Today, we will share 10 practical zero waste cooking tips that will lower your impact on the environment and have a more eco-friendly kitchen.

As you are aware, cooking can be messy and it can be worse if we don’t realize the harm irresponsible food preparation can do to our planet.

For starters, we cook and eat food at least twice a day, which means we generate a lot of waste.

There’s also the issue of proper food handling and using of unsustainable ingredients in our meals.

With a good knowledge on zero waste cooking, you can effectively reduce food waste and even save money!

But first…

What is zero waste cooking?

Zero waste concept applied in cooking means that we are trying to achieve literal no-waste in pre and post-production of our food.

Realistically, there will always be a trace of waste in our food because most of our supplies use plastic packaging.

Though many companies have shifted to paper bags, cups, plates, and other eco-friendly cooking utensils and sustainable food containers, more people are still practicing the use of plastic.

So without further ado, below are 10 tips on zero waste cooking, from picking up ingredients to proper handling of spoiled food.

1. Plan your meals weekly

Most households buy supplies that last for a week or more.

But most of the time, they don’t plan their meals and buy whatever they see without thinking.

Planning meals will organize our weekly menu, gives us enough time to shop for sustainable ingredients, pick up supplies more efficiently (reducing trips on market), and will help avoid too many food leftovers.


In zero waste terms, meal planning should be under the following criteria:

  • Every part of the fruits and vegetables you buy should be consumable as possible
  • The number of products you buy should coincide with their maximum shelf life
  • Buy only what you need for the week
  • Avoid as much plastic packaging as possible
  • Buy from the fresh produce section or bulks section

2. Shop cooking ingredients locally

If we are talking about fresh produce, buying from a local source is the best.

Locally sourced produce is numerous in suburban areas with broad lands suitable for farming. 

Local produce and ingredients have less carbon footprint compared to imported ones.

They are more fresh too and are likely to be not treated with preservatives.

3. Consider starting a mini-farm


Having a home garden has many benefits, especially in zero waste cooking.

A mini-farm of essential cooking herbs and spices will reduce your need to go to groceries and be handed products in plastic packaging.

It will also help you save money!

Moreover, compostable kitchen waste will have an automatic use if you have your mini garden.

You can compost organic kitchen waste and effectively help reduce the trash you send to landfills while gaining access to natural and organic fertilizer at the same time.

Having a mini garden will make your household more sustainable.

4. Use reusable bags when shopping

Shopping without your own bag won’t reassure you that the seller will use eco-friendly packaging for your products.

Frequently, they will use plastic packaging, another waste you don’t have to manage if you bring your own bag.

We should use reusable bags for many reasons. Aside from being eco-friendly and avoiding pollution, you can personalize it according to your taste. 

It provides a certain level of comfort compared to paper and plastic bags. It is also more durable and long-lasting.

Eliminating plastic has come a long way, and we should take part in simple ways. Using reusable bags is one of them.

5. Use zero waste cooking utensils


Be mindful of the kitchen products you buy.

They generate most of the waste at home, like condiments, cooking utensils, and food containers.

There are various eco-friendly kitchen product alternatives available to maximize your sustainable options.

Here are a few examples of eco-friendly kitchen products that you must have to reduce your impact on the environment:

Eco-friendly cookware

Eco-friendly cookware must have the following criteria:
