Pollution Engineering, 34(4), 16-19. Unit Lesson Nice job progressing through Units I and II. In Unit III, we'll study audits. Chapters 7 and 8 in the textbook discuss eco-audits. This lecture will teach pollution prevention audits.

An eco-audit tends to focus on reducing energy use and reducing carbon dioxide (CO2) emissions. If non-fossil energy sources are used, then CO2 emissions are automatically eliminated, and the focus is on energy reduction to conserve resources. If fossil sources are used for energy, then the challenge, though somewhat the same, moves more toward CO2 reduction, which can occur from reducing energy consumption. While eco-audits focus on reducing energy consumption and reducing CO2 emissions, the P2 audit encompasses more than energy and has an ultimate goal of source reduction. Though the Pollution Prevention Act focuses on source reduction, over the years, businesses have broadened what they consider as pollution prevention (P2).

According to Cheremisinoff (2002a): P2 is any practice that: ï‚· Reduces the amount of any hazardous substance, pollutant or contaminant reentering any waste stream or otherwise released into the environment prior to recycling, treatment and disposal. ï‚· Reduces the hazards to public health and the environment associated with the release of such substances, pollutants or contaminants. ï‚· Reduces or eliminates the creation of pollutants through increased efficiency in the use of raw materials or through protection of natural resources by conservation. (p. 24) Cheremisinoff (2002b) includes the corporate bottom line, "A P2 investment must be able to stand up to every other funding request and effectively compete for money on its own merits" (p.

16). Thus, though companies must comply with the laws listed in the Unit I lecture (often seen as costs rather than benefits to management) as they conduct their business, it behooves companies to look at P2. Not only is P2 helpful to the environment, good P2 programs benefit a company's finances. In Unit II, you were introduced to life cycle analysis (LCA). Understanding the life cycle of a product enables the P2 manager to locate P2 possibilities, such as fixing leaky pipes or using more efficient fuel sources.

The UNIT III STUDY GUIDE Pollution Prevention Audits MEE 6201, Advanced Pollution Prevention 2 UNIT x STUDY GUIDE Title textbook reading for Unit III covers eco-audits, while the supplemental readings cover P2 audits. What is the difference? An eco-audit focuses on energy use and carbon dioxide (CO2) emissions with the goal being to reduce those two quantities. While a P2 audit will locate production areas where energy usage can be reduced, it doesn't have the same focus on reducing CO2 emissions as in an eco-audit. A P2 audit looks at all types of pollution produced, excess energy used, and protection of resources.

Thus, it is broader than an eco-audit. The LCA and P2 audit tend to overlap in coverage but differ in when they are conducted. An LCA is often conducted before a process is built, while a P2 audit is conducted during operation. Cheremisinoff (2002b) outlines the elements of a P2 audit. The primary phases are: 1.

Phase I: Pre-assessment for audit preparation. 2. Phase II: The in-plant assessment. 3. Phase III: Synthesis, benchmarking, and corrective actions. (p.

17) Table 1 shows the steps within each phase of a P2 audit. Phase I: The Pre-assessment (quoted from Cheremisinoff, 2002b) Step 1 Audit Focus and Preparation Step 1.1 Get Ready Step 1.2 Assemble the Audit Team Step 1.3 Identify and Allocate Additional Resources Step 1.4 Select the Subject Facility Step 1.5 Define the Audit Objectives Step 1.6 Review Documentation Step 1.7 Gain Employee Buy-in and Participation Step 2 List the Unit Operations Step 2.1 Refine Our Initial Checklist Step 2.2 Conduct an Initial Walk-through Step 3 Constructing Process Flow Sheets Step4 Preliminary Assessment and Next Steps Phase II: The In-plant Assessment Step 5 Determining the Inputs Step 5.1 Determine the Total Inputs Step 5.2 Determine the Inputs to Unit Operations Step 5.3 Consider the Energy Inputs Step 5.4 Record Information on Process Flow Sheets Step 6 Accounting for Water Usage Step 7 Measuring Current Levels of Water Use and Recycling Step 8 Quantifying Process Outputs Step 9 Accounting for Wastewater Flows Step 9.1 Identify the Effluent Discharge Points Step 9.2 Plan and Implement a Monitoring Program Step 9.3 Reconciling Wastewater Flows Step 9.4 Determine the Concentrations of Contaminants Step 9.5 Tabulate Flows and Concentrations Step 10 Accounting for Gaseous Emissions Step 10.1 Quantify the Gaseous Emissions MEE 6201, Advanced Pollution Prevention 3 UNIT x STUDY GUIDE Title Step 10.2 Tabulate Flows and Concentrations Step 11 Accounting for Off-Site Wastes Step 12 Final Preparation for the Material-Balance System Step 13 Construct a Material Balance Information Sheet Step 14 Evaluating Material Balances Step 14.1 Classify the Material Balances Step 14.2 Determine the Gaps and Inaccuracies Step 15 Refine the Material Balances Phase III: Synthesis, Benchmarking, and Corrective Actions Step 16 Low-cost/No-cost Recommendations Step 17 Targeting and Characterizing Problem Wastes Step 18 Segregation Step 19 Developing Long-Term Waste-reduction Options Step 20 Environmental and Economic Evaluation of P2 Options Step 21 Developing and Implementing the Action Plan (p.

17) Table 1 is a good outline of a P2 audit. Specific industries or processes may have other steps, however. Several sections of the audit will be presented as examples. As an example, consider a fictitious company called ALref that refines aluminum. Recall from Unit II that a refinery separates aluminum oxide from bauxite rock and creates alumina.

Alumina chemically is Al2O3 and looks like white powder. Example of Step 1.1 Step 1.1 Get Ready: April 11, 2016: Have staff in place for audit. Begin Phase I. May 6, 2016: Have Phase I completed. May 9-20, 2016: Discuss Phase I.

Modify Phase II and III as needed. May 23, 2016: Begin Phase II. July 22, 2016: Have Phase II completed. July 25 - Aug 5, 2016: Discuss Phase II. Modify Phase III as needed.

Aug. 8, 2016: Begin Phase III. Nov. 18, 2016: Complete Phase III. Nov.

21 - Dec. 9, 2016: Discuss Phase III. Example of Step 1.7 Step 1.7 Gain Employee Buy-in and Participation: Set up incentive program for employees to report leaks, suggest where there are inefficiencies, suggest alternative energy sources, and suggest P2 opportunities that they spot. Do not chastise employees for trying to change anything. Encourage them to find and discuss possibilities for improvement.

Provide gift cards to lower-level staff who propose ideas that get implemented. Example of Step 2 (unit operations from Advameg, 2015) Step 2. Listing the Unit Operations: ï‚· Crusher: Crushes the bauxite rock. ï‚· Grinder: Adds caustic soda (sodium hydroxide NaOH) and water to the crushed rock to dissolve it and create liquid slurry containing small-sized ore particles. ï‚· Digestion: Adds additional heat and pressure to the slurry, lets it digest for an hour or so, then depressurize and reduce the temperature. Result is a mixture of suspended solids. MEE 6201, Advanced Pollution Prevention 4 UNIT x STUDY GUIDE Title ï‚· Clarification: Settles out the heavier materials which are waste products called "red mud" (sand, iron oxides and trace elements from the bauxite).

The liquid in the tanks has a consistency of coffee and is filtered. Material on the filters is aluminum oxide but is not yet the finished product. ï‚· Precipitation: The wet aluminum oxide is put in a precipitation tank where aluminum oxide crystals are added as a seed to the wet aluminum oxide. The wet aluminum oxide gathers on the seed making bigger crystals. The crystals settle out. ï‚· Calcination: The settled out crystals from the precipitation process are heated to dry them. The result is the final alumina product.

The unit operations are the key to a P2 audit since they will lead to P2 opportunities that can be listed in Phase III. As a student preparing a P2 audit for our course, you will likely have references (such as the ones listed in this lecture) due to unfamiliarity with the processes. However, as a real employee of a company preparing a P2 audit, you will be familiar with the unit operations and thus would not have references. As you move into Phase II of the P2 audit, useful information for Steps 5 ("Determining the Inputs") and 6 ("Accounting for Water Usage") can be found in Chapter 15 of our textbook. The chapter has over 100 pages of energy and water requirements to produce various products.

Example of Phase II's Step 13 Material Balance Using flow meters, measure flow rate Q1 (gpm, i.e. gallons per minute) of water into the grinding process. From stoichiometry and heat balances, determine how much water is used in the process (Q2). Measure Q3, which is the flow of water (gpm) out of the process. Ideally, Q3=Q1+Q2. If the computed Q3 and measured Q3 are different by over 10%, then look for leaks in the system.

List material balances for all processes. This lecture presents a P2 audit outline with examples of some of the sections as well. Please refer to Chapter 8 of our textbook, "Case studies: eco-audits," for examples of eco- audits. Some of the information from an eco-audit (e.g. energy usage, materials used, and water consumption) can be used in a P2 audit. The recommendations in Phase III of the P2 audit should be very specific.

As an ALref P2 manager, you will have walked around the alumina refinery numerous times, becoming very familiar with the workers and processes. That familiarity, along with math computations of material and energy balances, will provide you with knowledge of where source reduction and other P2 options can be implemented. Chapter 8 of our textbook gives very specific numbers for energy use, material quantities, water consumption, and other items. That type of detail should be in a P2 audit. Cheremisinoff (2002a) provides additional examples of P2 audits.

This lecture has contained a lot of information. You now have an idea of the aspects of a P2 audit. Now, it's time to go to work and prepare an audit! References Advameg, Inc. (2015). How products are made: Volume 5 – aluminum.

Understanding Pollution Prevention Audits

Pollution prevention audits (P2 audits) serve as an essential framework for businesses aiming to minimize waste and streamline processes while complying with environmental regulations. As highlighted in the curriculum for MEE 6201, Advanced Pollution Prevention, these audits extend beyond mere compliance with laws; they position themselves as strategic instruments in environmental management, benefiting both the ecosystem and the organization's bottom line.

The Foundations of Pollution Prevention Audits

At its core, a pollution prevention audit is a systematic assessment designed to identify opportunities to reduce hazardous substances, pollutants, and waste in processes, with the ultimate goal of source reduction. The Pollution Prevention Act defines P2 practices as those that prevent pollution at its source rather than managing it after it has been created (Cheremisinoff, 2002a). Inherent in these practices is the belief that effective pollution control can happen concurrently with operational efficiency and economic viability.
The P2 audit process can be broken down into three primary phases—pre-assessment, in-plant assessment, and synthesis/benchmarking and corrective actions—each encompassing a series of steps aimed at achieving comprehensive insight into an organization's pollution generating processes.

Phase I: Pre-Assessment for Audit Preparation

The first phase involves meticulous preparation to ensure that the audit team is well-equipped. This includes assembling a diversely-skilled team, whom Cheremisinoff (2002b) argues should include members from various departments like HSE (Health, Safety, and Environment), engineering, operations, and management to facilitate a broader perspective on potential audit findings.
1. Audit Focus and Preparation: The first step involves outlining the primary objectives of the audit. Organizations must determine which units or processes will be audited based on factors like historical pollution records, compliance issues, and stakeholder concerns (Cheremisinoff, 2002a).
2. Listing the Unit Operations: Following the definition of audit objectives, organizations should accurately identify and document all operational processes. For instance, a recycling plant might outline operations such as sorting, shredding, and material recovery to gain insight into potential inefficiencies and pollution points.

Phase II: The In-Plant Assessment

The second phase is characterized by detailed evaluations of physical processes within the identified units. This involves obtaining data on inputs, outputs, and various emissions.
1. Determining Inputs: A thorough record of all inputs such as raw materials and energy is crucial. Understanding the magnitude and nature of these inputs aids in identifying excessive consumption and potential sources of waste (Cheremisinoff, 2002b).
2. Accounting for Water Usage: Water is another significant input that requires detailed tracking—a company may find that a substantial amount of water is wasted through leaks, leading to actionable recommendations in subsequent phases (Cheremisinoff, 2002b).
3. Quantifying Outputs and Emissions: Detailed quantification of waste outputs is essential, as it forms the basis to identify where potential reductions can be made. For instance, emissions monitoring provides necessary data for compliance and can reveal the areas where technology upgrades could facilitate significant reductions in pollution.

Phase III: Synthesis, Benchmarking, and Corrective Actions

Once data collection is completed, the audit shifts toward analysis and identification of actionable strategies.
1. Developing Low-cost/No-cost Recommendations: This step emphasizes immediate changes that can reduce waste without extensive investments. For instance, simple changes like adjusting operational parameters to limit energy consumption or modifying maintenance schedules can yield significant results (Cheremisinoff, 2002b).
2. Environmental and Economic Evaluation of P2 Options: It is crucial to align potential pollution prevention options with economic benefits. Cost-saving from reduced material usage or lower disposal fees is a potent incentive for organizations to invest in P2 strategies.
3. Action Plan Development: The audit concludes with a detailed action plan that includes timelines, responsibilities, and measurable outcomes. Engaging employees by presenting them with incentives for identifying inefficiencies can lead to a culture of continuous improvement and increased participation in P2 initiatives.

Benefits of Conducting P2 Audits

The benefits of implementing pollution prevention audits extend beyond environmental compliance; they can lead to substantial financial savings and enhanced corporate image. By proactively addressing waste management and emissions, organizations not only comply with legal frameworks but also gain a competitive edge in a market increasingly focused on sustainability (Ashby, 2013).
Various case studies demonstrate that organizations implementing P2 audits have significantly reduced operational costs related to energy and waste disposal while enhancing their brand reputation by adopting sustainable practices (Advameg, 2015).

Conclusion

In conclusion, pollution prevention audits are a vital tool for any organization aiming to minimize its environmental impact while simultaneously enhancing operational efficiency. Through structured phases that promote thorough preparation, detailed assessments, and strategic planning, P2 audits empower organizations to attain sustainable practices that benefit both the bottom line and the overall environment.
