Management of Urban Waste

garbageThe questions relating to the management of urban waste and, by extension planning and management of the urban environment, are among the most complex to which environmental managers must respond because of their effects on human health, development sustainable.

The same source underlines that today the cities of developing countries in general, and those of Africa in particular are among the cities where the issue of environmental management is relevant. One of the biggest challenges facing urban authorities is the collection of household waste. These difficulties are reflected in an accumulation of household waste, the creation of numerous illegal deposits and the stagnation of waste and rainwater in many neighborhoods.

The city of Kinshasa, capital of the Democratic Republic of Congo is not spared from this situation. This city has experienced a population explosion in recent decades. Currently, the city has an estimated ten million inhabitants, but in 1980 it had only 2,400,000 inhabitants. This situation is mainly due to the rural exodus, which has aggravated the waste problems already existing in the city. In Kinshasa, waste management in general and that of household waste in particular represents a major and crucial problem. Formerly the city of Kinshasa was known under the name of Kinshasa the beautiful but, following the growing insalubrity, from now on, it is nicknamed Kinshasa the dustbin.

Furthermore, the absence of functional structures for the collection and disposal of household waste in the city leads to wild and uncontrolled dumping in the streets and in the waterways of Kinshasa. The municipality of Masina, one of the most populous municipalities in the city of Kinshasa deserves special attention. Indeed the municipality of Masina faces this same problem. Households in Masina throw garbage in inappropriate places, on the streets, along rivers, in rivers. Thus we are witnessing more and more creations of wild dumps in this part of the city.

All of these pre-discussed factors lead to a deterioration in the living environment of populations. The key question to which this post answers is based on the major problems linked to the management of household waste in the city of Kinshasa and more particularly in the commune of Masina;

  • the bad management of household refuse finds its origin not only in the absence of garbage cans and public dumps but also in irresponsible behavior of the population
  • without a real commitment from the competent authority to raise awareness and encourage the population to become aware of the state of degradation and pollution could lead to a state of disruption of the environmental balance
  • the recovery of household garbage can constitute the lasting solution in the sanitation of the city of Kinshasa

Generally, waste means any product that its owner abandons, such as old clothing, construction waste, used cars, drugs whose use date has expired, food debris from the kitchen, etc. Educating the population with better junk removal solutions and waste management techniques is the first step in solving the issue, which leads to excess local pollution.

The notion of waste can be approached in several ways. It varies from one author to another, from one country to another. This is particularly the case during changes it may undergo (collection, sorting, primary processing) and which gives it different physical, chemical and mechanical characteristics which gives it economic and ecological value.

Urban compost is a fermented mixture of organic and mineral residues generally obtained from household waste and used for the improvement of agricultural land. The compost is obtained by biological treatment of organic matter by aerobic fermentation.


Omega 3 Fish Oil Benefits

In recent years, Fish Oil capsules as a supplement have garnered more and more attention. Many regard this product as a miracle substance, and in many ways it is. The most beneficial part of the fish oil is the omega 3 fatty acids that are found in it.

In many Western countries, such as the U.S., many people are deficient in these essential fats, mostly due to the diet of Westerners. Sea food – fatty fish in particular – are not a staple of the Western diet. Compared to other countries, particularly in Asia where seafood is a staple of the diet, the U.S. has higher rates of heart disease. Since then, a myriad of health benefits have been linked to consuming this supplement.

What Exactly Are Omega 3 Fatty Acids?

Omega 3 fatty acids contain two substances that are important to the body but that cannot be produced internally, two acids called docosahexaenoic acid and eicosapentaenoic acid, or DHA and EPA, respectively. These two substances are much more present in Asiatic societies than they are in Western societies, and it is believe that this is a large factor in contributing to the lesser risk of heart disease in Asian populations. But Omega 3’s have much more health benefits than just that of the heart.

Omega 3’s have been linked to healthier skin, joints, brain, heart, and can even help increase your vision. It lowers bad cholesterol, and can even increase fertility. It also helps anti-aging and acts as an anti-inflammatory agent. A daily dose of Omega 3’s benefits all of this by:

Maintaining our eyes: The retinas in our eyes are covered by a soft layer of membranes. If these membranes are deficient in DHA, the process that converts light energy into the data that travels into our brain is slowed.

Keeps the heart pumping: It seems like Omega 3’s and the human heart were made for each other. They reduce triglycerides, stabilizes heartbeats, keep platelets in the blood from clumping together, and can even lower blood pressure.

Clears your skin: The acids helps contribute to clear skin, especially in the absence of sugar.

Reduces Cholesterol: Increases good cholesterol (HDL) and helps to keep arteries clear.

Boosts the brain: Keeping your arteries directly contributes to increased blood flow to the brain. Omega 3s have also been linked to reducing depression by altering neurotransmitters, and have even been used successfully in treating ADHD.

Increases fertility: This happens in both males and females by improving the sperm’s swimming abilities and by creating an ideal environment for the eggs implantation.

What to Look For in Fish Oil Supplements

With all these incredible benefits coming from just one substance, it’s no wonder that fish oil has gotten such a large amount of attention lately! By now you have probably made up your mind to go out and get some. Please do! But there are some things that you need to keep in mind while looking for a supplement.

First, fish oils supplements vary in the amount of DHA and EPA they contain. Some fish oil, such as salmon oil, naturally contains more DHA than EPA. Krill oil contains large amounts of both. Be sure you read the labels so that you know what you are buying before you make the purchase.

Can I Increase Omega 3’s Without Supplements?

The best fish includes wild caught (always wild caught) salmon or tuna, though it is present in just about every fish. You can also receive Omega 3’s from other fatty foods such as avocados, walnuts and almonds, and even olive oil.
