Importance of Recycling And Reusing Glass Bottles
One of the best methods to save environmental pollution is by recycling glass bottles and jars. Environment pollution is aggravated due to landfills and the problem is increasing day by day. Recycling and reusing of glass, plastic and other materials is among the best ways to reduce pollution and wastages. Bottles which are used can be recycled and reused effectively. Today there are many companies dedicated to the task of recycling and reusing these products for environmental benefits.
There are many advantages of recycling and reusing these bottles and jars. Some of the most important benefits include the following:

Save Energy: One of the best advantages of recycling these bottles is that it helps to save energy spent for manufacturing new bottles. The used bottles are crushed, melted and processed to manufacture new products. This helps to save considerable amount of energy in the form of oil and coal.
Environment Friendly: As old bottles are recycled, it requires less energy for manufacturing new bottles which in turn reduces the usage of raw materials and energy. Low consumption of energy indicates lesser pollution in the environment. By reducing the production of fresh glass, it is possible to reduce environmental pollution to a great extent.

Modern Technologies: The reuse of bottles is considered to be beneficial as there are many depots which utilize modern technologies to recycle the bottles in a cost effective way.


Save Landfill Space: By recycling bottles it is possible to reduce landfills. Today modern glass recycling depots focus on the recycling process to reduce landfills and thereby save the environment from pollution.

Pros and Cons of Recycling and Reusing:


However, most people prefer to reuse bottles instead of recycling it as recycling involves complicated process whereas reusing is quite easy. To reuse bottles, simple cleaning of the bottles is sufficient.

Moreover glasses of different colors can seldom be recycled together. It is important to recycle glasses of the same color together which can be quite a tedious task. The color of each bottle determines its chemical composition and different colored bottles include different chemical composition. Most often, there are separate collection bins for red, green and blue colored bottles.

But by reusing bottles for a large period of time reduces its strength and efficiency when it is used with carbonated drinks such as beer and soda. The strength of the bottles can be recovered by recycling it. With frequent use, bottles can deteriorate over time and therefore most people prefer recycling of bottles. Reusing bottles requires large amount of fresh water for cleaning processes. Bottles which are recycled also undergo various purification processes.

Today different depots function in different ways to recycle bottles. Various techniques and fuel efficiency methods are utilized by these companies to reduce pollution and recycle products.

Both recycling and reusing bottles have pros and cons which need to be considered while using glass bottles. Today there are various depots in different countries all over the world to recycle and reuse bottles.

Global warming: How poverty supports the most dangerous kind of emissions


The role of poverty in many aspects of life is a well-documented chronicle which stares the world in the face. Poverty has immense contribution to gender imbalance, abuse of rights, inability to access good food, water and healthcare amongst others.  This time, poverty has revealed that its tentacles are also in control of the transport and power systems in some of the third world countries especially experimenting ones of Africa. Nigeria is one or perhaps the only country in Africa housing over 15 million of various versions of 2-stroke engines. The Green Society of Nigeria has said that these messy and easily worn out engines are on every second of the day emitting partially combusted but very dangerous fuel gases to the ecosystem.

The global fight against depletion of the ozone layer aimed at protecting the biodiversity would not be complete if this menace described as ‘Asian Dilemma' by Anumita Roychowdhury, associate director of the Centre for Science and Environment (CSE) in India, is not addressed with immediate alacrity in all third world nations of Africa including Nigeria where these two and three wheeled engines predominate currently.

Nigeria has a totally collapsed power sector and cost of running bigger generators is not friendly to over 100 million pockets in Nigeria due to the fact that many are still living below the poverty line.  The introduction of ‘I pass my neighbor' was more or less like saying that a messiah had come. Most of them (that mainly come from China) cost as little as $55-$60 per unit.  

People choose these engines to get around and power their houses because they are cheap, powerful and easy to fix. But in the reverse, the environment and human health are compromised. And as cities balloon and populations grow, the number of journeys and two-stroke engines are bound to grow with it if uncontrolled.  All these toxic compounds contribute immensely to urban air pollution. There is urgent need to cut down on the usage of these engines but again, for this to be effective, the government must provide an alternative.

Some Countries Have Made Changes in this regard.  When Bangkok toughened up vehicle inspections and emissions standards in 2000, 2-wheelers were over 96% of the city's traffic. However, March 2004, released the result that only 40% was in use with 50% out of the streets, according to Supat Wangwongwatana, deputy director general of Thailand's Pollution Control Department.

African nations would need to also adopt what the Philippines did by offering interest free loan for operators of 2-stroke engines to upgrade to 4-stroke. This approach would appear most workable option as it is not easy to fix overnight their power and transportation systems. When 2-stroke baby taxis were phased out of Dhaka, Bangladesh, in 2002, particulate concentrations dropped up to 40%, with carbon monoxide as well as hydrocarbons fell significantly, S.M.A. Bari, director of engineering at the Bangladesh Road Transport Authority said.  

Let the whole world rise against the 2-stroke engines!

Environmental impacts of disposable diapers and sanitary towels


Much of what we buy and use are disposables. From medical and electronic waste to kitchen and dining products, the list goes on.  Throwaway products are usually made from paper, plastic and cotton, but plastic items are by far used the most.  Though some disposables can breakdown rapidly, others like throwaway diapers cannot.  Disposable diapers became commercially available forty years ago,  Mothers have continued to enjoy the convenience of using them. Similarly menstruating women when using disposable sanitary pads and tampons are at ease with the comfort and flexibility they offer.  But the negative impacts on the environment of using these disposal items are being questioned by environmental experts across the world.


Dr Emmanuel Iyayi is an environmental scientist. He stated that: ‘although the benefits of using these readily available products are no doubt useful, the environmental impacts that they give rise to are a real threat, mainly due to them being non-biodegradable and decaying into toxic waste over a period of time’. This creates many additional health hazards in such places as landfills, which can lead to both acute and chronic health effects.
 
Dr Iyayi commented that African scientists need additional resources and funding to support research and development to mitigate the risks of this very real issue.  ‘We need to develop alternative products that can be used by the population. These need to be low risk and environmentally friendly. Engaging manufacturers and suppliers at the early stages of development is essential to finding an environmental friendly solution to this very real environmental issue’

Hauwa Momoh is a geologist at the landfill site. She said the Waste management Authority is running an experimental project that utilizes the methane gas, a by product of the decaying material, in an attempt to generate electrical power. 

Environmental critics say that until our everyday culture changes and we start to cultivate an eco-friendly environment, we are jeopardising future generations’ environment,
