Zero waste restaurants This term has been gaining a lot of popularity in recent times. And rightly so, considering it highlights the importance of conservation of resources which is the need of the hour. Especially for restaurants, going ‘zero-waste’ is vital to improving their bottom line. 

According to FAO, approximately 1/3rd of all food produced in the world is lost or wasted every year. After agricultural production, restaurants are the next biggest source of global food waste generation. So clearly restaurants are a heavily wasteful business that can accelerate climate change.

Zero waste restaurants focus on reducing, reusing, and recycling their collective resources. Zero waste ideas and practices also encourage a circular economy, which is sustainable and improves profits. One study found that for every $1 that a restaurant invested in food-waste reduction strategies, it saved $7 on average.

Let’s look at the concept of zero waste restaurants in more detail.

What are the 5 R’s of zero waste?

With environmental waste piling up, and the deadly repercussions on our planet, eco-consciousness is more vital than ever. This is where the 5 R’s of zero waste guide restaurants on how to manage their waste sustainably. These R’s stand for:

Refuse, Reduce, Reuse, Recycle, Rot


Starting with the 1st R, this step involves refusing items with negative environmental impacts. It suggests carefully evaluating every purchase you make for your restaurant to eliminate items that you don’t need and don’t want piling in the garbage bins. 

For example, refuse to use all kinds of single-use disposable items like cutlery, straws, cups, bags, etc. Instead, switch to sustainable and green alternatives. Refuse to print hard copies of bills and instead offer to share it online with your customers. 

Saying NO may seem challenging considering a lot of these practices are widely common in most restaurants. But the ladder to zero waste starts with saying NO to everything that isn’t absolutely necessary.


Once you have aced the first step, the next thing is to reduce your current consumption of resources. Practice portion control and rotate your stock regularly to reduce the chances of ingredient and food wastage.

Remember a big part of becoming a zero waste restaurant involves understanding how much stock you need to order. Very often we overestimate consumption and want to leverage discounts on bulk buying that suppliers offer. This leads to over-stocking.

Order smartly to ensure you are not left with extra food supplies that will eventually get spoiled. Use a restaurant management software like EagleOwl to get insights into your daily/weekly/monthly consumption of ingredients to reduce the chances of over-stocking. 


Step 3 can be tricky for restaurants but is an important measure to get tangible results. This step dictates investing in reusable items. This could mean housing more products to ensure you reuse more and discard less.

For example, instead of serving plastic water bottles that immediately go to the trash bin, you use glass bottles to serve water to customers. Encourage guests to take their leftovers home when they can’t finish their meal.

You can switch to reusable containers when guests want to take leftover food. Another great idea is to request them to get their own containers from home to take leftover food. This helps create a responsible customer base and not just a responsible restaurant.


The fourth step is for all those things that cannot be refused, reduced, or even reused. This makes recycling a very important step of the zero waste process as it allows you to create something else. 

Find recycling plants in your area to get items like plastic, aluminum cans, glass containers, etc processed the right way. Failing to do so may lead to them ending up in landfills.


Lastly, you can opt for composting to rot your waste. Most restaurants just discard food waste in the garbage bins. Instead, they can be used to create organic fertilizer and reduce your restaurant waste footprint.

For example, vegetable peels, scraps, and food leftovers can be used to create compost that can be used to improve the quality of the soil. Many restaurants use this compost in their in-house and outdoor plant soil. 

It is crucial to understand what items can be composted and which can’t. For instance, meat, bones, and eggshells cannot be used in composting. If you don’t want to do composting in your restaurant, you can hand over your compostable items to a waste management company. 

Is zero waste possible in real life?

Is zero waste really ZERO? Or is there some waste percentage above which the restaurant is considered zero-waste? To qualify as zero-waste, a restaurant must divert 90% or more of its waste from going into the trash. This means, the restaurant has to ensure that there are no leftovers of any sort, be it the food or the food waste.

From an ecological point of view, going zero-waste is a necessity. We recommend it not just to minimize food wastage but also to reduce your restaurant’s environmental impact. But if you look at it from an economical point of view, it’s not cheap to implement waste prevention practices. 

In short, going zero-waste is theoretically possible but it sometimes comes with high expenses and a high sense of responsibility that people should develop.

For instance, let’s take the most common example of single-use plastic. To avoid using non-biodegradable single-use plastic straws, restaurants can turn to wooden or stainless steel ones. But then they cost more in comparison and have to be washed for reuse. Not every restaurant can afford the price hike and take the extra effort of washing these straws.

If reducing waste is not possible, the next option is to try to recycle it. Again, recycling doesn’t come cheap. Be it waste collection vehicles or building a recycling plant, everything requires significant investment. So getting rid of trash entirely may not be everyone’s choice even though the concept sounds very appealing. 

If you’re new to this concept, there are many ways to start reducing your restaurant’s waste. To help you out, we have shared below examples of restaurants already implementing these waste reduction practices. And the best part is, that these tips are easily manageable. Let’s take a look at these inspiring zero waste restaurants.
