On May 8, 2015, the U.S. Environmental Protection Agency (EPA) issued a direct final rule for 25 chemical substances that were the subject of premanufacture notices (PMN), including several biobased chemical substances. The rulemaking under Section 5, known as a significant new use rule or SNUR, requires persons who intend to manufacture (including import) or process any of these 25 chemical substances for an activity that is designated in the SNUR as a significant new use to notify EPA at least 90 days before commencing that activity. The required notification provides EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs. The rule will be effective July 7, 2015.
On-time Pest Protection
Farming can be a beautiful job under an open sky. But sometimes that ”open sky” determines the flow of farming, total yield, and productivity according to the weather (rain, drought, hail, frost). Since the weather is a major factor in farming, farmers need to manage certain practices to protect their crops from bad weather conditions as well as from various insects and diseases caused by the weather. As they struggle to remain profitable in a highly competitive global economy, farmers must find...
Non-chemical Pre-plant Soil Disinfestation
The battle with pests, diseases and weeds is an everyday problem for every farmer. Due to the fact that 40% of the world’s food production is lost due to pests and diseases, farmers need to manage crop protection. An excellent example of the need for pesticides is cotton. It is a crop that is affected by various pests. Cotton farming accounts for more than 25% of all insecticides and 12% of all pesticides used worldwide. Although pesticides play a major role in crop protection, there is a global problem...
Chill Out: Chemical Descaling of Condensers Maximizes Efficiency
Chiller units — open loop or closed loop — naturally experience performance degradations over time. As noted by Facilities Net, chillers and companion condenser units are often the single biggest energy spend in an organization and despite predictive maintenance methods such as vibration analysis, infrared thermography and rotor bar testing, scale and foiling still occurs. Here’s a look at the impact of scale on your condenser system and the steps you can take to maximize efficiency. Sources...
What is it about this soil that protects plants from devastating disease?
Figuring out why certain soils keep plant parasites at bay could be a boon for agriculture around the globe Plants around the world are constantly under attack — often with big implications for humans. In the 1960s, millions of elm trees in Britain, France and the U.S. fell victim to Dutch elm disease, which clogs the vessels that carry life-giving water to the trees’ leaves. Starting in the late 1980s, Brazil’s thriving chocolate industry crumbled when witches’ broom disease devastated...
Phosphorus control protects surface waters
Phosphorus is the decisive factor for excessive algae and plant growth in water bodies, that’s why quality standards require reductions in the amount of phosphorus released from wastewater treatment plants into rivers and lakes. In recent years, the outlet limit values have not only been reduced on national levels. Depending on the vulnerability of ecosystems, especially low target values have been defined on regional levels. Examples are regional values for Lake Constance, the Baltic Sea or the Colorado...
