Nestlé—a major nutrition, health and wellness company— seeks to enhance the quality of life and contribute to a healthier future. Our ambition for the planet is to steward resources for future generations, which guides our work toward achieving our 2020 commitments and supporting the United Nations Sustainable Development Goals.
WHY IS NESTLÉ MEASURING FOOD LOSS AND WASTE?
Nestlé is committed to further playing its part in helping to reduce food loss and waste. This helps the company secure supplies of agricultural raw materials it requires, as well as having a positive impact on society by supporting rural development, water conservation, and food security. This is in line with Nestlé’s “Creating Shared Value” approach to doing business.
We are continuously making efforts to improve the environmental performance of our operations in order to preserve natural resources and to be successful in the long term. Since 2006, Nestlé has reduced total waste for disposal* from its factories by 77 percent. With 182 Nestlé factories achieving zero waste for disposal at the end of 2016, we are now working toward zero waste for disposal in our sites by 2020. We measure food loss and waste to track progress against our targets.
* Waste for disposal: Any material that leaves a site and is destined for final disposal with no economic or ecological value. It includes landfilling and incineration without energy recovery.
WHAT HAS BEEN YOUR EXPERIENCE WITH USING THE FLW STANDARD?
In 2014, to further understand and reduce the waste occurring in our value chain, we initiated a milk loss and waste mapping exercise in Pakistan, applying the draft Food Loss and Waste Accounting and Reporting Standard. Reporting our data in conformance with the FLW Standard has been a valuable process that allowed us to identify quantities and destinations for each type of milk loss and waste along the value chain.
The Pakistani dairy sector was chosen because of its complexity, the high volumes involved, and because it provided an opportunity to test the efficiency of our dairy hub model. Working with external consultants, we mapped the value chain from farms to consumers. In total, Nestlé processes 480 kilotonnes of milk a year, sourced mainly from traditional small farms but also some larger operations. Before reaching our factories, the milk transits through village milk collection and chilling centers. After processing, 90 percent of it is sold through traditional trade channels to consumers.
For each stage of the value chain, we analyzed all potential causes of loss and waste. Losses and waste were quantified (either through direct observation or interviews with farmers, retailers, consumers, and others) and extrapolated across the value chain.
WHAT CHALLENGES IN MEASURING FOOD LOSS AND WASTE HAVE YOU ENCOUNTERED AND HOW DID YOU OVERCOME THEM?
To overcome the challenge of measuring food loss and waste in a complex value chain in Pakistan, we conducted a detailed mapping across the entire value chain (from farms to consumers). This allowed us to define more precisely the scope and to identify the main food loss and waste sources and destinations.
To overcome the challenge of measuring milk loss and waste in the farming stage, we conducted a sampling exercise during field visits and linked the observations with the interviews of people working in the field, professionals (vets), and dairy experts. The estimates were then extrapolated to a larger sample (of same farm size and practices) and then to the whole country.
WHAT ACTION HAS NESTLÉ TAKEN AS A RESULT OF MEASURING ITS FOOD LOSS AND WASTE?
The total milk loss and waste across all stages of the value chain was estimated to be only 1.4 percent of milk produced. About 40 percent of the losses and waste were generated at the farm level stage. This is significantly lower than an estimate reported in an Asian Development Bank study in 2004. That study found that approximately 15 to 19 percent of milk sold by Pakistani farmers was lost or wasted en route to market.
This low level of loss and waste confirmed for us that the steps we have been taking over many years to reduce loss and waste are working. Actions we have taken include:
- Providing adequate cooling, storage, and transportation systems that are used by farmers
- Training farmers and sharing best practices among them on approaches that not only help increase milk production, but also reduce post-harvest losses (e.g., rejection by chilling centers)
- Implementing lean management and problem solving methodologies to identify, reduce, and report losses and waste from farm to factory.
Losses could be reduced even further through improved management of products at the retail stage. For more information on our actions related to food loss and waste, please see our “Nestlé in Society” report at www.nestle.com.
WHAT IS INCLUDED IN THE SCOPE OF THIS FLW INVENTORY?
The following figure visually represents the scope of Nestlé Pakistan’s milk loss and waste inventory using the FLW Standard. While all possible types of destinations were assessed in the inventory, only landfill, refuse/discards/litter, and sewer/wastewater treatment were considered as milk loss and waste.
*Dairy products (GSFA 1.1.1.) or (CPC2.1 Group 22110)
**Five stages (ISIC codes): 0141 – Raising of cattle and buffaloes; 1050 – Manufacture of dairy products; 4912 – Freight rail transport; 4721 – Retail sale of food in specialized stores, and 9820 – Undifferentiated service-producing activities of private households for own use.
HOW DOES THIS INVENTORY MEET THE FLW STANDARD’S REQUIREMENTS?
The table below provides a summary of how this FLW inventory meets the eight reporting and accounting requirements contained in the FLW Standard.
|FLW STANDARD REQUIREMENTS & DESCRIPTION OF NESTLÉ’S FLW INVENTORY|
|1. Base FLW accounting and reporting on the principles of relevance, completeness, consistency, transparency, and accuracy
|2. Account for and report the physical amount of FLW expressed as weight
Reported as tonnes
|3. Define and report on the scope of the FLW inventory (see FLW Standard for additional details)
Timeframe: Data reported for January 1 – December 31, 2014 (data collected from May-Dec 2014)
Material type: Food (No inedible parts were included because this study focused on dairy products that do not have inedible parts, e.g., liquid milk, powder milk, and yoghurt)
Destinations: Landfill, refuse/discards, sewer
Related issues: Weight of packaging is excluded. No calculation was needed to separate packaging weight from food loss and waste.
In the factories, residual FLW is flushed through pipes during the cleaning process. The effluent is sent through an on-site wastewater
treatment process. The weight of the remaining sludge is included in this inventory.
|4. Describe the quantification method(s) used. If existing studies or data are used, identify the source and scope
Direct weighing and surveys (interviews and visits); additional details are provided below under “About the methodology.”
|5. If sampling and scaling of data are undertaken, describe the approach and calculation used, as well as the period of time over which
sample data are collected (including starting and ending dates)
See details below under “About the methodology.”
|6. Provide a qualitative description and/or quantitative assessment of the uncertainty around FLW inventory results
The degree of uncertainty varies depending on the source of the information and on the stages in the chain. A qualitative estimate is provided
for each stage based on a general scale of 1–10 (with 10 signifying very accurate data). Specific qualitative scores for each stage were used
to calculate a weighted uncertainty of “8.” See additional details under “About the methodology.”
|7. If assurance of the FLW inventory is undertaken (which may include peer review, verification, validation, quality assurance, quality
control, and audit), create an assurance statement
|8. If tracking the amount of FLW and/or setting an FLW reduction target, select a base year, identify the scope of the target, and
recalculate the base year FLW inventory when necessary
