This study aims to analyze the influence of financial performance, quality audit, independent commissioner to the effective tax rate. By using a sample of 30 real estate & property company listed in Indonesia Stock Exchange in the year 2015 to 2018 the number of data 71 after deducting the data outlayer. The method used is multiple linear regression. The results of this analysis, the variable size of the company does not affect the effective tax rate, leverage does not affect the effective tax rate, profitability affect the effective tax rate, capital intensity ratio does not affect the effective tax rate, inventory capital ratio affect the effective tax rate, quality audit affect the effective tax rate, independent commissioner affect the effective tax rate. Based on the test of the coefficient of determination (R2) equal to 27.3% of the variable effective tax rate can be explained by the variable firm size, leverage, profitability, capital intensity ratio, inventory capital ratio, quality audits, independent commissioner while 72.7% are influenced by variables other.

“…It can also be described as the process of converting the energy value in solid fuel into chemical energy in gaseous fuel. It transforms solid fuel into hydrogen- and carbon monoxide syngas [ 47 ]. It is theoretically feasible to remove plastic waste using gasification in fluidized bed technology [ 48 ].…”

Combating the menace of plastic waste pollution has become a global environmental challenge. Plastic pollution is capable of affecting land, waterways and oceans as a large percentage of marine and land creatures have died due to the fact that plastic is non-biodegradable and it causes hazards to soil. It also emits toxic gasses when exposed or heated up. It blocks drainage lines and fill up land space causing floods and erosion thereby causing deterioration of the Nigerian roads. Plastics wastes are also harmful to human health; they may contain harmful acids which may lead to death. Nigeria, which is the biggest oil exporting country in Africa, relies mainly on the proceeds of the oil trade for its GDP and based strategy in growing her economy. However, with the declination of oil prices and increase in plastic wastes, the world is tending towards energy and sustainable development. Therefore, an urgent need for recycling plastic wastes into a solution for wealth creation is fundamental in Nigeria. This paper therefore seeks to identify favorable methods for recycling plastic wastes in Nigeria as a tool for solution to diversification and implementation. Evidence based examples are illustrated in the article with viable solution recommended for implementation.

“…Various authors have examined the gasification of plastics along with biomass, coal and other feedstocks for syngas and hydrogen production with varying degrees of success. [31][32][33][34][35][36][37][38] Xiao et al 31 examined the fluidized bed gasification of PP-based plastic wastes using air as the gasification medium. The study examined the parametric effects of the gasification parameters namely; equivalence ratio (ER), bed height (H) and fluidization velocity (μ f ) on the product distribution, gas yield, gas composition, and syngas heating value.…”

The article presents an overview of the status, challenges, and prospects of current and emerging trends for the sustainable treatment and valorisation technologies of plastic wastes. The proliferation is ascribed to the growing population, living standards, and use of low cost, unbiodegradable, and chemically resistant plastic wastes in Nigeria. This scenario is exacerbated by the lack of comprehensive strategies for the collection, transport, segregation, and management of plastic wastes. Currently, plastic wastes treatment is accomplished by open-air burning, dumping, and landfilling. More advanced technologies, such as thermal (incineration, gasification), chemical (catalytic cracking and selective dissolution), and biological (microbial degradation) methods, are also utilized for treatment and valorisation. However, these high-cost, obsolete, and inefficient technologies result in GHG emissions, toxic fumes, toxins and leachates. Hence, novel technologies for the reuse, recycling, reduction, and valorisation of plastic wastes must emphasize energy, materials, and resource recovery. The article proposes the upcycling of plastic wastes into carbon nanomaterials (carbon microspheres, carbon nanofibers (CNFs), graphene flakes, carbon nanotubes), polymeric composite materials (wood-polyethylene composites, wood-fiber-reinforced plastics), biocrude/bio-oil, fuels, chemicals, and char through solvent/solvothermal treatment and plasma conversion. Solvent/solvothermal treatment can effectively treat and upcycle plastic wastes along with the removal of toxic, recalcitrant and bio-accumulative pollutants such as brominated flame retardants and organophosphorus flame retardants. However, the study identified numerous challenges that currently hamper plastic wastes disposal, management, and valorisation. Hence, sustainable and socially friendly approaches for plastic waste management and valorisation are required to address their short-and long-term impacts on human health, safety and the environment in Nigeria.
