It takes thousands of years for typical plastic and almost one year for biodegradable plastic for complete breakdown, but under favorable condition with proper sunlight (ultraviolet light) which breaks its long chain bonds and requires high pressure. Plastics from various sources like household items, trash contains low density polyethylene (LDPE), polyethylene - terephthalate (PET), polypropylene (PP) which under pyrolysis can be broken down into smaller number of carbon chain (alkanes) and can be converted to flammable oils which will burn with clean and non - sooty flame. Other method of converting them to fuel is by using some other materials which will help polymer chain to breakdown easily such as pyrolysis of plastics with low grade coal which is generally having low calorific value. Second option could be by combining polymers with low grade heavy Sulphur content oils which under certain temperature and pressure with some suitable catalyst which will infuse Sulphur from sour oil to long chains of polymers thus breaking them down. Talking about biodegradable plastic they can be converted to fuel by microalgae which will convert it to solid fuel upon treatment and certain bacteria which upon eating releases certain flammable gases and can be used as a biogas in biogas plant. This review aims on highlighting the various process for conversion of plastics to fuel.","PeriodicalId":243799,"journal":{"name":"EngRN: Energy Systems (Topic)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130671574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We develop a dynamic Cournot game featuring two risk-averse electricity producers – one hydro and one thermal – under demand uncertainty. We demonstrate that while improving air quality necessarily raises the market price, enhancing ecosystem integrity can, under the water-abundance hypothesis, reduce it. Moreover, in order to establish a statement about the environmental policy’s efficiency, we examine interactions between these environmental measures and their potential side effects. We show that prioritizing a natural flow regime minimizes the taxation efficiency of lowering air pollution and emphasizes the price rise due to taxation. Nevertheless, the effect of the taxation policy on the efficiency of the ecosystem integrity policy depends on the hydro producer’s ability to substitute thermal units. In order to establish a precise environmental statement, regulation authorities need to compare, using appropriate criteria, the importance of an avoided unit of surrounding ecosystem alteration with the importance of an avoided unit of air-polluting production in the functioning of the whole ecosystem.","PeriodicalId":243799,"journal":{"name":"EngRN: Energy Systems (Topic)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129568676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the processes of this kind the formation rate of the molecular addition products (1:1 adducts) as a function of concentration of the unsaturated component has a maximum. Five reaction schemes are suggested for this addition processes. The proposed schemes include the reaction competing with chain propagation reactions through a reactive free radical. The chain evolution stage in these schemes involves three or four types of free radicals. One of them is relatively low-reactive and inhibits the chain process by shortening of the kinetic chain length. Based on the suggested schemes, nine rate equations (containing one to three parameters to be determined directly) are deduced using quasi-steady-state treatment. These equations provide good fits for the nonmonotonic (peaking) dependences of the formation rates of the molecular products (1:1 adducts) on the concentration of the unsaturated component in binary systems consisting of a saturated component (hydrocarbon, alcohol, etc.) and an unsaturated component (alkene, allyl alcohol, formaldehyde, or dioxygen). The unsaturated compound in these systems is both a reactant and an autoinhibitor generating lowreactive free radicals. A similar kinetic description is applicable to the nonbranched-chain process of the free-radical hydrogen oxidation, in which the oxygen with the increase of its concentration begins to act as an oxidation autoingibitor (or an antioxidant). The energetics of the key radical-molecule reactions is considered.","PeriodicalId":243799,"journal":{"name":"EngRN: Energy Systems (Topic)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128355266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
