Planning your meals and shopping smart can drastically cut down food waste. Stock take first, buy only what you need, and store perishables properly.

Food waste drastically affects the environmental, economic, and social dimensions of sustainability. Therefore, it is important to adopt different strategies not only to minimise or reduce the wastage of food but also to achieve the ‘Zero Food Waste’ goal. There are many ways to do this. Let us explore them.
As we have learnt before, a lot of food is wasted in households. The following pointers will help in reducing food waste.
• Plan your grocery and vegetable shopping. Buy what you need and buy to the extent you can eat. For this, conduct a stocktaking before you go shopping to know what is already there in your refrigerator or your kitchen cabinet. There is no point in buying vegetables and similar perishable items, for example, if you know beforehand that you won’t be able to use them for a week for some reason.
• Many people discard food prematurely because they misinterpret expiration dates. Familiarise yourself with date labels such as ‘‘sell by’, ‘use by’, and ‘best before’. Often, these dates indicate peak quality rather than safety. By understanding these labels, you can make more informed decisions about when to consume or discard food.
• Storing food properly can significantly extend its shelf life. For example, keeping fruits and vegetables in the refrigerator, using airtight containers, and storing leftovers in clear containers for better visibility can help prevent spoilage. Understanding the unique storage requirements of different foods is crucial in minimising waste.
• When preparing meals, portion sizes should be appropriate for the number of people that need to be served. Avoid over-preparing, as this can lead to leftovers that are eventually wasted.
• Be creative and transform the leftover vegetables into soups, stews, or other dishes. Leftover rice can be used to make fried rice or other dishes. Leftover chapatis can be used to make fried chapatis.
• Convert all your waste food into nutrient-rich soil by subjecting it to composting.
• Donate the surplus food to appropriate organisations that operate ‘food banks’. Several NGOs in India focus on collecting and donating food. Some prominent ones include the Akshaya Patra Foundation, Feeding India, and Rise Against Hunger India. These organisations, along with others like Annamrita Foundation and Robin Hood Army, play a crucial role in addressing hunger and malnutrition in the country. These and a few other organisations focus on redistributing excess food not only from homes but also from various events like weddings, hotels, and restaurants to those who are hungry.
Restaurants and food service establishments must create a culture of continuous improvement by regularly evaluating and adapting their waste management practices. Innovative food waste management practices are essential for restaurants and restaurateurs to reduce their environmental impact, support local communities, and increase profits. By implementing a comprehensive strategy, from source reduction to customer engagement, companies can choose how they deal with food waste and contribute to a more sustainable future.
Dear readers, I have tried to present this very important topic of food waste to you through a few articles. The strategies for reducing and minimising food waste discussed in this article are just a few representative guidelines. You can keep on making value additions to these and come up with more innovative solutions to this problem. Please stop wasting food and let your children follow in your footsteps to prevent wasting food in your homes. It is their right to live in an environment that is healthy and sustainable.
