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).
ttz Bremerhaven is a provider of research services and operates in the field of application-oriented research and development. Under the umbrella of ttz Bremerhaven, an international team of experts are working in the areas of food, environment and health.Contact:

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
