How Restaurants and Food Businesses Can Go Green?


The food industry needs help with food waste. When food waste decomposes in landfills, it emits methane. It’s a powerful greenhouse gas that contributes to climate change. According to, methane is 34 times more potent than carbon dioxide. A study in the United States found that restaurants alone throw away about 11 million tons of food annually.

Single-use plastics, like cutlery, straws, cups, and packaging materials, add to the problem of plastic pollution worldwide. In the U.S., restaurants generate a significant amount of single-use plastic waste—with billions of plastic straws used annually.

Aside from that, more and more people are using takeout and delivery services, which has increased the amount of packaging waste. Using too many materials that can’t be recycled or composted contributes to the stress on landfills and the environment.

On the other hand, consuming significant energy and water can lead to greenhouse gas emissions and scarcity. The U.S. Environmental Protection Agency (EPA) says restaurants use more energy per square foot than other commercial buildings.

Meanwhile, using cleaning chemicals, pesticides, and other substances can lead to chemical waste that can hurt the environment and pollute waterways. One example is incorrectly throwing away cooking oils and fats, which can damage sewer systems and degrade water.

Food businesses and restaurants must take proactive steps to drive change toward a more environmentally responsible food industry. Here are some ways to help promote sustainability:

1. Energy Efficiency

Encouraging energy-efficient practices can significantly reduce carbon footprint. It includes using energy-efficient appliances, LED restaurant lighting, and programmable thermostats.

Here are some practical suggestions:

  • Using high-efficiency refrigerators, ovens, dishwashers, and ventilation systems with the Energy Star label can help consume less energy. Energy Star-certified commercial refrigerators use about 15% less energy than standard models.
  • LED lights are more energy-efficient, have a longer lifespan, and produce less heat. Using LED restaurant lighting can help lower energy consumption and electricity bills. They consume up to 75% less energy than traditional incandescent bulbs.
  • Restaurants can install programmable thermostats to regulate heating and cooling systems. A United States Department of Energy study shows that using a programmable thermostat can save up to 10% on yearly heating and cooling costs.
  • Smart kitchen practices such as batch cooking and investing in energy-efficient cooking equipment can decrease energy consumption and save time. Induction cooktops use up to 50% less energy than traditional gas or electric stoves.
  • Restaurants can cut their reliance on fossil fuels and contribute to a greener energy grid by using renewable energy sources. A restaurant with solar panels can use the sun’s power to make electricity, reducing carbon emissions.

Encouraging energy-efficient practices can minimize your environmental impact and lead to long-term cost savings.

2. Sustainable Sourcing

Locally grown and organic ingredients lessen the carbon footprint associated with long-distance transportation. It can also support local farmers, minimizing the use of harmful pesticides and synthetic fertilizers.

Choosing suppliers who use safe and healthy seafood practices can help protect marine ecosystems. Sustainable seafood means using responsible fishing methods that don’t deplete fish populations or harm the marine ecosystem. When a supplier is certified by groups like the Marine Stewardship Council (MSC), the seafood comes from well-managed fisheries.

On the other hand, fair trade and ethically sourced products, like coffee, tea, chocolate, and spices, are better for people and the environment. Fairtrade certification ensures companies provide reasonable wages and safe conditions for the workers while following environmental rules. Making sustainable choices can create a healthier future for the environment and local communities.


3. Waste Reduction and Recycling

Implementing effective waste management systems is crucial. You can develop waste management strategies to reduce carbon footprint and conserve resources.

You can follow these steps to minimize food waste:

  • Track Inventory Accurately: Inventory management software can help businesses make informed decisions and generate less waste.
  • Optimize Portion Sizes: Giving customers the option to change the size of their portions or customize their meals can help trim food waste and meet their preferences.
  • Donate Excess Food: Connect with local food banks or groups like the Food Recovery Network. They can make it easier to donate food and ensure it goes to people who can use it.

Meanwhile, recycling reduces the need for raw materials to produce new products. Setting up recycling stations for glass, plastic, paper, and metal can divert significant waste from landfills. Composting organic waste is another eco-friendly option that can benefit local gardens or farms.

4. Water Conservation

Water-efficient fixtures such as low-flow faucets, toilets, and dishwashers can minimize water usage. A restaurant replacing old faucets with low-flow ones can save water without affecting the dining experience.

Encouraging staff to adopt water-saving practices and training them to run dishwashers only when fully loaded can also make a difference. Inspecting plumbing systems and repairing leaks can help conserve water.

Harvesting rainwater for non-potable uses can further conserve water resources. A farm-to-table restaurant that uses rainwater for its herb and vegetable gardens shows a holistic approach by reducing reliance on outside water sources. Monitoring water usage and setting consumption targets can help identify improvement areas.

5. Packaging And Single-Use Plastics

Switching to reusable or compostable alternatives can reduce dependence on non-renewable resources. Food businesses and restaurants can shift consumer behavior towards more sustainable practices.

A restaurant that provides compostable takeaway containers made from plant-based materials supports resource conservation. A food truck that offers discounts to customers who bring their reusable containers encourages a culture of sustainability within the community. These examples can minimize the use of single-use plastics.

Opting for eco-friendly packaging materials promotes the circular economy. It’s where materials are reused, recycled, or returned to nature rather than discarded. A bakery that uses packaging made from recycled paper or biodegradable materials aligns with the circular economy.

Food businesses and restaurants that prioritize sustainability can attract a loyal customer base. They can differentiate themselves in the market by narrowing their environmental impact.


Adopting these eco-friendly practices can help food businesses and restaurants contribute to a more sustainable future. The food industry, consumers, and policymakers must work together to address environmental waste challenges.

Implementing eco-friendly practices such as reducing food waste, adopting eco-friendly packaging, and recycling can create a more eco-conscious food industry.
