Conference on the Human Environment held in Stockholm, Sweden. The RSP aims to address the accelerating degradation of the world's oceans and coastal areas through the sustainable management and use of the marine and coastal environments, by engaging neighbouring countries in comprehensive and specific actions to protect their shared marine. Olive oil industry is one of the most important industries in the world. Currently, the land devoted to olive-tree cultivation around the world is ca. 11 × ha, which produces more than 20 × t olives per year. Most of these olives are destined to the production of olive oils. The main by-products of the olive oil industry are olive-pruning debris, olive stones and different pomaces.
IWA Publishing is a leading international publisher on all aspects of water, wastewater and environment, spanning 15 industry-leading journals and a range of books, digitally available on IWAPOnline. Blue-Green Systems now open for submissions. Solid Waste and Marine Litter Contents. Effects; Environmental; Economy/Aesthetics; -Based Sources and Activities (LBS Protocol) of the Cartagena Convention is an important framework for combating solid waste at sea (marine litter). Annex I lists Primary Pollutants of Concern which include “persistent synthetic and other materials.
Chapter 7 Solid waste management Solid waste refers here to all non-liquid wastes. In general this does not include excreta, although sometimes nappies and the faeces of young children may be mixed with solid waste. Solid waste can create significant health problems and a very unpleasant living environment if not disposed of safely and.

THE DEGRADATION OF KRAFT MILL WASTE IN A MARINE ENVIRONMENT INTRODUCTION The Kraft Process Liquid industrial wastes are having an Increasing effect upon our environment.
One of the major producers of liquid wastes is the wood pulp industry. In recent years pulp production facilities have been expanded to meet the.

If we also assume constant density, then integration and rearrangement yield simple algebraic solutions for the mass as a function of time and the time for complete degradation t d (eqs 4 and 5) (4) (5) Using a value of k d = μm year –1 (median estimated degradation rate for HDPE in the marine environment, vide infra) leads to a predicted time for complete degradation of the HDPE film t d of Author: Ali Chamas, Hyunjin Moon, Jiajia Zheng, Yang Qiu, Tarnuma Tabassum, Jun Hee Jang, Mahdi M.
Abu-Omar. On the other hand, as reported by Elisa et al. (), the removal of color from kraft mill wastewater was significant only at an appropriate range of carbon source concentration.
Excessive carbon source resulted in a decline in enzyme activity of lignin peroxidase, Mn peroxidase, laccase and β-glucosidase, and therefore reduced the removal efficiency of COD from by: The scale of waste discharges to the marine environment from the pulp and paper industry in various parts of the world is outlined and a brief description of the major characteristics of such wastes is given.
The information available on the direct toxicity of these wastes to marine fauna and flora is assessed including both lethal and sublethal by: CHLORINATED WATERS DISCHARGED TO THE MARINE ENVIRONMENT etc.
In spite of all these problems, it is quite remarkable that in going to more subtle effects, a convergence of data is observed and that, an average chlorine concentrations as low as mg may harm the coastal marine by: In this book, types of Wastes, environmental and health impacts of wastes during handling, Waste management techniques according to 3R principle (reduce/ reuse, recovery& recycle), Mechanical.
The introduction of net-pens leads to a break in the natural assimilation of waste in the marine environment. The pens convert coastal ecosystems, such as bays, inlets, and fjords, into aquaculture ponds, destroying nursery areas that support ocean fisheries.

Briquettes Production from Olive Mill Waste under Optimal Temperature and Pressure Conditions: Physico-Chemical and Mechanical Characterizations by Saaida Khlifi 1, Marzouk Lajili 1, Saoussen Belghith 2, Salah Mezlini 2, Fouzi Tabet 3 and Mejdi Jeguirim 4,5,*Author: Saaida Khlifi, Marzouk Lajili, Saoussen Belghith, Salah Mezlini, Fouzi Tabet, Mejdi Jeguirim.
The electrochemical degradation of agri-based paper mill wastewater (black liquor) was investigated in a 2 dm3 electrolytic batch reactor using iron plate electrodes. Of the four- six- and eight-plate configurations, a current density of A/m2 at neutral pH with a six-plate arrangement was found to be optimal, achieving a maximum chemical oxygen demand (COD) and color removal of 80% Cited by: The comprehensive study even went so far as to identify that addressing the issue of increases in nutrients from land-based sources, including the pulp and paper mill, was the “most important marine environmental quality issue in the near shore areas” and the “highest priority for investigation.”.
The environmental impact of paper is significant, which has led to changes in industry and behaviour at both business and personal levels.
With the use of modern technology such as the printing press and the highly mechanized harvesting of wood, disposable paper became a relatively cheap commodity, which led to a high level of consumption and rise in global environmental issues such. In recent years, there have been emerging concerns regarding the fate and effects of pulp and paper mill effluents on the environment.
Countries throughout the world are focusing attention on the implementation of regulatory and monitoring programs. In response, industry has begun to implement a variety of process and treatment technologies designed to minimize or eliminate the potential.
The degradation of solved organic substances, mainly partially degraded starch, is done by a layer of microbial organisms that grow on the hollow filling of the biofilters. The “healthy biological growth” of the bacteria’s in the biofilters can be optimised by a well balanced nutrient dosing rate.
The project — a new effluent treatment facility on the site of the Abercrombie, N.S. kraft mill and a kilometre pipeline emptying into the Northumberland Strait — is currently under review. The pipeline in question is for Northern Pulp's year-old bleached kraft pulp mill in Pictou County on the north shore of Nova Scotia.
If approved, it would be almost a metre in diameter and 10 kilometres long, carrying millions of litres of effluent and releasing it through six dispersal pipes into the Northumberland Strait. In environment, lignin is probably hydrolyzed by the group of microorganisms shown in Table 1.
The studies on bacterial enzymology for the degradation of lignocellulosic waste are fewer than those of fungi due to wood degrading bacteria that can tolerate a Author: Adarsh Kumar, Ram Chandra.
