The bacterial isolates formed the basis of a consortium represented by 1:1 proportion and exhibited ability to reduce biological oxygen demand of the petrochemical wastewater by 88% under immobilized condition in laboratory. Response surface methodology-based optimization revealed a reduction of 93.33% biological oxygen demand within 12 h from simulated wastewater at 37◦C which had a starting concentration of 400 mg L− 1 of toluene.

Nghi Son is an economic zone oriented to developing heavy industry and petrochemicals and has potential to become the most substantial economic zone in the North Central region. The zone is also one of the potential waste sources polluting Thanh Hoa coastal waters. Numeric modeling using Delft3D software package with different scenarios: Current status scenario, controlled discharge scenario, and incident scenario was developed to simulate states of some pollutants of organics and nutrients from the zone to Thanh Hoa coastal waters in different periods.

The NMR spectra of 15 novel quinolines containing 11 - 34 carbon atoms and bearing substituents such as hydroxyl, sunfo, chloro, bromo, amino, azo and carboxymetoxy groups were recorded in DMSO at 298 - 300 K. For seven quinolines, the 13C-NMR signals were assigned on the basis of an analyzation of the cross peaks in the HSQC and HMBC spectra.

This article proposes an evaluation approach and carried out modeling of the impact of the introduction of energy saving technologies in the petrochemical enterprises using the DuPont model. The article is relevant due to the fact that the organization of energy and resource saving technologies in the petrochemical complex is still not been fully resolved and require further research of their effectiveness and efficiency evaluation at the sectoral and micro- levels of management.

Petrochemical Industry manufacturing petrochemical product-generate waste containing organic compounds. As the toxicity level of most of these compounds is high, there is an increasing demand for remediation of such sites that involves removal of the offending compounds. Bioremediation uses living systems or biological products to biodegrade waste, with the objective being reduction of waste to chemical forms that can be assimilated into natural cycles. In the present study, the use of micro-organism for bioremediation has been carried out.

Phenol and its components are extremely toxic and can easily be isolated from different industrial sewage such as oil refinery, petrochemical industry and mines, especially chemical factories causing pollution in water bodies. Rivers and oceans are contaminated on a large scale with these toxic compounds. In the past, physicochemical method was used for the elimination of phenol and its compounds, but today, bioremediation is preferable.

In the past years, various studies have been done on biodegradable materials to replace petroleum based plastics for food packaging application. For this purpose, biopolymers are considered the most favorable material because of their biodegradable nature and long shelf life properties like resistance to chemical or enzymatic reactions. Keeping in view the non-renewable nature and waste disposal problem of petroleum based plastics; newer concept of use of bioplastics came into existence. Bioplastics are derived from renewable resources i.e.
