Solid Waste Management.


The 3Rs should be used to manage Solid Waste. https://www.nobedad.com/article/solid-waste-management/c=84941e57f5
Solid Waste is the waste which is in solid form. It can be divided into 5 different types; 
1. Medical Waste 
2. Electronic Waste
3. Sewage Sludge Waste
4. Industrial Waste
5. Domestic Waste

1. Medical Waste

 Biomedical waste may be of solid or liquid types and can be infectious. Examples of  biomedical waste include discarded blood, sharps, unwanted microbiological cultures and stocks, body parts (including those as a result of amputation), other human or animal tissue, used bandages and dressings, discarded gloves, other medical supplies that may have been in contact with blood and body fluids, and laboratory waste that exhibits the characteristics described above. Waste sharps include potentially contaminated used (and unused discarded) needles, scalpels, lancets and other devices capable of penetrating the skin.
Biomedical waste is generated from biological and medical sources and activities, such as the diagnosis, prevention, or treatment of diseases. Common generators (or producers) of biomedical waste include hospitals, health clinics, nursing homes, emergency services, medical research laboratories etc. The medical waste should be handled carefully with gloves and protective suits. It should not be thrown away in the open or in landfills. It should be burnt in high temperatures in incinerators. The ash should be disposed deep inside the landfills.
2. Electronic Waste

 Electronic waste or e-waste is described as discarded electrical or electronic waste. Used electronics which are destined for reuse, resale, salvage, recycling, or disposal are also considered e-waste. Informal processing of e-waste through burning and improper disposal in landfills in developing countries can lead to adverse human health effects and environmental pollution. Electronic scrap components, such as CPUs, contain potentially harmful materials such as lead, cadmium, beryllium, and brominated flame retardants. Recycling and disposal of E waste may involve significant risk to health of workers and communities in developed countries and great care must be taken to avoid unsafe exposure in recycling operations and leaking of materials such as heavy metals from landfills and incinerator  ashes.    E-waste should be recycled and should be disposed of properly. 

3.Sludge or Sewage Solid Waste

Sludge is a semi-solid slurry that can be produced from a range of industrial processes, from water treatment, waste water treatment or on-site sanitation systems. For example, it can be produced as a settled suspension obtained from conventional drinking water treatment, as sewage waste from wastewater treatment processes or as fecal sludge from pit latrines and septic tanks. The term is also sometimes used as a generic term for solids separated from suspension in a liquid; this 'soupy' material usually contains significant quantities of 'interstitial' water (between the solid particles).
Sludge should be converted into Bio Fuel or Bio Gas. Sludge can be given to farmers as manure. 

4. Industrial Waste

Industrial waste is the waste produced by industrial activity which includes any material that is rendered useless during a manufacturing process such as that of factories, industries, mills, and mining operations. It has existed since the start of the Industrial Revolution. Some examples of industrial wastes are chemical solvents, pigments, sludge, metals, ash, paints, sandpaper, paper and plastic products, industrial by-products and radioactive waste. Of this radioactive waste is the most dangerous as the radiation from the radioactive waste will be active for several hundred years (half-life) and damage the environment around it. Radioactive waste is disposed in special containers and these are buried in deep underground shielded bunkers. 

5. Domestic Waste

Domestic solid waste  commonly known as trash or garbage in the United States' and rubbish in Britain is a type of waste consisting of everyday items that are discarded by the public. "Garbage" can also refer specifically to food waste, as in a garbage disposal; the two are sometimes collected separately. It is segregated into Wet waste and Dry waste.  Wet waste is the vegetable waste.
Dry waste includes paper waste, plastic waste etc.
Recycling of Solid Waste -  The municipal solid waste industry has four components: recycling composting, disposals, and waste to energy via incineration. There is no single approach that can be applied to the management of all waste streams, therefore the Environmental Protection Agency, a U.S Federal agency, developed a hierarchy ranking strategy for municipal solid waste. The Waste Management is made up of four levels ordered from most preferred to least preferred methods based on their environmental soundness: Source reduction and reuse; recycling or composting; energy recovery treatment and disposal.


The 3Rs

 Reduce, Reuse and Recycle. These are the 3 most commonly used effective methods to reduce and manage the problem of solid waste generation and its proper disposal. Awareness also plays an important part. If everyone adopts the 3Rs, we will have a cleaner planet for our generations to come.
I have now explained what and how to manage different types of  solid waste in this article. Please comment and like this article.

    Solid waste management plays a vital role in maintaining the cleanliness of the city and we have to take care of it as throwing the waste on the road as equipment removal services cause several prone diseases like malaria, typhoid and increase the pesticides and make the environment unhealthy for the living.

The Journey to South Goa

  The Journey to South Goa We began this journey on the morning of 4th October 2019.  4th October 2019 (Friday) I got up at 4:30AM. I brushed my teeth and got ready. We kept the dental kit inside the bag. We wanted to start before 5AM because it takes around 11 hours to reach Goa by road from Bangalore by car if you go via the Chitradurga- Hubli highway. It was 10 minutes past 5 when the driver showed up at the our house. His name was Ramesh. He was suggested by one of my mother's friend Mr  Toms. He used to work in the hospitality industry. Then I was told to get into the front seat because my father wanted to sleep in the back seat because he had not slept enough the previous night. It was a white Toyota Etios. Then we started the car and drove towards the national highway. The road looked very quiet because it was 5 in the morning. It was drizzling in the morning and because of that it was a bit wet and cold. Then we drove quietly till 6AM. By then we had passe...

Covid-19 economic effects, China's rise, foreign policy and Indian Economy. Introduction I have been writing about my travel experiences all these days. But this one is different and my usual travel stories are not possible now due to covid-19. This post is about economics, diplomacy and covid 19. A different kind of a post. I will be discussing 4 topics in this post. They are economic effects of Covid on the world, China's rise as a global super power and its irresponsible  handling of covid, its aggressive foreign policy and then finally should India choose Capitalization over socialism.  Covid 19 Economic effects Fall in the GDP growth. This pandemic has just taught us how dependent we are on others and how dependent one country is on another country. The shutting down of industries and halting of farming activities have hit the global supply chain resulting in the deficiency of food supplies in many parts of the world. The recent US-China Trade war has resulted in the slow...

India's Foreign Policy

India's Foreign Policy Representative image only Introduction You would have already guessed what this blog is about. Yes, it is about India's Foreign Policy.  India is an emerging power and has the potential to become a superpower. Every country needs good allies to become a super power. India has a huge diplomatic outreach primarily due to its Diaspora. It has always taken a neutral stand during the cold war. India was heading the non aligned movement. Even though India was neutral, it was more dependent on the Soviet Union than the United States. Some of India's economic practices during the cold war era also resembled the policies of Soviet Government. India was very dependent on Soviet Union during the cold war era even though it was neutral.   India's Diplomatic Missions  India's diplomatic and foreign policy is handled by (MEA) Ministry of External Affairs.  Diplomatic missions of India India has diplomatic relations with almost all countries in the world...
