Wish You Enough: Looking Ahead to 2022

Do you know The Fabulous Thunderbirds? They describe themselves as “a quintessential American band.” They have been performing their “distinctive and powerful sound” since 1974. One of my favorite songs is “Tuff Enuff.” The “enough” theme is the focus of my blog looking back at 2021 and looking ahead to 2022.

The word “enough” has many different meanings in the English language. It generally means “equal to what is needed” or, in more detail, “occurring in such quantity, quality, or scope as to fully meet demands, needs, or expectations.”  Other languages have their own words for enough:  suficiente, bastante, assez, suffisamment, genug, ausreichend, abbastanza, sufficientemente, 足り, 足够的.

As I think back to 2021, first, I cannot thank my all new clients “enough.” Clients both in the US and Europe have helped me successfully launch my consulting company, Perlmutter & Idea Development. It has been very exciting to provide guidance and assistance, and I look forward to expanding in 2022. Though, thankfully, I’ll know when enough is enough and not do as the song says of working “twenty-four hours, seven days a week.”

You are Enough: Let's Look Forward

We've all had "enough” of the pandemic too. I look forward to travelling more in 2022. With the necessary precautions, business and tourist travel should expand once again. I was at CPhI-Milan in November with one of my clients, and loved being onsite. There were 170 participant countries, 1,400 exhibiting companies and more than 50 online conferences & activities. To meet our customers, partners, and friends again, and face-to-face, was a real breath of fresh air!

I believe that 2022 holds “enough” promise to open up again to new opportunities. We may have been holding off before, but we are getting to a place now where we can each realize our personal and business potential and grow together. Let us let go of what no longer serves us and check-in with our goals and objectives. Instead of getting caught up in one particular narrative, I hope to take 2022 in its entirety to satisfy and go beyond expectations.

Please keep reading my blog and my LinkedIn posts and let me know your ideas. Let me know what you anticipate when looking ahead to 2022. I am optimistic for the future and look forward to more than “enough” innovation, creativity, and community to make us stronger in 2022 and the years to come.

Circular Economy and Sustainable Travel to St Kitts 

St Kitts coastline

I have been recently writing again about the circular economy. My readers may remember by blog about  the Beer Industry and Sustainable Water with a Cherry Stout. Well, as much as I like a cold beer, I also like to practice yoga and run on the beach. With this in mind, let’s look at how one Caribbean nation is changing to renewable energy.

First, some background. St Kitts and Nevis is a tropical two-island country in the eastern Caribbean Sea. Both of the mountainous islands were formed by volcanic activity. St Kitts is a fertile island with mainly black sandy beaches. Nevis is surrounded by coral reefs and has silver beaches. The area is well-known for its lava formations, tropical forests and lagoons and the underwater marvels seen while snorkeling or diving.

OK, that’s enough being a travel agent. What I really want to talk about is the nation’s solar-plus storage project, which upon completion, is expected to eliminate 41,500 metric tonnes of carbon emissions in its first year. The endeavor is in keeping with the nation's participation in a United Nations Environmental Program for a Regional Coalition on a Circular Economy. It helps the nation pursue a resilient, diverse, and inclusive economic model that creates opportunities for a sustainable growth and moves away from a ‘take, make, waste’ mentality.

About the Solar-Plus Storage Project

The Solar-Plus Storage Project is a “significant milestone” for the region, helping to create a more independent energy market and reduce reliance on fossil fuels.  It is a $70 million solar and storage microgrid project by Swiss company Leclanché.

The project is a fully integrated system consisting of three core components: a 35.7-MW solar photovoltaic system (the solar field), a 14.8-MW/45.7-MWh lithium-ion battery energy storage system (BESS), and Leclanché’s proprietary energy management system (EMS) software.  When completed, it is expected to provide between 30% and 35% of the island’s baseload energy needs for the next 20 to 25 years.

A portion of the generated electricity will meet the island’s daily peak power demand, yet I’m particularly interested in the system’s battery storage. Housed in 14 custom-designed enclosures near the state-owned utility St Kitts Electric Company (SKELEC)’s main power station and adjacent to the solar field, the large-scale BESS makes it possible to meet peak demand after the sun sets.

Once completed the solar and storage system is predicted to replace more than four million gallons of diesel fuel per year. It is expected to generate about 61,300 MWh of electricity in its first year. Finally, the system is to reduce carbon dioxide emissions by nearly three-quarters of a million metric tons over 20 years.

 

Sustainability in the Circular Economy

It is great to see this project in the works and due to be completed by mid-2022. Leclanché CEO Anil Srivastava has said that the build “sends a strong signal to other Caribbean countries…that there is a cleaner, more cost-efficient and viable alternative to diesel power.”

Certainly, power generators around the region will be looking at the results. Recently, a group of Caribbean and Latin American states, including the Dominican Republic and Haiti, committed to ensure an average 70% of installed energy capacity comes from renewable sources by 2030.

I’m sure, like me, you’d be willing to work remotely in the Caribbean to see how this example of the circular economy plays out. Then, our tourist dollars are supporting a sustainable environment too!

Let’s work to sell this concept! Just as we need to continue to sell the circular economy model in all that we do. See you in the Caribbean in late 2022.

Circular Economy and Closing the Loop in Case Studies

Recently I blogged about how to address Circular Economy considerations in engineering and applied science settings and how companies too can learn to adapt. It is fast becoming a necessity as industry recognizes the criticality of a holistic approach to sustainability. For example, the UK last year announced £22.5m in government funding for five new R&D centers focusing on the circular economy and developing methods to reuse and recover materials that would ordinarily become waste.

Drawing on my interest in embracing the circular economy approach, I have collaborated again with Professor Ugur Tuzun of the University of Cambridge. Our recent Journal of Chemical Engineering & Process article is entitled Cradle to Cradle Systems Analysis for Chemical and Biological Engineers: The Role of Progressive Sampling in Possibility Envelope for Value Added Manufacturing Design and Chemical Process Applications.” 

The article discusses holistic systems interactions using two specific industrial case studies. The potential interactive teaching tools explore a mathematical framework of the principles of holistic systems interactions. At the same time, the article suggests industrial case studies play an increasingly important role in the teaching of systems engineering and sustainability within an industrial ecological framework utilizing metacognitive and experiential learning principles.

Closing the Loop in Holistic Approach to Sustainability

Each individual case study in the article makes use of the “closed loop” optimization of material and energy inflows and outflows to minimize waste and harmful environmental emissions. The attainment of the “closed loop” is achieved by facilitating successive progressive stages of materials and energy recovery and re-processing coupled with the re-utilization and regeneration of intermediate byproducts and waste from each successive processing stage. Available options to minimize harmful environmental impacts are explored by progressive sampling within the possibility envelope.

Via this experiential approach to teaching, the learner (student or operating company) is asked to demonstrate the systematic process of “narrowing down” options and choices through a decision-making process starting off with the lead activity lifecycle, which defines the outermost boundary of the possibility envelope. The scope of all possible actions and consequences is explored and reduced successively by the introduction and consideration of all other life cycles; progressing along a decision pathway that updates and integrates the considerations made under each of the materials and energy life cycles.

This is a valuable way of approaching decision-making, and students and operators can both benefit from this exercise of whittling their choices and weighing possible results. Read the entire article online to learn more about tackling sustainability issues in a holistic manner.  Professor Tuzun and I would welcome the opportunity to assist you.  Please reach out to us.

Teaching & Learning in the Circular Economy

 

Since the industrial revolution there have been waves of technology and innovation.  We all remember the movie “The Graduate” and that technology wave told to Dustin Hoffman in one word: PLASTICS.  The next wave came along in the chemical/petrochemical and pharmaceutical industries.  It also brought along the US Environmental Protection Agency, where, as many of you know, my career began.  Now, we all see the next wave coming with the Circular Economy.

What does this mean?  The three main areas considered in the circular economy are:

  1. Reusing the waste material generated as raw material or feedstock for the next process
  2. Feedstock substitution where plant based, and biomass substituting for petroleum-based products
  3. Changing the energy sources to renewable sources.

There are many, many articles written on these subjects. What interests me is how to teach these subjects so students and companies can effectively learn about the circular economy.

I collaborated recently with Professor Ugur Tuzun of the University of Cambridge on a Journal of Chemical Engineering & Process article entitled Self-Evaluation of Industrial Case Studies with Iterative Improvements to Support Chemical and Biological Systems Engineering and Sustainability Teaching and Learning.”

 Education around Circular Economy

Industrial case studies play an increasingly important role in the teaching of systems engineering and sustainability within an industrial ecological framework employing metacognitive and experiential learning principles. The principal classroom teaching tool of experiential learning, case studies develop student self-awareness and self-evaluation skills while they focus on providing optimal solutions to challenges provided by the industrial examples. The learning process here relies on students attempting iterative improvements to the industrial processes and plant operations. They work with a view to create a “best fit”: efficiently using resources at hand, aware of the specific ecological setting, and considering circular economy constraints regarding recycle, re-use, and regeneration of resources.

The Tuzun article shares two alternative approaches of iterative case study evaluations as well:

  1. Relying on the “bottom-up” approach to systems identification and development to enable the use of new material and energy resources
  2. Taking a “top-down” approach to evaluate and improve an existing system of complex and integrated process plant operations.

In each case, the student is challenged with complex issues and the self-learning and evaluation process requires the necessary deepening of the skills of core engineering and applied sciences.  The additional benefit of this student-centered approach to teaching and learning is the draw upon core scientific and engineering science in a “hands-on” manner as opposed to a more classic passive learning through lectures.

Our field is always adapting. This article is part of the process. While the journal article focuses on students, my hypothesis is that these approaches can also be applied within an operating company to address sustainability issues in a holistic manner.  Professor Tuzun and I would welcome the opportunity to assist you.  Please reach out to us.

Ebook Explores Automated Filtration Technologies for Clarification Applications

automated filtration technologies

Over my almost 40 years in the process industry, many people have helped me along the way. Having opened my own consulting business, Perlmutter & Idea Development, I thought it time to give back to the engineering and process communities. Earlier this year I taught a short course in the American Filtration Separations Society Learning Center, “Automatic Filtration Technologies.” This month, I have released a related e-book, Framework for Selecting Automated Solid-Liquid Filtration Technologies for Clarification Applications.

This e-book is the first-of-its-kind specifically for the process industries. Based on my experiences, and my collaborations with other process experts, this book provides in-depth treatment of possibilities to automate the clarification processes to improve filtration while minimizing operator exposure.

Understanding Clarification Systems

A clarification system is employed after coarse-particle filtration or as a stand-alone system to remove fine particles at low concentrations. These particles are typically less than five microns (μm) and are in concentrations less than five percent solids down to ppm levels. Engineers can evaluate several types of automated, pressure-filtration, clarification technologies. The cake solids structure and the nature of the process determine which type of clarification system is appropriate for an application.

Framework for Selecting Automated Solid-Liquid Filtration Technologies for Clarification Applications:

  • Characterizes slurries
  • Discusses filtration lab testing
  • Differentiates between candle filters, circular plate filters, concentrating candle filters
  • Explores filter media and filter aid options
  • Shares case studies from the specialty chemical industry (resins, zeolites and pharmaceutical)

Practical Applications of Automatic Filtration Technology

I’ve encountered some interesting approaches to solid-liquid separation processes. In one case, I was at a melamine resin facility where the slurry was in a formaldehyde process. The operators were wearing “masks” opening up a manual plate filter in a room with residential floor fans to dig out the cake from the paper filter media. In another case, for zeolites, the client had multiple bag filters to clarify the filtrates following a vacuum belt filter. When the final product remained cloudy,
to my surprise, the client decided to add another set of bag filters.

You probably have your own examples of process engineers struggling to clarify process liquids. The Framework for Selecting Automated Solid-Liquid Filtration Technologies for Clarification Applications  presents actual case histories to illustrate problems and improved installations with automatic filtration.
