipment, electronic
household appliances and equipment) that are disposed of in landfills,
polluting and creating an additional burden on the environment.
The situation in the
collection, storage and disposal of medical and biological wastes is also
alarming.
13
The collection of
potentially hazardous medical and biological wastes is carried out together
with municipal solid waste, with their subsequent removal to landfills.
Another acute
environmental problem for the republic remains pollution of water bodies. The
volume of discharged contaminated wastewater in the Republic of Dagestan is
about 80 million cubic meters. This is the third result for the regions of the
North Caucasus Federal District (Stavropol Territory - 130.77, North
Ossetia-Alania - 106.5). Not a single wastewater treatment plant in the
Republic of Dagestan brings wastewater to a normally treated state. Today, USCs
operate only in the cities of Kizlyar, Khasavyurt, Makhachkala and Kaspiysk.
For these OSK reconstruction is required due to deterioration and low power.
The cities of Derbent, Dagestan Lights, Izberbash, Buinaksk, having no
treatment facilities, dump waste water without treatment.
Due to the active
economic impact on the water resources of the Republic of Dagestan in many
river basins, an unsatisfactory environmental situation has developed today,
especially in terms of the quality of surface water resources: the water of
many rivers and reservoirs is polluted with chemicals, heavy metal salts,
nutrients, pesticides, organic compounds . The largest economic burden is
experienced by such large river systems as the Terek, Sulak, Samur.
2.1.
Methods of processing and destruction of municipal solid waste in Dagestan.
There are various ways and options
for its destruction. So, the main way to dispose of solid waste is burial at
special sites (landfills).
At landfills, the destruction of
irretrievable waste occurs - the processing of household waste, as a result of
which they almost completely cease to exist as waste.
14
The disposal method is not suitable
for all types of solid waste, but only for non-combustible waste or for
substances that emit toxic substances during combustion.
The advantage of this method is that
it does not require significant financial costs and the availability of large tracts
of land. But there are drawbacks to using this method - it is the accumulation
of gas during underground rotting of waste. However, despite such a hopeless
situation in the republic, the government is taking effective measures to
combat garbage.
In Dagestan, work has begun on the
reception and processing of secondary raw materials. And if previously thrown
garbage remained in landfills and landfills, now there is every chance that it
will gain a second life. Enterprises are buying up recyclables to make a new
product out of it.
At
a glass factory in the Dagestan Lights only five hundred thousand units of
glass containers are produced per day. This is almost 180 million cans per
year. Broken glass is also launched into the production process. It is bought
from the population. At the same time, half of the glass containers produced
can be made from recycled materials, experts say. The figure is huge, it is 120
tons of cullet per day. Now the main task is to establish the reception of
recyclables.
App.2.(Production
and disposal of glass containers)
15
In
a year, the company will launch another production line. In this case, the
total volume of finished products will exceed 500 tons per day. This is 1
million bottles per day. The Ministry of Natural Resources has established
cooperation between the enterprise and regional operators. So that the glass
wastes are not sent to landfills, but recycled.
And
in Derbent, a plastic waste processing plant has been launched. A full
production cycle has been established: from the reception of recyclables to the
manufacture of finished products - granules. Then these granules are sent to
plants producing various plastic pipes. So far, the main supplier of
polyethylene is landfills. Also, plastic is additionally collected in markets
and at collection points. Moreover, the plant in the presence of more plastic waste
is able to increase production volumes.
In
total, the plant accepts more than six varieties of debris fractions. Here, on
the basis of the enterprise, plastic bags are already made from plastic waste.
Production will expand.In Derbent, a site is already being selected for the
placement of an eco-center for the reception of secondary raw materials. Waste
will be bought up from the population. There is also a process of arranging
container sites.To ensure separate garbage collection, this year alone more than
a thousand garbage cans will be purchased.
Gradually,
conditions for separate waste collection will be created in cities and regions.
These are equipped container sites and eco-points for recycling. But the most
important thing in this matter is the ecological culture of the population. And
rightly so, separately delivered waste will not remain buried at the landfill,
but will return to our everyday life as a new item.
16
The
first EcoPoint for the colection of household waste from the population was
opened in Makhachkala, not far from the Central Juma Mosque. Now residents of
the capital can sell their garbage to a regional operator, instead of throwing
it in a bucket.The opening ceremony was attended by members of the Government
of the republic, the leadership of the Ministry of Natural Resources of the
region, representatives of the spiritual administration, educational
institutions and ordinary citizens who did not come to EcoPoint empty-handed.
App. 2.1.( Reception
of household waste in Ecopoint)
Opening the event, Deputy Chairman of the
Government of the Republic of Abdulmuslim Abdulmuslimov noted that in recent
years, thanks to the systematic work carried out by the Minister of Natural
Resources and Ecology of Dagestan, Nabiyuli Karachayev, positive changes have
been outlined in the republic in ensuring environmental safety of the region.
2.2 Disposal of liquid waste in Dagestan.
Liquid waste, if storage and disposal
rules are not followed, can fall into the soil, into sewage, and cause
permanent damage to the environment, causing direct harm to living creatures in
the pollution zone. Failure to comply with liquid waste disposal regulations is
punishable by serious fines and may lead to the closure of an enterprise that
allows such serious violations.
17
Moreover, the companies themselves, whose
activity involves the generation of liquid waste, are often not able to dispose
of liquid waste in accordance with the law. After all, first of all for this
you need to have licenses. In addition, it requires deep knowledge, practical
experience, the availability of specialized machinery and equipment. It is for
these reasons that today the vast majority of companies do not independently
dispose of liquid waste, but outsource this work.
App 2.2.( The
issue of liquid waste)
In this vein, a company from Tatarstan intends to
implement a project in Dagestan to process liquid household waste into mineral
fertilizers.
The first garbage recycling plant in Dagestan is
planned to be built in Kizlyar. Austrian and German companies are ready to act
as investors in the construction, Kizlyar Mayor Alexander Shuvalov told TASS.
Local authorities expect that the construction of the
plant will help solve the problem of waste disposal in the entire northern part
of Dagestan (in addition to Kizlyar and Kizlyar district, it includes six
districts and two cities). In the future, it is planned that the garbage
processing plant will become the center of the Ecotechnological Park, which
will also include an electricity generation enterprise and a greenhouse
complex. In addition, as mentioned above, an earlier agreement was concluded
with a Russian-Italian company on the processing of
18
liquid waste with the subsequent production of mineral
fertilizers.The project will be implemented in the coming years.
According to the mayor of Kizlyar, the implementation
of the project of the waste recycling complex will solve a number of
accumulated problems, including garbage disposal in rural settlements of
neighboring regions. “Potential investors said they were ready to turn waste
into revenue. It is assumed that he [the plant] will process garbage from the
entire northern zone of Dagestan, which includes seven districts (Kizlyar,
Tarumovsky, Nogaysky, Babayurtovsky, Kazbekovsky, Novolaksky, Khasavyurtovsky),
as well as the cities - Kizlyar, Khasavyurt and Yuzhno-Sukhokumsk.
19
Practical part
Chapter 3. A business plan for
the collection, sorting and subsequent disposal of household and industrial
waste in the Republic of Dagestan.
Currently, there is a lot of talk
about the introduction of an environmental tax, but its mechanism has not yet
been worked out, and there will probably be a lot of opponents of such a law,
because it primarily concerns Sharks of a large and very profitable business.
But the formula is simple - whoever makes a profit must pay, because garbage is
a derivative of a certain production activity. In principle, the work was
delivered at large enterprises - the enterprise is involved in the disposal of
its own waste, but let's say trade.Receiving fabulous profits from the sale of
packaged goods, trade enterprises do not bear any responsibility for the disposal
of this very package, and the share of total garbage from it is very large.
Therefore, the issue of financing waste processing needs to be addressed
immediately while our planet is still alive!
I had an idea to
contribute to the solution of the problem of collection and disposal of
household waste in my own way. It’s probably not right to call this idea a
business plan, so we will call it “Volunteer project-skillful hands”.
This project will not require large cash injections,
and it is too early to expect profit, but the patience and perseverance of
like-minded people should bring results.
I had an idea, and what if we organize the production
of souvenirs and household goods from used product packaging. And we found
samples of souvenirs on the Internet, in a methodical manual (Author: Anna
Viktorovna Logunova; “From waste to income”; recycled crafts. ) The practice of
"waste to income" may be an idea for the development of a new
business. Finished raw materials will help significantly reduce the cost of
primary products and reduce the percentage of environmental pollution by
household waste.
20
App.3
(Plastic bottle products)
The implementation of this project would bring
enormous benefits if we begin to involve more and more participants
(schoolchildren, preschool children, children in boarding schools, students,
etc.). I propose creating youth movements in educational institutions that will
hold campaigns every year collecting recyclables in their settlements, creating
items suitable for farming and holding fairs under the motto “No more garbage
around us!”, and collecting the proceeds in your personal youth fund at
institutions, and then buying garbage banners on every street of the village,
and when promoting this project, additionally engage in landscaping the region.
In addition to fairs, you can hold contests for the best recycled item, not
only at the municipal, but also at the republican level. In my opinion, such
work will bring not only benefit and fun, but also fosters a sense of
responsibility and the need for respect for environmental problems in children.
App.3.1.(
Newspaper
& Plastic Bottle Products)
21
As my practice has shown, useful things can be made
from unnecessary things. These are interior details, toys, souvenirs, etc.
From plastic bottles you can make crafts for the
garden, kitchen garden, playground, as well as toys, souvenirs and much more.
From plastic covers you can make applications,
pictures, curtains, rugs, trays, decorate furniture, turn covers into lottos,
checkers and much more.
From disposable tableware you can make tulips or a
water lily, a frame for a picture or a clock, a wall panel or a fan, or a
colorful peacock ....
From cans you can make flower pots, stands for pencils
and pens, candle holders, toy furniture, trays for kitchen utensils and much
more.
From egg trays children’s toys, frames, lampshade for
the lamp, beautiful flowers are obtained.
It’s very easy to make a small table lamp from the
disks, the clock can be either desktop or wall, you can make pendants on the
walls or Christmas tree decorations. If there are many discs, original curtains
are made of them.
Applications, bookmarks for books, vases, handbags and
wallets - this is what each of us can make from wrappers from sweets.
Old pantyhose and socks make very cute dolls and funny
stuffed animals.
Studying the literature on the topic of our project,
we decided to try and craft our products from recycled materials. We made a fan
of plastic forks, a stand for pens and pencils from old damaged and scratched
discs, a needle bar and a casket for storing various jewelry.
The technology of separate collection of garbage will
somehow organize the marketing of the collected garbage, the money for the advertising
project will not be superfluous, but how much positive emotions will be
received, this contribution to the fight against garbage disposal will be
simply invaluable.
22
Conclusion
Many
sources of information were used in the work, thanks to which the necessary
methodological material was accumulated. When working on the project, I used
both traditional and Internet sources. I note that I was surprised by the
abundance of opportunities that anyone who wants to seriously address the
environmental problem in the form of processing and disposal of household waste
in the Republic of Dagestan is surprised. But waste recycling technologies
themselves are very expensive and require quite large initial financial
investments, and the enterprise itself requires monopolization of production.
Therefore, the responsibility for improving the situation in our republic, I
feel not only for the government (which take steps to create processing plants,
but also for people who should take better care of their locality, having
realized at least the fact that we are all believers, and purity is part of the
faith. To destroy the beauty that the Almighty bestowed upon us, I think this
is unfair to him. Participation of residents in frequent community work days,
conducting educational discussions with youth, creating youth movements
responsible for controlling the release and collection of garbage and their
subsequent involvement in “the Skillful Hands” project may not completely solve
the problem , but i’m sure that it will make a huge contribution to the disposal
of waste in our republic.
During
the implementation of an individual project, at the stage of developing a
business plan, I came to the conclusion that the search for an idea was a
complex process, internal work, imagination, and a dream. Finding an artistic
image is very difficult, not easy, sometimes painfully difficult. Any
interesting impression can give impetus, inspiration and insight. The desired
image can be found literally under your feet: in the pattern of fallen autumn
leaves, in bizarre lines of branches against a sunset, in the shape, pattern
and color of the stone.
23
It
is not necessary to fully transfer what was seen into the product, it is
enough, having pushed off from it, to develop an idea or image.
When
performing work from recycled materials, I presented myself with great
independence, scope for manifestation of creative initiative.
Performing
simple calculations on the economics of materials fosters frugality, teaches us
to analyze the economic efficiency of our work and save the family budget. And
the knowledge gained during the implementation of the project and the skills
during its design will be useful in further training and involving like-minded
people, because a whole life lies ahead! And only by joining together we can
change the world for the best!
