- To explore the state of waste oil management systems on the

territory of Finland, Leningrad region and Saint-Petersburg,

Russia;

- To propose a few scenarios to be analyzed based on the

common practices in the world;

- To analyze and compare the environmental performance of the

proposed scenarios.

Objectives of the study

3 02.03.2016

Waste oil

- is a mineral or synthetic lubricant oil that becomes waste after losing

its properties and getting contaminated;

- is classified as a hazardous waste.

Waste oil management system

- includes processes such as generation, collection, recycling, and

disposal, reporting, monitoring and etc.

- and results in various environmental, economic and social impacts.

Improper waste oil handling leads to aquatic life damage and

contamination of the soil.

Research problem

4 02.03.2016

Regulation on waste oils:

− Federal Law No. 89-FZ on industrial and consumer waste

− GOST 21046-86 on waste oil products

− March 2014 – a new legislation on waste oil management has been introduced ТР ТС

030/2012.

• Importing companies and manufacturers of lubricant oil should organize a system

for waste oil collecting and introduce new plants for waste oil utilization.

Waste oil management

− If the waste oil is of good quality, it will be collected and producer will be paid;

− If the waste oil is of poor quality, producer has to pay disposal fee.

− Mainly incineration of waste oil.

Waste oil collection and transportation

Reclamation – recycling of segregated used industrial oils, especially hydraulic oils. These oils are simply centrifuged and/or filtered. Low quality lubricants oil can be applied (chain saw oil).

Re-refinery – process involves different technologies in order to turn waste oil back into a virgin base oil substitute (base oil N150 API Group II + by products)

Incineration - waste oil combustion with electricity and/ or just heat production.

Small boilers – incineration of waste oil with heat production.

Cement plant – waste oil used as a fuel.

Eutrophication Potential [kg Phosphate-Equiv.]

Significant reduction in all studied impact categories can be achieved by:

proper waste oil collection,

waste oil treatment in the official treatment plants.

Regional cooperation in waste oil management can improve the environmental performance of the studied systems.

By directing the waste oil incinerated in big industrial installations to existing re-refining plant it is possible to reduce:

GWP by 2420 t CO2/a,

AP by 15 t SO2/a,

EP by 0,6 t Phosphate/a,

HTP by 315 t DCB/a.

Regional cooperation is technically possible,

However,

it may include contradictory business interests

and it is complicated from the permission point of view.

There is need for political and economic initiatives to enable the sustainably effective use of the existing capacity for waste oil recovery.
