CASE STUDY #75
1. Headline: Installation of a beer centrifuge
2. Background: The water consumption and COD emission per ton
beer are higher than in corresponding figures from other
breweries, the same is true for the amount of beer loss.
The main cause of beer and raw material loss occurs in the
diatomite filtration process.
To solve this problem, the company, took part as one
demonstration enterprise in the China Technical Assistance
Project of the World Bank. During 1993, representatives
from ZBBC, six other companies and institutions such as
the National Environmental Protection Authority (NEPA),
the Chinese Research Academy for Environmental Sciences
(CRAES) and the Beijing Environmental Protection Bureau
(BEPB) were trained in cleaner production by consultants
from UNEP/IE and IVAM Environmental Research (Amsterdam
University). Part of the training included carrying out
cleaner production assessments in the participating
companies.
Zhongce Beijing Beer Company (ZBBC) is located in the east
of Beijing city. There are 1,550 employees, 310 of which
are technical staff. The primary products are 11 degree
and 12 degree bottled, barrelled and canned, Beijing Beer.
The production capacity is 120,000 tons of beer per year.
3. Cleaner Production Principle:
4. Description of Cleaner Production Application:
The company set up a cleaner production audit team headed
by the company manager and the chief engineer. The audit
team evaluated the production and wastes generated in the
company and came up with 27 cleaner production options.
Fifteen of them have been implemented.
The benefits achieved follow:
a. The output of barrelled and canned beer increased by
3,200 tons compared to the same period in the previous
year with economic benefits of 3.66 million RMB Y and the
COD emission reduction by 35.
Two tons were saved by implementing process modifications.
b. Raw materials saving and waste reduction resulted in
economic benefits of 1.033 million RMB Y and COD emission
reduction by 220.5 tons
5. Economics:
Investment: 430,000 US$ and 225,000 RMB Y
Annual extra cash flow: 1.046 million RMB Y
Payback period: 2.6 years
The internal rate of return: 36.82%
6. Advantages: The benefits of installing a beer centrifuge
are as follows:
reduced beer loss
diminished COD concentration in the effluent
saving raw materials

10. Reviewer's Comments: This case study was taken from the
document: "Cleaner Production in China," published by the
National Environmental Protection Agency of China. It was
edited for the ICPIC diskette in August 1995, but has not
undergone a formal technical review.
