Labs play an essential role in advancing sustainability in the wider world but they need to tackle their own levels of waste and consumption. Graham Matthews provides a simple checklist for improvements.
Laboratories stand at the forefront of innovation and discovery. However, the work within these vital research facilities often comes with a significant environmental footprint. This is led by high energy consumption and the large amounts of clinical waste they produce.
Most labs should aim to redefine their operational practices towards a more sustainable way of running but also for greater efficiencies andreduced costs. They have an intensive resource use and therefore have a unique opportunity to lead by example and make a positive change.
Sustainability and waste experts from the company Business Waste share six strategies for reducing energy consumption and waste:
Auditing
An energy audit is the first step in transitioning towards a more effective way of energy use in any laboratory. It involves a detailed assessment of the lab’s current energy consumption, identifying which processes consume the most energy and pinpointing areas for improvement.
Experts employ special tools to accurately gauge energy consumption throughout various parts of the laboratory, ranging from HVAC systems to specific pieces of equipment. This audit establishes a reference point, enabling the assessment of the impact and efficiency of future renewable energy projects.
Identifying energy efficient alternatives
Following your energy audit, try to spot the biggest sources of energy consumption and see if there are more effective alternatives on the market. For instance, energy efficient equipment, such as autoclaves and fume hoods, will significantly reduce electricity consumption, while air-cooled condensers will minimise water usage.
Consider switching to programmable thermostats that create automatic temperature adjustments based on the time of day and the occupancy. This will ensure that the heating is never left on outside of working hours and the temperature is always optimised. Alternative heating options include radiant heating systems or heat recovery ventilators – both of these are great options for better energy consumption.
Sustainability and energy efficiency in the laboratory starts with the people who work there
Secondly, look at the lighting. LED lights are the first option the laboratory management team should consider. Not only do they drastically reduce energy consumption, but they also have a longer lifespan than most lighting systems. Occupancy sensors are also a strong alternative as they ensure the light is never left on – they immediately switch off when movement isn’t detected.
Feasibility studies
After the easier switches, a feasibility study assesses whether renewable energy solutions are achievable for each specific laboratory’s location and infrastructure. This study should look into several factors – geographic location, climate conditions, local regulations and the physical characteristics of the laboratory site. For example, for solar energy, factors like roof orientation, shading and structural capacity need to be examined. For wind energy, wind speed and consistency are the key factors that will determine if this energy substitute can be deployed. The feasibility study helps to identify the most viable renewable energy solutions, ensuring that the chosen technologies will provide optimal benefits in the long-term.
Green Power Purchase Agreements (PPAs)
Green PPAs offer an alternative for laboratories unable to install their own renewable energy systems. Through a PPA, a laboratory can agree to purchase electricity directly from a renewable energy provider, often at a fixed rate over a longterm period.
This arrangement supports the development of renewable energy projects while allowing laboratories to claim a reduction in their carbon footprint. PPAs can be particularly attractive in regions where the direct installation of renewable energy systems is impractical due to space, regulatory, or financial constraints.
Smart lab management systems
Smart laboratory management systems leverage the latest in Internet of Things (IoT) technologies, artificial intelligence and data analytics to optimise energy use. By integrating smart sensors, automated controls, and intelligent algorithms, laboratories can achieve a new level of energy efficiency.
For example, intelligent software that analyses data from sensors can identify patterns of energy use and areas for improvement. This software can make predictive adjustments to system settings, anticipate energy needs based on laboratory schedules, and provide recommendations for further energy-saving measures.
Training personnel
Sustainability and energy efficiency in the laboratory starts with the people who work there. Everyone that works in the lab should work collectively against energy waste. People should close fume hood sashes when not in use and turn off equipment when idle. Small actions like these alone can save significant amounts of energy and money in the long term.
Beyond formal training, creating a culture that values sustainability involves regular communication about goals, progress and opportunities for improvement. Recognition programs can celebrate individuals or teams that make significant contributions to making the laboratory as sustainable and effective as it can possibly be.
In conclusion, reducing energy waste in laboratories is a complex challenge that requires effort and initial financial investment, but the end results will be worthwhile. By implementing some of the switches and tactics described above, laboratories will not only become more sustainable but will see a lot of cost savings in the long run.
