Taiwan would face an estimated daily shortfall of 500 tonnes in kitchen waste capacity if the government were to continue banning its use as pig feed following last month’s outbreak of African swine fever, Minister of Environment Peng Chi-ming (彭啟明) said today.
The Ministry of Environment is working with local governments to review capacity and negotiate land use, while investigating medium to long-term solutions, he told reporters ahead of a meeting at the legislature.
The ministry is exploring biomass energy solutions, rapid composting and black soldier fly farming, in which larvae are raised to convert organic waste into animal feed and fertilizer, he said.

Assessments are expected to take one to two years, he added.
Epidemiological results released on Monday showed that the first case of African swine fever detected in Taiwan was likely caused by improperly sanitized kitchen waste used as pig feed at the infected hog farm in Taichung.
Use of kitchen waste as pig feed was banned temporarily after the outbreak last month, and extended after Monday’s finding.
Last year, Taiwan produced 772,000 tonnes of kitchen waste, or 2,115 tonnes per day, which included 505,000 tonnes from households and 267,000 tonnes from businesses, ministry data showed.
The estimated shortfall of 500 tonnes would mostly come from restaurants, catering companies and other businesses, which poses a greater challenge than household kitchen waste, as it cannot be integrated into existing systems, Peng said.
The issue would vary by region, with the six special municipalities facing the greatest pressure and requiring tailored solutions, he said.
This is particularly true in Taichung, which already struggles with waste disposal, he said.
As for Pingtung County, it can handle the 40 tonnes of kitchen waste it produces per day, but many counties in the south send their waste to Pingtung for treatment and could soon face difficulties with the increased volume, he added.
Kenting National Park service technician Yang Jien-fon (楊政峰) won a silver award in World Grand Prix Photography Awards Spring Season for his photograph of two male rat snakes intertwined in combat. Yang’s colleagues at Kenting National Park said he is a master of nature photography who has been held back by his job in civil service. The awards accept entries in all four seasons across six categories: architectural and urban photography, black-and-white and fine art photography, commercial and fashion photography, documentary and people photography, nature and experimental photography, and mobile photography. Awards are ranked according to scores and divided into platinum, gold and
More than half of the bamboo vipers captured in Tainan in the past few years were found in the city’s Sinhua District (新化), while other districts had smaller catches or none at all. Every year, Tainan captures about 6,000 snakes which have made their way into people’s homes. Of the six major venomous snakes in Taiwan, the cobra, the many-banded krait, the brown-spotted pit viper and the bamboo viper are the most frequently captured. The high concentration of bamboo vipers captured in Sinhua District is puzzling. Tainan Agriculture Bureau Forestry and Nature Conservation Division head Chu Chien-ming (朱健明) earlier this week said that the
The Chinese Nationalist Party (KMT) caucus yesterday said it opposes the introduction of migrant workers from India until a mechanism is in place to prevent workers from absconding. Minister of Labor Hung Sun-han (洪申翰) on Thursday told the Legislative Yuan that the first group of migrant workers from India could be introduced as early as this year, as part of a government program. The caucus’ opposition to the policy is based on the assessment that “the risk is too high,” KMT caucus secretary-general Lin Pei-hsiang (林沛祥) said. Taiwan has a serious and long-standing problem of migrant workers absconding from their contracts, indicating that
