Interpretation:
The study has identified the obstacles to sustainable recovery and recycling of plastic solid waste which are technology, quality and demand, cost and capacity, market share and legislation and environmental concerns.
Concept Introduction:
The obstacles are slow upgrading of technology, limited number of machines, slow tooling sector, complicated mold design, bad trouble shooting in processing machine operations and requirement of variety of techniques.
There are also technical obstacles such as identification of sorting and collecting technology. The technical obstacles play major role in diminishing the recovery and recycling industries.
Answer to Problem 1CO
Solution:
The causes to obstacles in the recovery and recycling of plastic solid waste are analysed in terms of economic, environmental and social aspects of sustainability
Explanation of Solution
The causes to obstacles in the recovery and recycling of plastic solid waste in terms of economic, environmental and social aspects of sustainability are:
Economic aspects of sustainability include;
- Attractive export markets are at long distances.
- For recycled products there is relatively small local and regional markets.
- The level of export readiness is limited.
- The competition from imports is strong.
- The cost of input material is very high cost of input material.
- The cost of compliance is high.
- The cost of logistics is high.
- High labor cost.
- The capacity of collection is less.
- lack of producer responsibility.
- The research and development are limited.
- The technological upgrading has a slow pace.
- Manufacturing of limited machine.
- Weak tooling sector.
- Decrease in sorting facilities.
- Complexity in the mold design.
- Poor trouble shooting in operation of processing machine.
- Requirement of variety of techniques.
- The quality is determined by the price of the recycled material.
Scientific aspects of sustainability include:
- There is lack of certification to determine quality standards.
- There is lack of facilities required in quality testing.
- There is lack of plastic waste management in proper manner.
- There is lack of responsibility of the producer.
- Limited research and development.
- Low domestic demand for recycled products.
- The demand of high quality for recycled materials.
- Negative society image against the plastic industries.
The causes to obstacles in the recovery and recycling of plastic solid wastes are analysed in terms of in terms of economic, environmental and social aspects of sustainability.

- for the following transformations write the chemical equations and name the substances A, B, C, D as well as determine the type of reactionarrow_forwardWhat is the role of environmental chemistry in the development of sustainable technologies?arrow_forwardFrom the discussion question from Module 5, recall the chemical equation for the combustion of gasoline (iso-octane, C8H18) is: 2C8H18 + 25O2 ---> 16CO2 + 18H2O This means that 2 moles of iso-octane combine with 25 moles of CO2 to produce 16 moles of CO2 and 18 moles of water. This is important for understanding the impact of fossil fuel use on the atmosphere because burning one mole of fuel adds a lot of CO2. Thinking about this in terms of the stoichiometry, and change in concentration, suppose we had 1.0 mole of iso-octane dissolved in 1.0 m3 of atmosphere. That means the concentration of carbon-containing molecules would be 1 mole per cubic meter. However, ff we burned all that iso-octane and convert the C8H18 into CO2 the concentration of carbon-containing molecules increases. How much does the concentration of carbon-containing molecules increase if 1.0 mole of C8H18 in 1.0 m3 of air is converted into CO2 as shown in the chemical equation above?arrow_forward

- Refer to the attached photo. Thank you!arrow_forwardCoal-fired power plants emit CO2, which is one of the gases that is of concern with regard to global warming. A technique that power plants can adopt to keep most of the CO2 from entering the air is called CO2 capture and storage (CCS). If the incremental cost of the sequestration process is $0.019 per kilowatt-hour, what is the present worth of the extra cost over a 3-year period to a manufacturing plant that uses 100,000 kWh of power per month? The interest rate is 12% per year compounded quarterly.arrow_forwardThe citizens of the world burn the fossil fuel equivalent of 7 * 1012 kg of petroleum per year. Assume that all of this petroleum is in the form of octane (C8H18) and calculate how much CO2 (in kg) the world produces from fossil fuel combustion per year. (Hint: Begin by writing a balanced equation for the combustion of octane.) If the atmosphere currently contains approximately3 * 1015 kg of CO2, how long will it take for the world’s fossil fuel combustion to double the amount of atmospheric carbon dioxide?arrow_forward
