Bankruptcy in the Pulp and Paper Industry: Market’s Reaction & Prediction
This paper examines North American pulp and paper company bankruptcies that occurred between 1990 and 2009. We demonstrate that shareholders suffer substantial losses (37%) during the month a bankruptcy occurs. Encouragingly, we show that financial ratios are useful in predicting firm failure and that failed firms are less profitable, more liquidity constrained and higher in debt leverage. Usin...
متن کاملStable isotopes trace estuarine transformations of carbon and nitrogen from primary- and secondary-treated paper and pulp mill effluent.
Stable isotope analysis of a novel combination of carbon and nitrogen pools traced inputs and processing of primary-treated (PE) and secondary-treated effluent (SE) from a paper and pulp mill (PPM) in a temperate Australian estuary. Distinct carbon stable isotope ratios of dissolved organic carbon (DOC) near the PPM outfall indicated large PE and reduced SE inputs of DOC. DOC was remineralized ...
متن کاملApplication of Trapa bipinosa for the treatment of pulp and paper industry effluent.
The ability of aquatic plants to absorb, translocate and concentrate metals has led to the development of various plant-based treatment systems. The potential to accumulate metals like iron, nickel, manganese and copper by Trapa bipinosa was assessed by subjecting them to different effluent concentrations of pulp and paper industry under laboratory conditions. Trapa showed the ability to accumu...
متن کاملutilization of electrochemical method (ec) for pulp and paper mill industry's effluent treatment
growing the water consuming and shortage of available fresh water resources, make “effluent reuse” an unavoidable issue in industry for supplying a part of needs for required water. on the other hand, increment in the production of paper products from wood and recycling their consumed products which release pollutants to the environment has increased the environmental concerns. thus, in present...
متن کاملBiological Approach for the Treatment of Pulp and Paper Industry Effluent in Sequence Batch Reactor
Pulp and paper industrial effluent is rich in recalcitrant compounds and causes pollution. For the treatment of such compounds activated sludge process is frequently used in which F/M ratio is kept low. This treatment results in effective biochemical oxygen demand removal but other waste water parameters are not reduced effectively due to lack of dissolve oxygen. In the present study sequential...
