The pulp and paper industry produces some of the greatest amounts of waste across the industrial sector. This is due to the high amount of water and energy used in the production process. Each production step generates its own waste, and each one poses a unique threat to the environment, which means the reduction of pulp and paper waste is a top priority for facility managers.
Let’s take a closer look at two ways to reduce pulp and paper waste.
Method #1: Chemical Recovery and Recycling
An especially effective method for the chemical pulping process, chemical recovery and recycling can put a big dent in the reduction of pollutants and, simultaneously, can increase economic return. Because of the economic viability of the kraft process, chemical recovery is a necessary step for waste reduction — but some sulfite mills still have no recovery system in place.
Method #2: Best Available Techniques (BAT)
Another more general way to minimize waste from pulp and paper mills is by applying Best Available Techniques (BAT). These techniques come from the Integrated Pollution, Prevention and Control Regulation.
According to the IPPC, in order to have an effective waste management system, that system must reduce the following things:
- Lability
- Cost
- Regulatory burdens of hazardous waste management
If your mill’s current system accomplishes all of the above, then it’s likely that you don’t need to make any changes. However, if it is falling short in one or more areas, it would be wise to consider an alternate waste management system — or, at the very least, modifying your current system.
New Technologies: Right for Your Pulp and Paper Mill?
Sometimes, excessive waste production can be solved with the implementation of a new technology, but you will have to determine if a change like this is right for your mill. Examples of updated technologies include the following:
- Organic Solvent Pulping
- Acid Pulping
- Biopulping
- Elemental Chlorine Free (ECF) and Total Chlorine Free (TCF) Bleaching
- Biobleaching
- Extended Delignification
