Carbon storage potential in natural fiber composites

The environmental performance of hemp based natural fiber mat thermoplastic (NMT) has been evaluated in this study by quantifying carbon storage potential and CO₂ emissions and comparing the results with commercially available glass fiber composites. Non-woven mats of hemp fiber and polypropylene matrix were used to make NMT samples by film-stacking method without using any binder aid. The results showed that hemp based NMT have compatible or even better strength properties as compared to conventional flax based thermoplastics. A value of 63 MPa for flexural strength is achieved at 64% fiber content by weight. Similarly, impact energy values (84–154 J/m) are also promising. The carbon sequestration and storage by hemp crop through photosynthesis is estimated by quantifying dry biomass of fibers based on one metric ton of NMT. A value of 325 kg carbon per metric ton of hemp based composite is estimated which can be stored by the product during its useful life. An extra 22% carbon storage can be achieved by increasing the compression ratio by 13% while maintaining same flexural strength. Further, net carbon sequestration by industrial hemp crop is estimated as 0.67 ton/h/year, which is compatible to all USA urban trees and very close to naturally, regenerated forests. A comparative life cycle analysis focused on non-renewable energy consumption of natural and glass fiber composites shows that a net saving of 50 000 MJ (3 ton CO₂ emissions) per ton of thermoplastic can be achieved by replacing 30% glass fiber reinforcement with 65% hemp fiber. It is further estimated that 3.07 million ton CO₂ emissions (4.3% of total USA industrial emissions) and 1.19 million m³ crude oil (1.0% of total Canadian oil consumption) can be saved by substituting 50% fiber glass plastics with natural fiber composites in North American auto applications. However, to compete with glass fiber effectively, further research is needed to improve natural fiber processing, interfacial bonding and control moisture sensitivity in longer run.

Mix proportions and properties of CLSC made from thin film transition liquid crystal display optical waste glass

In this study, controlled low-strength concrete (CLSC) is mixed using different water-to-binder (W/B) ratios (1.1, 1.3 and 1.5) and various percentages of sand substituted by waste LCD glass sand (0%, 10%, 20% and 30%). The properties of the fresh concrete, including compressive strength, electrical resistivity, ultrasonic pulse velocity, permeability ratio and shrinking of the CLSC, are examined. Results show that increases in amount of waste glass added result in better slump and slump flow, longer initial setting time and smaller unit weight. Compressive strength decreases with increasing W/B ratio and greater amounts of waste glass added. Both electrical resistivity and ultrasonic pulse velocity increase with increases in amount of waste glass and decreases in W/B ratio. On the contrary, the permeability ratio increases with increases in W/B ratio, but decreases with greater amounts of waste glass added. CLSC specimens cured for different durations show little changes in length with shrinkage below 0.025%. Our findings reveal that CLSC mixed using waste LCD glass in place of sand can meet design requirements. Recycling of waste LCD glass not only offers an economical substitute for aggregates, but also an ecological alternative for waste management.     

Low priorities for black american leaders: Environmental and occupational health

Summary Black Americans face increased health risks from environmental and occupational exposures when compared with white Americans, but they also face increased risks for more immediate health problems such as HIV infection/AIDS, alcohol and drug abuse, violence, and infant mortality. A survey of more than 1,000 black public health and black political leaders solicited opinions on the relative importance of 1) environmental health and 2) occupational health and safety compared with other public health problems faced by the black community. The survey also determined opinions about the degree to which specific health problems are amenable to change for black Americans and who (or what agency) should spearhead efforts aimed at specific public health objectives.Responding black leaders felt environmental health and occupational health and safety goals were somewhat important for black Americans, but among the most difficult of all public health objectives to meet. Those who felt that the above objectives were very important identified the federal govemment as the primarily responsible party for seeing that the objectives are met.Dr Dona Schneider is Assistant Professor of Public Health at Rutgers University. She teaches epidemiology and biostatistics for the New Jersey Graduate Program in Public Health at the University of Medicine and Dentistry of New Jersey, and holds memberships in both the Environmental and Occupational Health Sciences Institute and the National Institute for Environmental and Health Sciences. Her research spans the health problems of children and minorities. She regularly reviews books for theEnvironmentalist.
