Pulp and paper mills still pollute our water, air, and soil. This guide explains how mills pollute, gives a vision for a sustainable pulp industry, and shows how British Columbia's "Zero AOX" law can help achieve a pulp and paper industry that sustains the environment, healthy communities, and jobs. This Pulp Pollution Primer explains the basic facts of pulp mill pollution, presents alternatives, and examines industry's resistance to change.
Pulp pollution remains a serious problem. The pulp and paper industry is one of the largest and most polluting industries in the world; it is the third most polluting industry in North America.
There are about 500 kraft mills, and many thousands of other types of pulp and paper mills, in the world. Primary concerns include the use of chlorine-based bleaches and resultant toxic emissions to air, water, and soil. With global annual growth forecast at 2.5%, the industry and its negative impacts could double by 2025. While society needs paper products, we also need to move to sustainable, environmentally safe production.
Why Does Pulp Pollution Matter?
Pulp and paper is the third largest industrial polluter to air, water, and land in both Canada and the United States, and releases well over a hundred million kg of toxic pollution each year (National Pollutant Release Inventory, 1996).
In 1995, the Canadian industry said it spent close to $1 billion for environmental protection, largely to comply with environmental regulations. What industry did not say is that this money also financed expansion.
Pulp mills are voracious water users. Their consumption of fresh water can seriously harm habitat near mills, reduce water levels necessary for fish, and alter water temperature, a critical environmental factor for fish. Mill owners say they are unable to institute water conservation and recycling because the concentrated effluent would kill fish (COFI Pollution Prevention Workshop, June 1997).
In BC, 17 kraft mills discharge about 641 billion litres (141 billion gallons) of liquid effluent each year (Environment Canada, Environmental Effects Monitoring Report). While this liquid effluent is much less toxic than it was 10 years ago, "accidents" still kill test fish at one or two BC mills nearly every month. Even after the pollution control investments of the mid-1990s, the Fraser River, BC's largest watershed and one of the best wild salmon rivers in the world, is still 1% pulp mill effluent for 600 km during winter low water!
Mill waste water continues to wreak havoc on surrounding ecosystems. In laboratory tests, mill effluent causes reproductive impairment in zooplankton, invertebrates (both these are food for fish), and shellfish, and genetic damage and immune system reactions in fish (EEM Cycle One; Easton et al. 1997, Genetic Toxicity of Pulp Mill Effluent on Juvenile Chinook Salmon (Onchorhynchus shawytscha) Using Flow Cytometry, Elsevier Science Ltd., Vol. 35, #2-3).
Air pollution from pulp mills is not well studied. Mills should be, but usually are not, monitored for a range of air emissions, such as particulate matter, carbon dioxide, sulphur dioxide, hydrogen sulphide, volatile organic compounds, chlorine, chloroform, and chlorine dioxide. Incomplete data from BC's Environment Ministry indicates that in 1997, BC mills emitted 17,000 tonnes (t) of particulates and 2.7 million t of carbon dioxide, plus other unreported emissions.
Air discharges from pulp mills contain hormone-disrupting and carcinogenic chemicals, such as chlorinated phenols, polycyclic aromatic hydrocarbons (PAHs), and VOCs. BC's coastal pulp mills are the largest provincial source of airborne dioxins and furans, which are among the most carcinogenic substances known.
Sludge, the Triple Threat
Each Canadian mill produces an average 40 oven-dry t of sludge per day, which is de-watered and then either landfilled or burned. Each year, BC mills create over half a million t of sludge from secondary treatment plants, power boiler ash, chemical processing, waste fibre, sawmills, and other sources. Because of the different disposal methods, sludge pollutes soil, air, and water.
Many mills in Canada currently burn their sludge, but are eager to spread it on forests, parks, and farm lands as "fertilizer." Recently, a multi-stakeholder committee in BC explored criteria for land spreading, but the Council of Forest Industries withdrew from the committee when it was agreed that rigorous testing would be required before permitting this practice.
What Laws Control Pulp Mill Pollution?
The Canadian federal government regulates dioxins and furans, as well as other human health and fisheries-related contaminants, in mill effluent. The province of BC passed its Zero AOX law in 1992, (recinded in 2002) which required the elimination of organochlorines (AOX) by 2002. These laws deal exclusively with liquid waste. Emissions to air and land are dealt with by individual mill permits. There are no legally binding Canadian federal or provincial regulations for air emissions from pulp mills, for indoor air quality (except for Workers' Compensation Board regulations), or for ambient air quality. Solid waste landfills in BC are permitted by Ministry of Environment regional managers under the Special Waste Regulation of the Waste Management Act. Numerous loopholes and inadequacies exist in this legislation.
Compliance to all laws and regulations is largely reliant on self-reporting by the mills. Enforcement, particularly in recent years, appears to be negligible.
The Agreement on the Administration of Federal and Provincial Legislation for the Control of Liquid Effluents from Pulp and Paper Mills in the Province of British Columbia was signed in September 1994 and expired March 31, 1996. It was supposed to "harmonize" federal and provincial pulp mill effluent regulations. No concrete standards or clear policies were developed, and no staff were designated to carry out testing, reporting, inspections, or enforcement. This harmonization agreement actually resulted in less effective government monitoring and enforcement. Brian Emmett, Commissioner of the Environment and Sustainable Development in the Office of the Auditor General of Canada, recently evaluated the Harmonisation Agreement and concluded:
Pulp and paper is one of the world's largest industries, producing 178 million t of pulp, 278 million t of paper and paperboard, and consuming 670 million t of pulpwood. Growth for the next decade is expected to be between 2% and 3.5% annually, which would require an increase in logging of 1 to 2 million hectares of forest a year.
Fast-growing plantations in the Pacific Rim and Latin America are expected to provide most of this fibre. New Asia Pacific pulp mills can supply good quality pulp about one-third cheaper than BC mills, especially BC coastal mills, due to lower costs of fibre and shipping, and because of international currency exchange rates. Another factor reducing our competitiveness is that Canada's mills are essentially old and inefficient. Waste and inefficiency are two additional reasons we are losing market competitiveness.
Exports Drive the Pulp Industry
Canada is the world's largest forest products exporter, with all exports worth about $39 billion. British Columbia has the mill capacity (4.8 million t) to supply over 20% of all the northern bleached softwood kraft pulp (the highest grade) on the world market. In BC, about two-thirds of production is geared to "kraft," the other third is mechanical pulp.
Nearly all of this is exported as a base commodity instead of being converted into value-added products. This situation makes the Canadian industry extremely vulnerable to global market fluctuations, such as the recent "Asian Flu."
Until recently, BC had an edge because our pulp was made largely from old-growth fir (primarily waste from saw logs), which is very strong and in high demand. Now, however, old-growth is running out, and it is neither economically nor environmentally sound to turn it into pulp.
In addition, new technologies and wood mixtures in other countries make our pulp neither special nor price-competitive. On top of running out of a free ride on old-growth and facing tough competition in the Pacific Rim, integration and mergers are changing the industry globally and reducing the profits from "free market" sale of BC pulp.
Although the US makes a lot more pulp, it consumes almost all of it domestically. Canada, with about one-quarter as many mills, sells 90% of its pulp and newsprint on the world market. Because Canadian pulp and paper are export products, they are sensitive to global economic trends and environmental issues. This is a strong incentive for Canada to be a leader in market diversification and development.
By increasing value-added paper production and developing TCF markets, particularly in the US, which doesn't have surplus pulp, we could compensate for other market factors. In fact, modernizing our mills and developing TCF markets are primary ways to build a stable, long-term pulp and paper industry in Canada and in BC. Because of the rising public appreciation, not to mention demand, for environmental considerations, Zero AOX and Zero Discharge are the keys to the future of this industry.
We support a pulp industry with a clean, healthy environment and safe, sustainable jobs.
We have done extensive research on how to make that happen. Here is what we found:
Extensive scientific evidence supports our conclusion that oxygen-based bleaching is safest for workers, communities, and the environment.
There are a variety of reasons why pulp companies resist laws requiring TCF closed-loop mills.
The main reason is money. Preventing pollution can cost more up front, even though it benefits workers, communities, and shareholders in the long run. Other common reasons for resistance include:
Worried communities and workers ask: "Won't companies close down mills?"
This is the third time BC's pulp industry has claimed pollution laws would cause closure of every mill in the province.
Instead, the industry has had some of its most profitable years in decades. We cannot let over-simplistic arguments or job loss fear-mongering steer us off course or reduce our expectations for increased worker health and safety and much-needed environmental improvements.
A Bit of Background
In the 1980s and early 1990s, BC experienced shellfish harvesting closures because of pollution by dioxins and furans.
Dioxins and furans are highly toxic organochlorines produced when chlorine compounds are used to bleach pulp. These deadly chemicals were found in high concentrations near coastal communities having pulp mills (Powell River, Squamish, Duncan, Nanaimo, and Campbell River).
In 1992, after five years of intensive organising by workers and citizens, British Columbia passed one of its most important pieces of environmental legislation: the Pulp Mill and Pulp and Paper Mill Liquid Effluent Control Regulation, also known as the "Zero AOX" law.
The law gave mills 10 years to eliminate organochlorines (AOX) from their liquid effluent.
The second stage requires that there be no organochlorines (Zero AOX) in mill effluent by 2002. So far, only seven of BC's 26 mills appear to be able or willing to meet this goal.
The seven complying mills are either kraft mills that never used any bleach or they are mechanical mills that make newsprint (RFU! Charts, 1999, in Pulp & Paper Mills in BC, COFI/EC-EEM).
Today, about three years from the deadline, industry has stalled at around 0.7 kg/adt AOX and is pressuring government to do away with the Zero AOX requirement.
We Still Have A Long Way To Go!
BC's pulp mills have cleaned up a lot in the past decade, but they were among North America's dirtiest mills when environmental legislation forced the change.
Despite improvements, BC's pulp and paper mills still:
Pulp mill pollution continues to affect our environment in the following ways:
BC's Zero-AOX law has enabled tremendous strides toward reducing environmental and health damage from pulp and paper mill pollution. Even so, soil, water, sediments, and human and animal tissues are still contaminated with persistent organochlorines from past and current releases (Dioxins and Furans Canada-Wide Standards Development Committee, 1999).
In order to eventually rid our environment and the food chain of these toxic chemicals, we must ensure government continues with the timetable and does not back down on the goal of Zero AOX by 2002.
Why Should We Care About AOX?
We should care about AOX in our environment because many organochlorines have been shown to have toxic effects. Remember, only a small number of AOX compounds have been tested. Organochlorines are a significant component of effluent from pulp mills that still use chlorine compounds for bleaching.
Many organochlorines have been linked to health problems, such as cancer, birth defects, endometriosis, low sperm counts, and impaired foetal development. Organochlorines have also been shown to cause genetic damage and low survival rates of salmon and other fish. Organochlorines can last a long time in the environment (they are persistent) and build up in soils and animal, including human, tissues (they bioaccumulate).
Eliminating pollution from organochlorines is an important way to protect our health and the environment.
Why Do We Need Zero AOX?
We need Zero AOX because organochlorines can be toxic at levels below standard test measurements. The only sure way to protect ourselves and our environment is to eliminate the use of the chlorine-based chemicals at the source.
AOX is a good indicator of technological advancement. Because of the improvements required to eliminate AOX, mills achieving Zero AOX are among the most technologically advanced. They make efficient use of energy, water, and other resources. World-wide, mills capable of Zero AOX are also those mills capable of extremely low or Zero Discharge (closed-loop recycling) of their liquid wastes. Lower AOX measurements indicate that money and effort have been invested in pollution prevention and efficient production.
Here are some of the great things the pulp industry could accomplish if it stopped using all forms of chlorine:
TCF Markets - The Solution
The Myth That Won't Die: "There's No Totally Chlorine-Free Market"
The quickest and easiest way for BC mills to meet the 2002 Zero AOX target is to switch to Totally Chlorine-Free (TCF) production. If they do, will there be a market for chlorine-free pulp and paper?
The fact that manufacturers of pulp bleached with chlorine dioxide bill it as Elemental Chlorine Free (ECF)--along with our own market research--tells us that there is a market. Many paper buyers, from individuals to institutions, think ECF means all chlorine chemicals have been eliminated! The words chlorine-free, even when misused in this way, are a clear attraction for consumers. TCF pulp is "The Wave of the Future."
The explosive growth of Totally Chlorine Free (TCF) pulp has slowed, but not before gaining close to 25% of European sales in less than a decade (CFPA Today, Spring 1999). Sales are currently greatest in Germany, Scandinavia, and England. The companies producing TCF pulp are the only ones that have increased European market share while the pulp market there has otherwise been stagnant.
World market for TCF hardwood and softwood pulp and paper of all types is about 5 million t, 6% of a global market of 78.5 million t in 1998. Half of this TCF pulp is produced in Sweden, where TCF is 40% of total pulp production. Sweden's Sodra Cell is the world's largest producer of TCF pulp and it is expanding TCF production by another 250,000 t in 1999.
Sodra's Monsteras mill has just undergone massive expansion and has agreed to meet some of the toughest pollution permit levels in the world. The company was partly driven into TCF by regulation. "In Sweden you can only get a permit to expand your mill if you can increase output without any incremental increase in effluent. We couldn't turn back on TCF now..." (Papermaker, April 1999). (TCF is alive and well and living in Scandinavia.)
When BC's mills could not meet the environmental standards demanded by European consumers, they shifted to Asian markets. As a result, BC mills and communities suffered greatly during the Asian financial crisis.
The Customers are Lining Up
There has been no serious effort by the pulp industry to develop North American markets for TCF products. Yet our research shows that North America is an important place for niche markets that can sustain BC pulp and paper in a world where competitiveness on price alone is in serious doubt.
While industry likes to claim there is no market for TCF pulp, we have found a waiting market, frustrated by a lack of available products. A significant number of US cities, states, and companies have purchasing policies that give preference to TCF paper products. These committed customers-in-waiting include the cities of Chicago and Seattle; the state governments of Maine, Minnesota, Oregon, and Vermont; universities; credit unions; and companies like Kinko's, IKEA, and McDonald's (contact Reach for Unbleached! for a current list).
BC's mills could supply these products and further develop these markets. The market advantage would not only protect our environment and economy, it would enable industry to comply with the Zero AOX law.
Totally Chlorine Free, Zero Discharge pulp and paper mills can support a healthier environment and a vibrant, diversified economy.
Pulp mill pollution continues to harm our health and the environment. Alternative production methods exist that will eliminate organochlorine pollution (Zero AOX) and lead to Zero Discharge, further protecting our precious oceans and fresh water. Alternative markets exist that will provide stability to the Canadian pulp industry in a competitive world.
Our governments need to enforce existing legislation and promote a modern, sustainable pulp and paper industry.
