Most Of A Product's Footprint Is Locked In At The Drawing
How to cut material, energy, and emissions while the design can still change
Get each new sustainable engineering article from our team by email.
These articles show how LCA and sustainable design work on real engineering projects. We look at where a product’s material, energy, and emissions impact comes from. We show which design choices change it most. And we cover how emissions control and capture equipment is engineered. Each one starts from an engineering decision, not a slogan.
PPS engineers write these sustainability insights from design and equipment work we do. Use them to scope a life cycle study, to compare design options on more than cost, or to prepare for a customer’s sustainability questions. When a compliance deadline is close, have the equipment design checked early.
One design moves through all seven topics. Simulation checks it, best practices shape it, and methodology proves the model matches the part. Manufacturing and sustainability set its cost and footprint. Leadership and project management keep each decision on time.
A useful LCA starts with one product and one question. Compare two materials, two suppliers, or the current design against a redesign. A narrow question gives an answer your team can act on.
We map raw material, manufacturing, use, and end of life for that product. Then we gather the data you already have: bill of materials, part weights, process energy, and scrap rates.
In most engineered products, a few parts and processes drive most of the impact. A screening study finds them, so effort goes where it changes the result.
Design changes are checked in analysis before anything is cut. Then the impact is measured again, so the savings are real and the part still meets its loads and life.
Standards behind these articles: ISO 14040 (LCA principles and framework), ISO 14044 (LCA requirements and guidelines), and the EPA ethylene oxide standards for sterilization facilities.
Design out material, energy, and waste early, when the change costs least and lasts for the product's life.
Less waste by design.

Who Writes These Articles, And Where Do The Methods Come From?
Engineers write every life cycle assessment article on this page. The people who run PPS projects write about problems they see in real designs. They cover what went wrong, how they checked it, and what they would do next time. The articles teach methods, not sales pitches.
Claims from people who have never designed a part are easy to find and hard to trust. So each post names its author and shows when it was last updated. Nick Duff, Co-Founder & Chairman, CEO, is an aerospace stress engineer on flight-critical aerospace and defense programs. Tom Cushing, Co-Founder & CTO, is a licensed Professional Engineer (PE).
Tom leads the tools, methods, and design QC our engineers use from assessment to delivery. PPS engineers run FEA, CFD, CAD, and DFMA in-house. Every design goes through that QC, and the articles follow the same methods. You can read their full backgrounds on our About page. If something in an article does not match your own project, tell us and we will check. We reply within one business day.
Can I Use The Methods In These Articles On My Own Designs?
Yes. Each life cycle assessment article explains the method step by step, so you can apply it to your own design today. It covers what to set up, what to check, and what a good result looks like. We write for practicing engineers and the managers who lead them.
There is a limit, though. An article cannot see your loads, materials, suppliers, or drawings. The same method can mislead you when the inputs are off. Even NIST's BEES tool, built on the ISO 14040 approach, is only as good as the product data behind it. When a design decision depends on the answer, get a second look.
Use the articles to scope a study, compare two designs, or answer a customer's question. Bring the hard calls to us. That is what our free assessment is for. You send the data, and an engineer who can see the whole problem reviews your project scope. You get a roadmap that shows what we would check, change, or test next, and why. We reply within one business day.
Where should an engineering team start an LCA for manufactured products?
Start a life cycle assessment with one product and one question, not the whole company at once. Pick a product that sells in volume, or one a customer is asking about. Then decide what to compare: two materials, two suppliers, or the current design against a redesign.
A study that tries to cover everything stalls in data gathering and answers nothing. The EPA's life cycle view spans every stage, from raw materials and manufacturing to use and end of life. That is a lot of data. So the scope has to be narrow enough for your team to act on the result.
Map those stages for the one product, using data you already have: the bill of materials, part weights, process energy, and scrap rates. In most engineered products, a few parts and processes drive most of the impact. A screening study finds them, so effort goes where it changes the design. If a customer is asking now, send us the product data and the question. We reply within one business day.
