Every year, Indonesia generates millions of tons of food waste, from production and distribution to consumption.
This is recorded in the *Report on Food Loss and Waste in Indonesia* (2021), a research collaboration between the Ministry of National Development Planning/Bappenas, Waste4Change, and the World Resources Institute.
The report categorizes food waste into two types: food loss and food waste.
Food loss refers to food wasted during production, post-harvest and storage, processing, and packaging.
Food waste refers to food wasted during distribution and marketing, and consumption leftovers.
Indonesia's food waste is largely comprised of food waste from the consumption stage, reaching up to 19 million tons per year.
Here is a breakdown of the estimated volume of Indonesian food waste during the 2000-2019 period, by category and supply chain stage:
Food loss:
* Production stage: 7–12.3 million tons/year
* Post-harvest and storage: 6.1–9.9 million tons/year
* Processing and packaging: 1.1–1.8 million tons/year
Food waste:
* Distribution and marketing: 3.2–7.6 million tons/year
* Consumption: 5–19 million tons/year
"It is estimated that 80% of food waste from the consumption stage originates from households, with the remaining 20% from the non-household sector," stated the Bappenas team in their report.
"44% of existing food waste consists of edible leftovers," they continued.
Besides being wasteful, food waste also generates greenhouse gas emissions, which have a detrimental impact on the environment.
"The total potential impact of global warming generated from FLW (food loss and waste) in Indonesia over the past 20 years is estimated at 1,702.9 Mton CO2-equivalent, or equivalent to 7.29% of the average greenhouse gas emissions in Indonesia over 20 years," said the Bappenas team.
In response, Bappenas has developed a strategy to reduce food waste at every stage of the supply chain, from training for food workers and infrastructure for efficient food production and distribution to consumer education.
"Responsible, integrated, and holistic FLW reduction and management can be part of efforts to accelerate the implementation of low-carbon development and green economic development, which can address the challenges of food security and nutritional deficiencies in Indonesia," said the Bappenas team.
