Wine country 酒鄉
Get PDFHigh quality produce from England\u27s green and pleasant land has contributed to the growing reputation of British food, but the country has also been making a name for itself in wine - particularly sparkling - and is stealing the crown from many better-known sites.
英格蘭鄉郊田野出產的優質農作物不僅讓英國食物名聲漸響，連該國釀製的葡萄酒，特別是氣泡酒，也在品質上勝過許多知名度更高的產酒區
An integrated approachfor the benchmarking of production facilities’ environmentalperformance: data envelopment analysis and life cycleassessment
No full textEnvironmental impacts have become an important consideration in the manufacturing industry due to increasing public pressure for environment protection and the requirements of recently launched legislations. Data envelopment analysis (DEA) is a widely adopted methodological approach for the benchmarking of the relative efficiency of different production units. Changes in production efficiency may affect environmental impacts. DEA can be used for identifying the most efficient production facility and hence, the environmental impacts generated from the different production lines can then be benchmarked. Life cycle assessment (LCA) is carried out to quantify the full environmental impacts of a product from ‘cradle to grave’. The integration of LCA with DEA, efficiency and environmental impact of different production processes for a certain family of products can be evaluated and benchmarked. The proposed two-stage approach can help to reduce the aggregate environmental impacts of the manufacturing phase and is used to benchmark the environmental performance of several production lines in a manufacturing company
Tree density and diversity in Hong Kong’s public housing estates: Fromprovision injustice to socio-ecological inclusiveness.
No full textSocio-economically underprivileged urban communities might suffer from restricted access to urban forests. Environmental injustice research on urban greenery in Asian cities is lacking. Public housing estates in Hong Kong, accommodating low-income households and over half of the 7.45 million population, were investigated for injustice in tree provision. Two clustering schemes used socio-economic and ecological characteristics to classify 93 estates. Factor analysis of 14 socio-economic variables identified four factors related to deprivation, namely ageing population, overcrowding, working poor with high academic qualifications, and marginalised language minorities. Principal component analysis of six ecological indices returned two components related to tree density and diversity. Estates with ageing population and more language minorities had the least urban tree provision indicated by low tree density. However, estates beset by overcrowding and working poor with high academic qualifications had the highest tree diversity indicated by the highest species evenness. Estates with the lowest language minorities had the densest but the least diverse tree stands. An alternative clustering scheme delineating ecological clusters substantiated the observed urban-tree patterns with respect to socio-economic characteristics. Estates with higher tree density and diversity had higher population density indicating overcrowding. Estates with lower tree density and diversity had more ageing population language minorities. The results highlighted the need to modify tree provision in response to changing estate demographics. From the research findings, five strategies were developed to adjust the amount and composition of the estate tree stocks to achieve greater social inclusion
Nb(Ta)-based solid acid modified Pt/CNTs catalysts for hydrodeoxygenation of lignin-derived compounds
Get PDFEfficient upgrading of lignin bio-oils into oxygen-free liquid alkane fuels is a challenging task owing to the incompatibility of the phenolic feedstock with conventional fuels and the availability of effective hydrotreating catalysts based on the current refinery infrastructure. In this work, a series of solid acid nanosheets (HNbWO6, HNbMoO6, HTaWO6) modified Pt/CNTs bifunctional catalysts were evaluated in hydrodeoxygenation (HDO) of lignin-derived compounds. The effects of types of nanosheets and the synergistic effect between metal sites and acid sites were discussed via HDO of diphenyl ether. Pt/HNbWO6/CNTs catalyst exhibited the most efficient performance for the HDO of diphenyl ether to cyclohexane (conversion: 99.7%, selectivity: 96.4%) at 200 °C, 3.0 MPa. Several lignin aromatic model compounds including phenol, anisole, 2-phenylethyl phenyl ether and guaiacol were also investigated over Pt/HNbWO6/CNTs catalyst. Due to the different bond-dissociation energies of CeO bond and steric hindrance effect, guaiacol and phenol are more difficult to be converted than diphenyl ether and anisole based on the yield of cyclohexane. It was found that the Pt/HNbWO6/CNTs catalyst exhibited favorable stability. These results validated that it is desirable to utilize this catalyst in the HDO of actual lignin macromolecules into hydrocarbon fuels

No full textSustainable adaptive reuse – economic impact of cultural heritage
Get PDFPurpose
The purpose of this paper is to investigate the positive externalities of adaptive reuse of heritage buildings and the economic impact on adjacent residential property prices as adaptive reuse is emerging as a significant heritage management and cultural heritage conservation practice recognized by the International Council on Monuments and Sites.
Design/methodology/approach
Through mixed methodologies of hedonic price model and case studies of three tenement houses in Hong Kong, this paper argues that the adaptive reuse of heritage buildings increases the values of residential properties within the district and revitalizes the area economically and culturally because of the positive externalities generated from the cultural heritage.
Findings
The findings have identified key cultural heritage values of adaptive reuse via the case studies as well as the major intangible cultural values associated with the heritage assignment. On the other hand, the hedonic regression also verifies that key variables such as heritage completion and distance from heritage show significance to the property prices of adjacent residential units.
Practical implications
The research is useful for heritage conservationists, policy makers and urban planners in other cities with regards to management and implementation of sustainable cultural heritage revitalization schemes for economic benefits.
Originality/value
The research is original in its scope and context, and is one of the first of its kind for a high-density metropolitan context in Hong Kong and is significant in demonstrating the economic impact of the heritage practice of adaptive reuse
