Assessment Title:
Energy Evaluation of a Dairy Company with
Recommendations of GHG Emissions Reduction
Assessment set by Dr. V. Stojceska

Module Leader:
Dr. V.Stojceska

MAIN OBJECTIVES OF THE ASSESSMENT:
To provide knowledge and awareness of environmental evaluation techniques and analysis for the
dairy company according to the current EU regulations and guidelines with recommendations to
reduce GHG emissions.

BRIEF DESCRIPTION OF ASSESSMENT:
Students are asked to carry out an energy evaluation of a Dairy Company located near Corinth,
Greece. The company is interested in reducing GHG emissions of 100% by 2050 and proposes the
use of renewable energy to create an environmentally sustainable integrated community. The main
processes of the company include pasteurization, separation, homogenization, mixing and
fermentation for production of skimmed milk, yogurt and cream, as presented in Figure 1. The green
lines signify the production process while red lines the heating and blue lines the cooling systems.
The plant operates from 9:00am to 5:00pm during weekdays and requires around 1,600 MWh of
electricity and 119,000 m3 of Liquified Petroleum Gas (LPG) annually. Table 1 presents the nominal
capacity of the components involved in the production process (Figure 1).
You are provided with layout of the company (Figure 1) and data of the nominal capacity of the
components for 2021 (Table 1).
You are asked to carry out analyses of the data provided and propose practical improvements for
renewable energy implementation for energy improvements of the company and reduction of GHG
emissions.
It is recommended to use Energy management or Life cycle assessment software but it is not
compulsory.

LEARNING OUTCOMES FOR THE ASSESSMENT
• Demonstrate an understanding of main
elements of relevant energy
management and current legislation.
• Use energy analysis methods to examine
the energy use of the company.
• Show an ability to analyse data to provide
recommendations for improvement of
the environmental impact
• Present results concisely in an oral
presentation and a written report

ASSESSMENT CRITERIA
The marking criteria for the assignment are the
following:
1. Description of current legislation for
renewable energy use, obligations, incentives
and benefits for businesses – 20%.
2. Description of the examined company in terms
of energy source/consumption – 20%
3. Analysis and discussion of the results of energy
use for the examined company – 20%

4.Recommendations for energy use
improvements, cost saving and GHG emissions
reduction: these should be the result of
calculations to consider energy use and
associated costs and GHG emissions – 40%
