Let's be honest: labs aren't famous for being environmentally friendly. From stacks of paper notebooks to forgotten reagents gathering dust, common lab practices often lead to waste and inefficiency. But here's the good news—making your lab sustainable usually means making it more efficient, too.

In this post, we'll dive into three major sustainability challenges that labs face:

• Paper clutter
• Expired reagents
• Overstuffed freezers
  

We'll provide straightforward solutions, highlighting how digital tools like Scispot can streamline these efforts. Whether you're running a biotech startup, managing an academic lab, or serving as a sustainability officer, these tips will help your lab operate smarter and greener.

The Everyday Sustainability Struggle in Labs

Expired chemicals, overflowing paperwork, and cluttered freezers—does this sound familiar? You’re not alone. Labs worldwide struggle daily with these exact issues.

Consider reagent management: one survey found that labs discard around $500 worth of expired chemicals every month, spending another $300 on waste disposal (Triumvirate.com). In fact, 20% of lab professionals say handling expired inventory is a major weekly headache. It's more than just wasteful—it's costly and hazardous. Then there’s the silent productivity killer: paper. Many labs still rely on handwritten notebooks and printed reports. Crucial data gets buried in binders, making sharing information tedious and error-prone. And let’s not forget freezer chaos. Those jam-packed -80°C freezers, holding mystery samples from years past, aren’t just frustrating to manage—they consume enormous amounts of energy. Did you know one ultra-low temperature freezer uses as much electricity as a four-person household? 

Bottom line: inefficiency and waste are closely connected. The good news is, simple changes—often digital—can significantly enhance sustainability and productivity. Let's explore how.

Tip 1: Replace Paper with Electronic Lab Notebooks (ELNs)

Is your lab bench hidden beneath stacks of notebooks, printouts, and binders? It’s time to go digital. Switching from paper to Electronic Lab Notebooks (ELNs) helps you save more than trees—it boosts efficiency, reduces errors, and simplifies data management.

Why ditch paper? Imagine needing to revisit last year's experiments. Traditional paper methods mean flipping through countless pages or deciphering faded, coffee-stained notes taped inside overloaded notebooks. Crucial information easily slips through the cracks, risking months of hard-earned data. The digital advantage: ELNs gather all your protocols, notes, and data in a single, searchable platform accessible to your entire team. Instead of spending precious time searching notebooks, you can find past experiments instantly. ELNs also let you upload and attach instrument outputs, gel images, or datasheets directly to your entries—eliminating the need for printouts and taping.

The result? Less clutter, faster communication, and clearer documentation. Sustainability meets productivity effortlessly.

How Scispot Can Help:

Scispot offers a modern, user-friendly Electronic Lab Notebook (alt-ELN) designed specifically to streamline lab documentation. Labs using Scispot have successfully transitioned to nearly paperless operations by digitizing protocols, experimental results, and approvals—all securely stored online. For example, one chemical manufacturing lab replaced fragmented paper-based workflows with Scispot’s platform. The result? A dramatic reduction in paperwork clutter and improved compliance through built-in electronic signatures and automatic audit trails. With a digital ELN, you no longer need physical printouts or manual sign-offs. Everything is automatically logged, timestamped, and searchable, making your data management simpler, faster, and significantly less wasteful.

Practical Steps to Go Paperless:

• Begin entering new experiments directly into your digital ELN, rather than on paper.
• Digitize frequently referenced historical records by scanning or photographing them.
  Encourage your team to view protocols on tablets or computers directly at the bench, reducing the need for printed copies.
  

Transitioning may feel unusual initially, but soon the ease of accessing and sharing data digitally will become second nature. Your team—and the environment—will both benefit.

Tip 2: Use Smart Inventory Management to Avoid Wasting Reagents (and Money)

Take a quick look at your chemical cabinet. How many reagents are expired or duplicated? These wasted chemicals represent a significant sustainability issue and drain your budget. Labs report discarding hundreds of dollars' worth of expired reagents monthly and paying additional costs for hazardous waste disposal (Triumvirate.com).

What causes this waste? Usually, it’s due to:

• Poor inventory tracking – forgetting what's in stock, causing unnecessary reorders.
• Bulk purchasing without accurate forecasting leads to unused stock.
• Overlooking expiration dates until it's too late.
  

This problem intensified during the COVID-19 pandemic, with labs panic-buying chemicals that later expired unused.

‍

The Solution: Implement Smarter Inventory Management

Switching to a digital inventory system helps labs drastically reduce waste. Here’s how you can quickly get started:

• Track Expiration Dates and Quantities:
  Keep an updated digital inventory (a simple spreadsheet can work initially) listing each reagent’s quantity, expiration date, and purchase date. Regularly update it after each use. This practice helps you plan experiments to use reagents efficiently before they expire and prevents unnecessary reordering.
  
  
• Set Minimum Stock Levels and Reorder Alerts:
  Define minimum quantities for critical reagents and set automated alerts to notify your team when supplies dip below these levels. This prevents last-minute shortages and helps avoid overstocking (Labmanager.com).
  
  
• Adopt the FIFO (First-In, First-Out) Approach:
  Arrange your inventory so that older reagents—those closest to expiration—are easily accessible and used first. Train your team to always pick the oldest viable stock. This simple practice greatly reduces hidden waste from forgotten reagents in the back of storage shelves.
  
  

How Scispot Helps:

Scispot simplifies inventory management through an intuitive, automated platform called Labsheets. With Labsheets, labs can effortlessly:

• Record and monitor reagents with details like lot numbers, expiration dates, and quantities.
• Receive timely email or in-app notifications when inventory runs low or when reagents are nearing expiration.
• Automatically link reagent usage directly to experiments logged in the Electronic Lab Notebook (ELN), instantly updating inventory without extra manual steps.
  

One biotech company that adopted Scispot’s inventory management reduced its inventory maintenance time by 80% and completely eliminated stockouts. The result? Far less waste, fewer unnecessary purchases, and significant cost savings.

Tip 3: Centralize Lab Purchases to Prevent Double-Ordering

Have you ever received a delivery and realized someone else ordered the exact same reagent just last week? Double-ordering is a common frustration in busy labs, wasting budget and causing supplies to expire unused on the shelf. To tackle this issue, centralize purchasing and improve communication around ordering. Pairing this strategy with smart inventory tracking (Tip 2) ensures everyone is on the same page.

Practical steps to eliminate duplicate orders:

• Implement a Shared Ordering System:
  Use a shared spreadsheet or platform to log supply requests and orders. When someone orders an item, mark it clearly so the whole team is informed and can avoid duplicate purchases.
• Designate an Inventory Coordinator:
  Assign one team member (or rotate the responsibility) to oversee orders. This person acts as a gatekeeper, approving purchases and ensuring orders match current inventory needs.
• Integrate Inventory with Purchasing Software:
  Modern inventory software can link directly to purchasing platforms. When inventory reaches a minimum level, the system automatically triggers a reorder, which is visible to the entire team. This integration helps streamline ordering and reduces reliance on scattered emails and notes.
  
  

How Scispot Helps:

Scispot simplifies purchasing by seamlessly integrating with lab supply platforms such as Quartzy. When a reagent falls below the defined inventory threshold, Scispot automatically adds it to your Quartzy order list. After ordering, Scispot updates inventory levels and notifies your team, clearly indicating the item's status. This prevents redundant purchases and keeps stock levels efficient, saving your lab money and minimizing waste from expired surplus supplies.

Even without sophisticated tools, promoting a simple culture of “check before you order” can dramatically reduce waste. Before placing an order, quickly verify your existing inventory—it might save your lab from another forgotten reagent in the fridge. Small habits like this foster a more efficient, sustainable lab environment over time.

Tip 4: Optimize Your Freezer Storage to Cut Waste and Energy Use

Take a peek inside your lab’s freezer—chances are you’ll find plenty of forgotten samples. Unlabeled tubes, remnants of old projects, or mystery boxes from former team members can quickly accumulate. An overcrowded freezer doesn't just waste valuable space; it consumes significant energy. In fact, one ultra-low temperature (-80°C) freezer can use as much electricity as an average family home (FreezerChallenge.org). Keeping unnecessary samples means you're wasting energy—and money. Optimizing freezer use not only makes your lab more sustainable, it also improves overall efficiency.

‍

Practical Steps for Better Freezer Management:

• Schedule Regular "Freezer Clean-out" Days:
  Once or twice a year, dedicate time to sorting your freezer contents. Dispose of expired samples or those from completed projects following appropriate protocols. Consider combining cleanup days with lab meetings or events (free pizza usually helps!). Labs participating in MIT’s Freezer Challenge collectively saved over 86,000 metric tons of greenhouse gases and nearly $17,000 in energy costs simply by optimizing freezer storage (MIT Sustainability).
  
  
• Maintain an Updated Freezer Inventory:
  It may seem basic, but many labs neglect keeping track of freezer contents. Create a simple, detailed inventory organized by freezer, shelf, rack, or box. This practice prevents duplication ("Did someone already make that aliquot?") and identifies old, unnecessary samples. Proper inventory saves time, avoids waste, and reduces redundant storage.
  
  
• Clearly Label and Organize Samples:
  Use durable, frost-proof labels for all samples and boxes, grouping similar samples together. Clear labeling reduces the time your freezer door stays open during searches, saving energy and preventing temperature fluctuations. Good organization also gives confidence to safely discard unused or expired samples.
  
  

How Scispot Helps:

Scispot provides intuitive freezer management tools that digitally map samples directly to storage locations. Instead of relying on spreadsheets or memory, you can quickly log and track each sample's metadata—such as type, creation date, and precise freezer location.

For example, searching for last summer’s DNA aliquot? A simple query in Scispot instantly points you to Freezer 2, Rack B, Box 3. When samples are disposed of or moved, updating records takes seconds, promoting consistent cleanliness and organization. Labs using Scispot often implement QR-code or barcode scanning, further simplifying inventory management and reducing manual errors. As highlighted by the International Freezer Challenge, a digital, up-to-date inventory is crucial for reducing the number of freezers needed, saving significant energy costs, and improving sustainability (FreezerChallenge.org).

Remember, a tidy and well-managed freezer isn’t just environmentally friendly—it also boosts scientific productivity. Less time hunting through mystery tubes means more time for actual research, fewer repeated experiments, and happier, more efficient lab teams.
