HCME: An Environment-Friendly I.C. Engine Fuel

The study revealed that Hura crepitans oil is a good candidate for Hura crepitans methyl ester (HCME) production. Two steps (esterification and transesterification) production stages influenced the high yield of HCME. Three possible experimental runs were performed in each step, the best of the three conditions were 1.45 (% v/v) for H2SO4 conc., 5:1 for methanol/oil molar ratio, 40 min for reaction time which gave 1.06 % for FFA in the first step, in the second step, 92.70 %(w/w) of HCME was obtained at 0.55% KOH, 5:1 methanol/oil molar ratio, 60 oC temperature and 30 min reaction time. The produced HCME had fuel properties which satisfied both ASTME D6751 and EN 1424 standards. The fatty acid profile of the HCME revealed the dominant fatty acids were linoleic (64.50%), oleic (17.54%) and palmitic (12.70%). Exhaust emissions from an internal combustion (I.C.) engine revealed that there is 60% decreased in CO, 58% decreased in NOx, 60% decreased in HC, 39% decrease in smoke opacity and 42% decreased in BSFC at B20, respectively. Flue gas temperature increased by 12% at B20, 45% increased in BTE at B50 when compared to pure diesel (AGO). Hence, it can be concluded that B20 (20% HCME + 80% AGO) will provides the best emission reduction at the lowest cost

GEOPOL®. The innovated environment friendly inorganic binder system

This paper deals with the complete technology of inorganic geopolymer binder system GEOPOL® which is a result of long term research and development. The objective of this paper is to provide a theoretical and practical overview of the GEOPOL® binder system and introduce possible ways of moulds and cores production in foundries. GEOPOL® is a unique inorganic binder system, which is needed and welcomed in terms of the environment, the work environment, and the sustainable resources. The GEOPOL® technology is currently used in the foundries for three basic production processes/technologies: (1) for self-hardening moulding mixtures, (2) sand mixtures hardened by gaseous carbon dioxide and (3) the hot box technology with hot air hardening. The GEOPOL® technology not only solves the binder system and the ways of hardening, but also deals with the entire foundry production process. Low emissions produced during mixing of sand, moulding, handling, and pouring bring a relatively significant improvement of work conditions in foundries (no VOCs). A high percentage of the reclaim sand can be used again for the preparation of the moulding mixture.Web of Science19111610

Environment Friendly Industrial Growth for Sustainability

Any country's environmental problems are related to the level of its economic development, the availability of natural resources and the lifestyle of its population. In India, the rapid growth of population, poverty, urbanization, industrialization and several related factors are responsible for the rapid degradation of the environment. Environmental problems have become serious in many parts of the country, and hence cannot be ignored.  80% of the total population of Odisha, a state of Eastern India depends on agriculture. But most of them are small and marginal farmers. 48% farmers households are indebted. The state, in reality, is the second poorest state in India today, next only to Bihar. Industrialization is the only alternative to develop the economic status of the state but the darker side of it is environmental pollution. Hence if the growth of industry can be accelerated along with environmental protection then a balance can be maintained. So this paper examines the growth of cottage industries in the state of Odisha through different statistical analysis as this is an eco-friendly industry and simultaneously a prospective area for the growth of indigenous talent

Environment friendly industrial nanotechnologies

INVESTIGATING PREFERENCES FOR ENVIRONMENT FRIENDLY PRODUCTION

This paper reports some preliminary results on a mixed logit random utility analysis of conjoint data from costumers' preferences over agricultural products. The data are collected via a telematic sample representative of Italian households. The survey instrument was implemented via a computer supported system. A multivariate normal full correlation structure is imposed in the mixed logit estimation and the implications of such a taste structure are examined.

Means of environment-friendly protection of white cabbage against the onion thrips

fejes káposzta-fajta ellenállóságának felmérésére került sor szabadföldi körülmények között, a dohánytripsz spontán betelepedése mellett kialakuló kártétel mértéke alapján. Minden fajta károsodott kisebb-nagyobb mértékben. Az Autumn Queen F1, Balashi F1, Riana F1, Ammon F1 és Quattro F1 fajták károsodtak a legkevésbé, így rezisztens minősítést kaptak. Az időzített termesztés kártételt mérséklő hatását több augusztusban és az ősz folyamán is értékelt fajta a későbbi időszakban megfigyelt kisebb károsodása szemlélteti. A rendkívül ellenálló Autumn Queen F1 fajta esetében az időzítésnek nem volt kimutatható hatása a kialakult csekély kártételre

Environment-friendly schemes in intensive shrimp farming.

International environmental pressure groups call for shrimp importing countries to impose a trade embargo against farmed shrimps produced in a manner considered deleterious to the environment. In fact, Europe had banned in 2000 the importation of shrimps from some Asian countries. The subject of such protest actions included: (1) discharge of substances potentially harmful to marine organisms (chemicals used during pond preparation and therapeutants used during culture period); (2) discharge of excessive organic load during regular water change and harvests; and (3) chemical residues in shrimps harvested and marketed. In the Philippines, a mandate from the national government was given to SEAFDEC in 1996 to rehabilitate the shrimp industry, which almost reached the brink of virtual collapse due to diseases brought about by some environmentally destructive practices. Mangrove-friendly aquaculture or what is sometimes referred to as the environment-friendly aquaculture was launched by AQD as a five-year program starting in 1998. The focus was later changed to shrimp culture and made part of the ASEAN-SEAFDEC Fisheries Consultative Group (FCG) collaborative project with AQD as Lead Department for technology development and verification, and Thailand as Lead Country for promoting the technology within the Southeast Asian region
