Use of recycled fiber material for the production of paper and paperboard has a significant share in solving problems related to environmental protection and conservation of energy resources. One of the most important processes for the paper recycling with printing press is a deinking. Perspective method for deinking of waste paper by the method of flotation is the enzyme treatment at neutral pH. The aim of this work is to study the deinking of recycled paper with offset printing press through flotation and use of enzymes. [ABSTRACT FROM AUTHOR]

Abstract
The article presents the author's opinion on five selected technical reports which were discussed at the Photovoltaic Technical Conference held in Provence, France in 2011. These papers reportedly tackles low cost photovoltaic solutions to address the grid parity objectives crucial for competitive electricity produced by renewable energy sources. She comments that the solutions presented are key factors in the success of future photovoltaic technologies for consumer production of electricity.
