Environmental improvement productivity of reuse recycle recovery wastes in the petroleum and petrochemical group Map Ta Put Industrial Estate Thailand
Abstract:
The concept of eco-efficiency has become increasingly popular in the
environmental debate of product systems, processes, and/or companies in recent years.
Eco-efficiency is generally described as a ratio between environmental impact and
value of production.
This study presents an eco-efficiency indicator, called environmental
improvement productivity (EIP), for assessing the environmental improvement from
3R waste of the petroleum and petrochemical (PP) group in the Map Ta Phut Industrial
Estate (MTPIE), Thailand. The EIP is defined as the ratio of total waste as a value of
production to the total amount of CO2 reduction by the 3R activities. CO2 reduction is
an environmental impact value or environmental improvement of 3R waste, which was
evaluated by the CO2 emission calculated from the basis of 3R waste incineration. All
waste and 3R waste generated from the PP group in fiscal year 2007, which was
separated into 4 quarters, was collected and used to create the waste flow diagram of
the PP group. Moreover, characterizations of the industrial waste in the industrial gas
group, utility group, iron and steel industry group and chemical industry group were
studied by creating waste flow diagrams.
The results show that more than 60% of the total waste generated from the PP
group in the MTPIE was classified as 3R waste. The analyzed results of EIP reflect the
trends industrial waste generated from PP group. The EIP trend of reuse and 3R
wastes decreased from quarter 1 to quarter 4 while an increase in the EIP trend of
recycle and recovery wastes was observed. The research demonstrates the
environmental benefits from the 3R waste, which will feed into strategic development
and should encourage 3R activities for to industrial sector in Thailand.
