Greenhouses consume large amounts of energy compared with other agricultural activities contributing to environmental pollution. However the current advances in sustainable energy technologies allow the use of benign energy sources for heat and power generation in them. Various renewable and high efficiency energy technologies are currently used in Greece or could be used in the near future in them. The technologies are mature, reliable and cost-effective. Among them the direct geothermal energy, solid biomass, solar-PV, waste heat re-use and co-generation of heat and power. Their use in small or larger greenhouses reduces the environmental pollution due to fossil fuels use, lowers the dependence on imported fuels, promote investments and create jobs in the local societies. Currently modern hydroponic greenhouses in northern Greece use co-generation of heat and power systems fuelled with natural gas. Heat is used in the greenhouses and the generated power is fed into the grid. Others utilize direct geothermal fluids for space heating. Solid biomass is also used for heating them. All of them can cover all the heating needs in greenhouses. Industrial rejected heat from lignite fired power plants in northern Greece could be easily used in the future for heating them. At the same time the high solar irradiance allows the use of solar photovoltaic (PV) systems for power generation in them. Further integration of sustainable energies in greenhouses in Greece requires the governmental support both in the form of financial subsidies and in removing the existing barriers preventing their use.

Pulmonary Changes

Electron microscopy and energy dispersive x-ray microanalysis (EDXA) are found to be very useful tools for identification of etiologic agents in pneumoconiosis or interstitial pulmonary disorders. Pulmonary interstitial fibrosis and granulomatosis are frequently associated with occupational and environmental pollution. Numerous reports of pneumoconiosis in various occupations such as coal and gold miners are presented in the literature. However, there is no known documented case of pulmonary changes in workers in the sandpaper industry. This study reports a rare case of pulmonary granulomatosis containing deposits from abrasives of sandpaper diagnosed by using EDXA.

Vapor Absorption

The problem of losses of oil products from leaks during their storage and transportation at oil supply facilities is considered. The influence of oil product leaks on the environmental situation around oil depots and gas stations is shown. A detailed overview of existing methods and tools for detecting leaks of petroleum products from storage facilities is presented. The evaluation of their effectiveness. Two methods for detecting oil leaks and devices based on them are proposed. The first device monitors the movement of liquid in the tank, the second-detects petroleum products in wastewater. The problem of recovery of petroleum vapors and environmental pollution from the release of vapors of light fractions into the atmosphere is also considered. An overview of existing methods and means of recovery of petroleum vapors is presented. Two methods and devices for capturing oil vapors and returning them to the reservoir are proposed, based on different principles: vapor absorption in the cooled oil product and vapor recovery on the principle of the Carnot cycle. It is shown that these devices can provide effective detection of oil leaks and recovery of their vapors, as well as improve the effectiveness of environmental protection at modern gas stations and tank farms.
