Plastic, especially single use plastics, is causing widespread damage to the natural environment

From the Arctic to Antarctica, Plastic is literally everywhere on the planet. In the United States alone, more than 100 billion plastic bags are used annually. The figure translates to more than 300 bags per person.  The UN estimates that between one and five trillion bags of plastics are produced worldwide. Since 1950, it is estimated that man has produced over 9.2 million metric tons of plastic. Of the plastic produced, 6.9 billion tons became waste and 6.3 billion tons was never recycled. That is, it ended in landfills. Nevertheless, the exact number of plastic bags produced globally is largely unknown.

The proliferation of the bags is high that it has overwhelmed most of the western nations waste collection systems. Part of the problems of the plastic bag is that the flimsy bags are among the least recycled products because they tend to jam machinery during recycling. Their lack of recyclability is one of the top reasons why plastic wastes are regarded as bad boys of pollution. Here are nine other reasons we have compiled:

1. Plastic is toxic and dangerous

Anyone who has ever burned plastic bags knows of its toxic smells. Just the smell of incinerated plastics can give you an idea of the toxicity of the substance. The chemicals in the plastic can be divided into three parts including the ingredients for manufacture, the by-products of manufacturing, and chemicals adsorbed by plastic. Some of the common harmful chemicals in plastics include Bisphenol A, Polyurethanes (PUR), polyacrylonitriles (PAN), and polyvinyl chlorides (PVC).  It has been established that the chemicals in plastics could disrupt hormones that are crucial for healthy existence. Additionally, plastics act as magnets for other range of poisons and pollutants.

2. Plastics are Forever

Forget diamonds! Plastics are truly forever as they are not biodegradable. This fact is emphasized by a shipping accident. In 1992, a shipping container with 28,000 plastic and rubber duckies fell somewhere between Hong Kong and the United States. To date, these duckies wash ashore from time to time. They have been spotted even in different oceans such as the eastern seaboard of the United States. To make it worse, that has not been the only plastic consignment lost in seas. There are millions of Lego pieces, sneakers, styrofoam insulation, plastic crates, and a plethora of other items lost in the sea. The lost consignment demonstrates how indestructible plastic is in the seas and the far-reaching effects of the pollution. Many scientists have claimed that it takes 1000 years for plastic to break down. 1000 years is a millennium by the way!

3. Groundwater pollution from plastics

Plastics are causing widespread pollution to the groundwater sources. Plastics usually reacts with water creating harmful chemicals such as Styrene Trimer and Bisphenol A which are extremely harmful to human health. Bisphenol A has been established to affect the reproduction system of a variety of animal species, and I wouldn’t be surprised if it has the same effects on humans. This point relates to the first point on the toxicity of plastics.

Plastic bags could block drainage
Floods are among the most common disasters caused by plastics in urban areas

4. Plastic cause floods

The major cause of floods is obviously heavy precipitation, usually from rainfall. However, there are some cases where the water damage and floods could be avoided if people had not been irresponsibly disposing of plastics. The dumped plastics often end up in canals, water reservoirs, and drainage. Eventually, they clog natural and artificial drainage systems thereby causing floods. Most towns and cities in the third world face flooding caused by drainage problems.

5. Plastic creates breeding grounds for mosquitoes

Related to the previous point, plastics prevent the flow of water creating pools that are perfect breeding grounds for mosquitoes. Malaria is a serious disease that is associated with a type of mosquito. Recent research has shown that mosquitoes feed on microplastics. As animals higher in the food chain feed on the mosquito, the microplastic is absorbed in their bodies.

6. Soil contamination could be attributed to plastics

The effects of plastic on soil are not as thoroughly studied as the effects of plastic on groundwater and marine contamination. Probably because the plastic on land is likely to find itself eventually in a water body. However, it is hypothesized that plastic on soil interferes with the normal development of plants and animals. China offers an interesting case study for studying the effect of plastic on soils as it has been using plastic materials in mulching since the 1970s.

7. Marine Pollution is perhaps the biggest effect of plastic

Basic geography informs us that the planet is majorly water, especially oceans and seas. As such, marine pollution has serious repercussions on the global geochemical cycles. The material can degrade to have disastrous consequences for marine life. A marine scientist from Plymouth University coined the term microplastic that refers to the microscopic fragments of plastics that are consumed by aquatic creatures.

Plastic bags are among the top five items found in beach and river cleanups. It is estimated that between 10 and 20 million tons of plastic find their way into the oceans and seas every year. The Independent reports that by 2050, there will be more plastic in the oceans than fish. Further, it is thought that 99% of all sea birds have consumed microplastics.

What is even more troubling is that the plastic would eventually be consumed by humans as food. The sea creatures consume the before mentioned microplastics, and some of the sea creatures are popular in human cuisine! In 2015 alone, 92.5 million tons of seafood was caught for human consumption.

8. Direct consumption of plastic kills animals too

It is estimated that 100 million marine life has died primarily because of plastic ingestion. Still, wild and domestic animals on land also eat plastic as they mistake it for food. When a considerable amount of plastic is stuck into an animals’ stomach, it prevents the animals from eating additional food. The sea turtle is notorious for mistaking plastic bags in the sea for jellyfish. Also, animals could get tangled and suffocate in plastic wastes.

9. Plastics contribute to climate change too!

The impacts of climate pollution do not end on interfering with plant and animal life. Plastics are also a major contributor to the problem of climate change. Greenhouse gases are emitted on each stage in the life cycle of plastic from its production, transportation, refining, and how it is handled as a waste product. By 2050, plastics alone could contribute up to 13% of the total greenhouse gases! 

Unlike climate change, there are no prominent deniers of plastic menace. Consequently, it should be relatively easy for mankind to reverse the global plastic pollution trend before the oceans turn to a big mass of plastic soup. The good thing is that some countries are taking action in implementing plastic bans and taxes. Nevertheless, more action is needed before we can irreversibly damage the planet.

Plastic bags were hailed as one of the marvelous inventions of the 20th century. Although the product was primarily invented in 1907 by Leo Baekelan, its widespread use occurred post World War II. Baekelan and other early inventors created plastic in small batches and the industrial production of polythene was in 1933 when a chemical plant in Northwich, England created it by accident. It was secretly used by the British military during World War 2. A Swedish company called Celloplast patented the polyethylene bag in 1965 by engineer Sten Gustaf Thulin.

It became even more popular in the 1970s in Europe and by 1980s most countries in the world had switched from the use of paper to plastic. By the mid-1990s, countries were appreciating the adverse environmental impacts of plastics. For instance, in 1997, a researcher discovered and reported the Great Pacific Garbage Patch that demonstrated how plastic was killing sea turtles as they mistook them for Jellyfish.

With the UN estimating that approximately 5 trillion bags of plastic are produced per year, plastics are often described as the number one consumer product in the world. But the plastic shopping bags are now emerging as one of the worlds’ most banned products because of their adverse environmental impacts. As of July 2018, the United Nations estimated that 127 nations have either implemented some sort of ban or tax for the bags. The bans are so widespread that even the terrorist group Al Qaeda joined in the banning. Strange world!

The European Union took steps to ban the bags as an effort to clean up the European beaches. The European Union targets that by 2025, plastic bottles should be made of recycled content and by 2029, 90% should be recycled.  In the United States, New York followed the steps took by California to ban the bags. Other states have mandatory recycling or reuse programs while at least 10 states have placed preemptive bans.  Reusethisbag presents a list of countries that have implemented some sort of restrictions

Countries in the third-world (such as Bangladesh, Cameroon, Burundi, Rwanda, Myanmar, Kenya and Nepal)are leading the world in banning plastic. More developed countries (e.g. Denmark, Sweden and the United Kingdom) tend to favor taxes in controlling the plastic menace. Many other countries favor partial bans or tax.

Countries are increasingly taking action against plastics

Bangladesh implemented a ban in 2002. Before the ban, there was a widespread fallacy that plastic bans and taxes would disproportionately harm poor nations and people who relied on the ‘free’ or inexpensive plastic paper bags to carry their belongings. As of April 2019, Africa led the bans with 34 countries implementing bans and taxes. 31 of the countries were in sub-Saharan Africa, among the world’s poorest regions. Kenya implemented a ban in 2017. Its ban is among the most punitive with violators facing up to 4 years in prisons and/or US$ 38,000 in fines for using or distributing plastics.

Generally, the bans have proven to be a success in reducing the number of plastic wastes generated. For instance, Denmark passed the first plastic bag tax in 1993 and on average, a person uses four plastic bags a year. In contrast, a person in the United States uses 300 bags a year.

The bans of plastic bags often spawn to the bans of other products such as plates, cups, cutlery, straws, and bottles. Single-use plastics account to 40% of the plastics manufactured on the global scale.

Despite the numerous bans on the product, plastic bags are still ubiquitous in many parts of the world. Part of the reason for the limited success of the bans is the political opposition to the bans. Additionally, the WRI (2018) report that over 90% of the countries implementing bans favored partial over total bans. Partial bans have various exceptions on thicknesses and usability. For instance, In Kenya, companies can use plastic bags to package their products as long as they label them.

At Silvica, we believe that responsible consumer behavior is key in addressing the issues of plastic menace. If consumers are to increasingly shun plastic packaged products, the industry will be forced to comply. But, the issue is not as easy as that. Plastic is probably the cheapest form of packaging and consumers will often prefer cheaper products. Talk of conundrums!

On the 28th August 2017, the then Cabinet Secretary of Environment and Natural Resources, Professor Judy Wakhungu, banned the use, manufacture, and importation of plastic bags used for commercial and household packaging through the Gazette Notice number 2334 and 2356. Kenya followed the footsteps of countries such as Denmark, Bangladesh, and Rwanda that had implemented a plastic ban. And, its penalties are among the harshest in the world.

The ban affected all plastic secondary package carrier bags notwithstanding their thickness or color. Nevertheless, flat plastic bags for industrial primary packaging were exempt from the ban as long as they were not available for sale outside the industrial setting and they should be printed with the name of the company and the product. Also, the ban did not affect plastic sheets for construction and greenhouses, cling films, and adhesive tapes.

Plastics are known to cause a myriad of environmental problems.

Plastic pollution is a problem

Plastic pollution have diverse negative effects that range from climate change to animal health. Bans on plastics go a long way in addressing some of the effects of plastics

Plastic must be the bad boy of pollution

The primary purpose of the ban was to reduce plastic pollution in the country. Although the convenience of plastic bags is virtually unmatched, it also brings extraordinary environmental problems. For instance, the material doesn’t biodegrade and would most likely end up in the ocean leading to devastating consequence to the marine life.

In theory, some of the plastic wastes could be recycled. However, only 1-3% of plastic is recycled in practice. The rest of the plastic is ubiquitous in landfills, oceans and the streets. The pollution is not only present at the disposal stage as its production process is also a concern. Plastic production uses up to 8% of global oil resources.

Kenya banned plastic because of the environmental problems associated with it. The plastic bags were, and are still an eyesore, in some of the major towns in Kenya. The eyesore was also present in some of Kenya’s unrivaled natural heritage sites such as the beautiful Masai Mara.  For the residents of cities such as Nairobi, plastic bags were a major contributor to the blockage of drainages leading to flooding. Numerous reports have also shown that plastic bags were eaten by livestock and wildlife to their detriment. Moreover, they also presented public health risks as reusing plastic is a hotbed for pathogens.

The decision to ban plastic in Kenya was certainly welcome by a variety of stakeholders including environmentalists and public health professionals.

The imperfect ban

The common saying half a loaf of bread is better than no bread could apply to the plastic ban in Kenya. An imperfect ban would be better than no ban. The ban is imperfect because of two reasons. First, polypropylene is still widely used in Kenya. Secondly, it is suspected that single-use plastic bags are making a comeback. Although they are still plastics, polypropylene reusable and are not as thin as the polythene bags that could be easily carried by the wind.

However, a more concerning issue is the observation of the re-emergence of plastic bags. The small colorless plastic bags are noticeable in most market areas of Kenya. Does this mean that the government is more relaxed about the plastic ban?

Supermarkets have complied with the ban in Kenya, but not the small scale traders

Businesses such as supermarkets have complied with the ban. Additionally, companies that used to manufacture the bags have stopped, and closed, or resorted to other businesses. Nevertheless, The EastAfrican reported in 2018 that the ‘banned’ plastic bags are back amongst small traders vending fruits, vegetables, milk, meat, and paraffin. However, the vendors rarely display the bags in public. Many choose to use the bags only for the customers they know and trust. New customers are often told to bring their own carrier bags.

The small traders claim that plastic bags are their ideal packaging material because of its convenience. The product is still cheap and is their preferred packaging material because of its hygienic and unbulky nature. Most of the traders claim that they are using plastic bags because they see their colleagues use them. The major fear that the traders have is that they may lose business to the traders who have the bags.

Ironically, the buyers claim that it is the traders fault. The EastAfrican report that one of the buyers’ claim, “I’m only buying goods, so I take them in whatever material they’re packed in.” It is difficult to assign blame, but we think the buyer should steal demand that the goods bought should be packed in ‘legal’ packaging. After all, the risks for using and distributing plastic bags in Kenya is up to 4 years in prison and fines that could range from $19,417 and $38,834.

Obviously, there are dealers who distribute the bags to traders as the bags are readily available in most parts of Kenya. The EastAfrican report that a pack of 200 flat bags used to retail at US$ 0.3 and 0.5, but it now costs at US$ 1.5. The trade of flat plastic bags must be a booming business!

It is suspected that most of the bags in Kenya emanate from Uganda. The Kenyan environmental czar, the National Environmental and Management Authority (NEMA) is aware of the mushrooming business of illegal plastic trade. It warns that users and distributors of illegal plastic risk severe punishment from the law.

At Silvica, we think the buyer has the greatest responsibility in ensuring that the plastic ban in Kenya is effective. Buyers should carry their own packaging materials when they are making purchases. They should insist on avoiding purchasing goods packaged in illegal plastic. Businesses are only responding to the demands of the buyer. After all, the plastic ban is beneficial to the small scale traders as it relieves them of the responsibility of packaging material for the products!
