Disadvantages of recycling plastics

Keywords: plastics recycling, plastic packaging, environmental impacts, waste management, chemical recycling, energy recovery 1. Consumption of plastics and waste generation by sector in the UK in Waste Watch The project will see the construction of four 4 recycling plants in four regional capitals namely Accra, Kumasi, Sunyani and Wa. Gas rich in carbon monoxide and steam is recovered and used as fuel for power generation. It is for this reason that this company humbly submits this proposal on the Recycling of Plastic Waste. Recycling is one of the most important actions currently available to reduce these impacts and represents one of the most dynamic areas in the plastics industry today. And the latter is not also desirable since plastic is non-degradable. Country Power generation No. The supply of oxygen is limited, which means that much of the plastics turn into hydrocarbon, carbon monoxide and water. The recycling success would depend on a good collaboration between ESARB and the various Metropolitan Assemblies, Ministry of Environment and National Resources and other stakeholders in the sanitation sector. However, very little has been yet done in this area. However, the Plastic Waste component of Solid Waste poses a lot of problem in the Ghanaian environment because it is non-biodegradable and therefore can stay in the environment for a considerable length of time causing all sorts of problems. This indicates a historical growth rate of about 9 per cent p. One common technique is radical polymerization, which typically involves compressing the reactants to about a thousand times atmospheric pressure and heating them to degrees Celsius or above.

These bags now constitute a major proportion of the plastic waste generated throughout the country. This is the more reason why this project will be first aimed at these two metropolises before rolling out to the other regions.

challenges of recycling plastic

Today, 80 percent of Americans have easy access to a plastics recycling program, whether they participate in a municipal curbside program or live near a drop-off site. East 8, 1,, 87 U.

The gasification process involves heating plastics and adding a supply of oxygen and steam. This will also attract itinerant waste buyers to start moving from house to house to buy plastic waste.

Recycling of packaging materials has seen rapid expansion over the last decades in a number of countries. However, very little has been yet done in this area. If plastic products contain metal or glass, these are recovered as non-combustible matter. Gasification with melting furnace waste power generation first converts waste to gas at a high temperature then uses the emitted pyrolysis gas and char as fuel to turn a steam turbine and generate power. Recycling one ton of plastic saves 7. How plastics are sorted 20 21 Related Papers. The plastic wastes have virtually choked the drainage system in the urban centers of the country to such an extent that it takes only the slightest of rainfall to precipitate floods in major cities like Accra, Kumasi and Takoradi. This synthetic gas can be used as a raw material in the chemical industry to produce chemicals such as hydrogen, methanol, ammonia and acetic acid. This widespread replacement of the modes of packaging with plastics is an indication of the uniqueness of plastic properties such as versatility, inertness and flexibility, especially in the application areas of packaging. Thermal conversion pyrolysis equipment 6. ESARB Company Limited is locally registered by young professionals who are experts in various engineering disciplines.

Funding is anticipated from the Ghana Marketing Platform. The project as a matter of urgency will start from the southern sector of the country where the menace is very critical before subsequently rolling out to the northern sector.

Plastic recycling thesis

Yours faithfully ………………………………. Thermal recycling encompasses liquefaction, gasification and solid fuel. Advances in technologies and systems for the collection, sorting and reprocessing of recyclable plastics are creating new opportunities for recycling, and with the combined actions of the public, industry and governments it may be possible to divert the majority of plastic waste from landfills to recycling over the next decades. Monitoring of the processes from the collection of plastic waste to the recycling in new product will be carried out to ensure that there is a smooth process. The table below shows some countries that generate power from plastic waste and the capacity that each country generates. The project as a matter of urgency will start from the southern sector of the country where the menace is very critical before subsequently rolling out to the northern sector. Gasification with reformer furnace power generation subjects the waste to pyrolysis, and then adds oxygen to the resulting gas, carbonized solids, tar and other substances. The granulated blast furnace slag also produced is used in civil engineering and construction materials. While plastics have been recycled since the s, the quantities that are recycled vary geographically, according to plastic type and application. The Company takes great pleasure in presenting this proposal for the recycling of plastic waste to produce power for supply to industries and for domestic consumption in Ghana. Ahafo 39, 2,, 58 1,, 46 1,, 31 Northern 70, 2,, 35 1,, 26 1,, 17 U. Daniel Ansong Siaw Quantity Surveyor. The Thermal Recycling process 16 6. Abstract Plastics are inexpensive, lightweight and durable materials, which can readily be moulded into a variety of products that find use in a wide range of applications. Unfortunately, they're so durable that they break down very slowly in a landfill When plastics find their way into the environment -- into the ocean, for example -- they can break down more quickly, but they still take a long time to biodegrade; a plastic bottle may take a century to break down, for example, while a plastic beverage holder could take four centuries.

The recycling success would depend on a good collaboration between ESARB and the various Metropolitan Assemblies, Ministry of Environment and National Resources and other stakeholders in the sanitation sector. The various modes of solid waste disposal by these districts are shown in Table 1 see appendix.

In addition, because of the durability of the polymers involved, substantial quantities of discarded end-of-life plastics are accumulating as debris in landfills and in natural habitats worldwide.
