Aiming at the complexion in which the information lost in index ration, the matter element method was put forward to evaluate the ecosystem health in mining area. Making use of the model set up, the weight was built up by the method of index number heavy, the matter element, clas- sical field, and limit field were set up. The rating hierarchy was calculated by relating function. As a case study in the mining area of Pingyangsi Town, the results show that the ecosystem is good and sustainable from 2003 to 2006, but the healthy degree is not high, and some indexes have depravation.展开更多

Recently, bioplastics are one of the most innovative environmental friendly materials developed. Therefore, this paper will look at aspects of the bioplastics from the perspective of sustainability, advantages/disadvantages and standards. The global bioplastics market is thought to be growing at a rate of 20%-25% per year. They have some advantages such as lower carbon footprint, independence, energy efficiency, and eco-safety. However, they have some disadvantages such as high cost, recycling, reducing raw materials, misused of terms and lack of legislation. For the sustainability, recycling systems and production technology may be developed for bioplastics and by-product should be used for their production. Also, there is much standardization about them. It is important to have comparable international standard methods. Therefore, there is an urgent need to standardize all details. A new guide and standard for just bioplastics should be developed for production, usage and bioplastic waste management for every country in the world.展开更多

Most consumers do not understand either the PCF statement or the PCF calculation. The public message of a PCF label does not conform to the terms of sustainability. At first sight, PCF seems to be an opportunity to communicate the sustainability aspects of food to consumers, but too many different approaches to defining PCF exist in Europe. Additionally, the use of a ＂green＂ PCF label may distort trading conditions because of the lack of PCF-issuing authorities in accordance with World Trade Organization （WTO） standards. Hence, PCF may ultimately deceive consumers through its misapplication if the PCF calculation is not aligned to internationally accepted standards.展开更多

However, this development relates to natural resources depletion and deterioration of quality of life in rural population, especially in smallholder farmers. Thailand has practiced the New Theory Agriculture （NTA）, one application aligned with sufficient economy. This theory not only remedies damaged natural resources but also helps smallholder farmers to improve quality of life; and it is analogous to local food supply chain theory, that is well-known in western countries. However, NTA has not been measured its sustainability. Following sustainable food criteria and sustainable agriculture criteria, this paper uses an Indicator of Sustainable Agricultural Practice （ISAP） to measure sustainability at farm level of small rural community＇s network called Inpaeng, a case study that has practiced NTA. The result of assessment in this case implies that NTA yields sustainability to local food supply chain more than monocrop system.展开更多

The current major limitation lies in the poor detection limits of the targeted pollutant＇s trace concentrations by the available conventional techniques. In order to elaborate a novel ＂living＂ self assembled electrochemical 3-D biosensor, the authors propose a new concept to overcome this shortcoming. The advantages of the properties of polyelectrolyte-functionalized NBs （nanobeads） are combined along with the use of non covalently strongly bound micro-organisms. The designed 3-D biosensor is all the more promising as it has showed a significantly improved sensitivity. In fact, the detection limits of the tested heavy metals （cadmium and mercury） were as low as 1.0 × 10^-12 mol.L-1 and six to seven orders of magnitude lower than those provided by conventional 2-D biosensors. Furthermore, it is potentially applicable to a wide range of bioreceptor-pollutant detection systems.展开更多

First, as the new normal is a natural phase of long-term development in the country's renaissance, recognition of it helps policy-making to hold a historical perspective and maintain a patience in the face of growth slowdown. Second, the new normal as the logic of China's economic development underlines the necessity and urgency of transforming growth patterns and growth drivers. Third, different from the "new mediocre" of the world economy, the new normal reveals great potentials of sustainable growth of the Chinese economy that must be tapped through structural reforms.展开更多

BIM should be used for this. Building Information Modellingis a collaborative process where all stakeholders integrate and optimize their information in a digital 3D model. Sometimes it is called Green BIM. But what exactly is that？ Is the International Standard Organization IFC standard useful for this？ And is it compatible with new developments in parametric design？ Advantages and disadvantages of BIM are listed. Full parametric design is needed because it keeps the design flexible and open for changes until the end of the design process. However it is not compatible with IFC; only object parametric design is. A possible way out of this paradox could be the use of scripts that only create objects if they are not already in the BIM database and otherwise only adapt their properties. An example of parametric sustainable architectural design explains the mentioned issues.展开更多
