Using technology to link wastewater and energy wood to create bioenergy regions in China
The development of a cost-efficient, water-saving and sustainable irrigation system for plant wastewater facilities is one of the objectives of BIOWARE, a project promoted by the Federal Ministry of Economic and Technology. Above all in rural areas of China, wastewater treatment systems are either inadequate or non-existent.
A nutrient solution produced by means of biological wastewater recycling and comprising wastewater and groundwater could be the answer to this problem and at the same time it facilitates the efficient irrigation of energy wood plantations. Through the new irrigation method, not only water and money will be saved, but also the use of conventional fertilizers will be reduced by the controlled application of nutrients from the wastewater.
This also contributes to intensifying technology transfer between German and Chinese enterprises. Further co-operative German-Chinese projects in the area of renewable energies might follow, for example in conjunction with the processing of energy wood.
The irrigation system helps to control the water quality and regulate its supply. This takes place online so that the system can be operated without any time delay and from any location via Internet. The prototype developed in BIOWARE for technical implementation comprises three modules: an irrigation module, a control module and a monitoring module. The monitoring module records soil parameters such as moisture. Sensors transmit their measurements to the control module which determines the energy plantation’s nutrient requirements and communicates the exact mixing ratio to the irrigation module. The irrigation module produce a nutrient solution from municipal wastewater and groundwater which irrigates the energy plantation. This irrigation method leads to a greater biomass yield especially in dry regions. At the same time less groundwater is used and there are considerable cost savings in wastewater treatment in small municipal sewage plants.
Currently the Chinese bioenergy market for electricity-, heat- and fuel- materials is undeveloped. The new monitoring and control system contributes a valuable part for regenerative energies. One aim of BIOWARE is to support the Chinese energy policy to increase the share of renewable energies within the total energy generation to 16% until 2020.
BIOWARE, co-ordinated by the research service provider ttz Bremerhaven, started in October 2009 with a total budget of about 592.000 Euro. The plan is to install the prototype of the wastewater recycling system in spring 2011 in Yangjiteng, a small town near Chengdu with about 20.000 inhabitants. After a successful test phase, the system can be marketed and established as an overall bioenergy wastewater concept in other regions of China and thus bioenergy regions can be created (similar to the German bioenergy regions under www.bioenergie-regionen.de).

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
