Biorefineries using crops for production of ethanol, biogas
and chemicals - a large-scale demonstration in Nanyang,
Henan province, China of the bio-ethanol industry
under Tianguan recycling economic mode
Du Feng-Guang & Feng Wensheng
9.1 INTRODUCTION
Henan Tianguan Enterprise Group Co., Ltd. (referred to here as “Tianguan Group”) was founded
in 1939. The company is China's oldest and most representative ethanol production company,
one of 520 key national enterprises, one of the five designated fuel ethanol manufacturers, the
only enterprise entered into the national recycling economic test point in the industry, and the
country's main enterprise of new energy and high-tech industry base in Nanyang city.
Tianguan Group has two wholly-owned subsidiaries, eight subsidiaries and four equity sub-
sidiaries. The enterprise has China's largest fuel ethanol production capability with an annual
output of 500,000 tonnes and the largest gluten production line in the world with an annual output
of 70,000 tonnes. At the same time, it has Asia's largest industrial biogas project with an annual
output of 150 million cubic meters, and presently it is China's only enterprise, which owns a
production line with three bio-energy products: fuel ethanol, industrial gas and bio-diesel. The
sales income of Tianguan Group in 2010 is 5 billionYuan.
Tianguan Group has constructed some high-level innovation platforms, including a state-level
enterprise technical center and the joint center of national biomass fuel technologies. Meanwhile
it is planning to build a state key laboratory on vehicle biomass fuel technology with a biomass
fuel research and development platform, which represents China's highest level.
Besides, the national Fuel Ethanol Standardization Technical Committee Secretariat is located
in Tianguan Group. The Commission is the drafting institution of China's fuel ethanol production
and technical standards.
9.2 DOMESTIC AND INTERNATIONAL BACKGROUND AND CONDITIONS
RELATED TO THIS CASE STUDY
Globally, the recycling economy is becoming a trend, and the trend has had a successful practice.
From the aspect of enterprise, the most typical example of the recycling economy is the DuPont
chemical company mode. This mode can be called internal recycling economy in the company,
which is to organize the material cycle between the various processes in the plant. At the regional
level, an eco-industrial zone can be formed through the inter-firm industrial metabolism and
symbiotic relation. Denmark Kalundborg eco-Industrial zone is currently the most successful
eco-industrial zone around the world, and is the most typical example in the industrial eco-
system. In addition, it formed a dual recycling system mode - collection and disposal of packing
waste in Germany, which is the typical mode of recycling economy operation.
In recent years, Chinese enterprises have been processing a large number of meaningful explo-
rations and practices for the development of the recycling economy to strongly push China to
take a new industrialization road and achieve sustainable economic and social development.
