In the age of e-commerce and rapid product delivery, warehouses are the backbone of our modern supply chain. However, their efficiency often comes at an environmental cost. This article explores practical steps you can take to reduce your warehouse's environmental footprint. By implementing these strategies, you'll not only be contributing to a healthier planet but potentially saving money on energy and waste disposal costs.

What is Earth Day and how does it relate to sustainable warehousing?

Earth Day is celebrated on 22nd April every year, engaging more than 1 billion people. The annual event raises awareness about environmental issues and promotes sustainability, highlighting the critical need to protect planet Earth. Since 1980, it's been a day to reflect on the impact our actions have on the planet and take steps towards a healthier future.

The World Economic Forum (WEF) highlights that the industrial real estate sector, which includes warehouses, is responsible for more than 20% of global greenhouse gas emissions*. This substantial contribution is primarily due to the high energy consumption required for heating, cooling, and lighting large warehouse spaces. Beyond energy use, the WEF emphasises the industrial real estate sector's impact on resource consumption. Warehouses utilise a significant amount of raw materials for construction and ongoing operations, and the packaging waste generated within the warehouse when it's operating can be substantial.

Did you know, for third-party logistics (3PL) providers and those operating warehouses, utility bills account for at least 10% of company revenue? You can reduce this by implementing environmental friendly solutions that align with Earth Day's values, here's how:

> Reduced environmental footprint: Warehouses can be significant energy consumers and waste generators. Sustainable practices in warehousing minimise energy use, waste generation, and pollution, contributing to a healthier planet.

> Resource conservation: Earth Day emphasises the importance of resource conservation. Sustainable warehouses promote responsible use of resources like energy and materials.

> Long-term sustainability: Sustainable practices in warehousing ensure responsible use of resources for the long-term, promoting a sustainable future for generations to come.

What does this mean for warehouses?

Sustainable warehouse development reduces the impact on the environment through the use of alternative materials, life cycle of the construction, design, operation and demolition of these industrial facilities.

Building a sustainable foundation

Sustainability starts at the ground level, even before a product enters the warehouse. Here's how to make your physical space more eco-friendly:

> Location, location, location: Consider the warehouse's proximity to transportation hubs and customer base. A strategically located warehouse reduces transportation distances and associated emissions.

> Building green: When possible, use recycled or sustainable building materials during construction or renovation. Additionally, invest in energy-efficient features like skylights for natural light and cool roofing to minimise heat absorption.

Harnessing power efficiently

Warehouses are notorious for high energy consumption. Here's how to cut down on your electricity usage:

> LED lighting revolution: Replace traditional incandescent or fluorescent lights with LED alternatives. LEDs are significantly more energy-efficient and last longer, reducing long-term costs.

> Smart lighting control: Install motion sensor lighting systems to ensure lights are only on when necessary. This simple switch can significantly reduce energy waste, especially in areas with low daytime traffic.

> HVAC optimisation: Regularly maintain your HVAC system to ensure peak efficiency. Additionally, explore programmable thermostats to regulate temperature fluctuations when the warehouse is unoccupied.

Optimising warehouse operations

Small operational changes can have a big impact on your environmental footprint. Here are some ways to streamline your warehouse processes:

> Space utilisation: Optimise your storage layout to maximise vertical space and minimise empty aisles. This reduces overall energy consumption needed to maintain a comfortable temperature throughout the warehouse.

> Picking and packing efficiency: Implement a streamlined picking and packing system to reduce travel time for workers and forklift trucks. This minimises fuel consumption and wear and tear on machinery.

> Automation for efficiency: Consider warehouse automation solutions like automated storage and retrieval systems (ASRS) for specific tasks. While there's an initial investment, automation can significantly improve picking and packing efficiency, reducing overall energy consumption.

> Electric forklifts (MHE): Eliminating the need to fossil fuels is not only good for the environment but it is also safer for employees. They produce significantly less noise and pollution, helping to reduce your environmental impact and improving warehouse conditions.

Waste reduction and responsible disposal

Warehouses generate a substantial amount of waste from packaging materials and damaged goods. Here's how to minimise waste and dispose of it responsibly:

> Sustainable packaging: Partner with suppliers who use eco-friendly packaging materials that can be recycled or composted. Additionally, explore ways to minimise packaging altogether, like using reusable containers for specific products.

> Waste management: Implement a comprehensive waste segregation program. This allows for efficient recycling of paper, cardboard, plastic, and other materials. Partner with a reputable waste management company that prioritises responsible disposal practices.

> Inventory management: Maintain accurate inventory control systems to minimise overstocking and the potential for product damage that ends up as waste.

The power of people

Sustainability isn't just about technology and infrastructure; it's also about your team. Here's how to create a culture of sustainability within your warehouse:

> Employee education: Train your employees on the importance of sustainable practices and how their actions can contribute. This could include proper waste segregation, responsible energy usage (like turning off lights during breaks), and a focus on minimising damage during handling.

> Incentivise Green choices: Consider implementing incentive programs to encourage employee participation in sustainable practices. Recognition and rewards can further motivate employees to make eco-friendly choices.

> Open communication: Maintain open communication channels with your employees. Encourage them to suggest ideas on how to improve warehouse sustainability.

Examples of sustainable warehouses

Here’s some examples of sustainable, best-in-class warehousing.

Global example:

NewLogic III building, nicknamed ‘The Tube’

The NewLogic III building, nicknamed ‘The Tube’, is a 60,500m² facility with warehouse and office space that is airtight with extra insulation. A photovoltaic system (solar) on the roof consisting of 11,620 panels generates more electricity than the building consumes, with excess power going into the grid, meaning it is both energy and CO2 neutral.

The warehouse has natural light flooding through large triple-glazed windows, reducing the amount of electricity needed for lighting and makes it a more pleasant space to work in.

The building also features a heat pump, automatically dimming LED lighting, charging points for electric vehicles and technology that monitors water consumption and CO2 concentrations.

National example

3PL provider, Toll Group, was responsible for building the first-ever facility in Australia that achieved a whole-of-building carbon neutral certification under the National Carbon Offset Standard (NCOS) for buildings.

In partnership with Nike, Toll's custom-built warehouse (owned by Stockland) in Altona North, Victoria, leverages new technologies to help reduce energy and greenhouse gas emissions. This included upgrades to a 2.5-kilometre-long conveyor system powered by 145 individual electric motors, and the retrofitting of 1,300 light fixtures with high efficiency LEDs.

Every step towards environmental sustainability counts

Creating a sustainable warehouse is an ongoing process. By implementing these strategies and fostering a culture of environmental awareness, you can make a significant difference. Remember, by adopting sustainable practices, warehouses can not only help the environment but also potentially see cost savings through reduced energy consumption and waste disposal fees. Earth Day serves as a timely reminder for businesses to consider their environmental impact and take action towards a more sustainable future.
