生ごみ由来都市ガス、一般家庭に　全国初、１万世帯向け―鹿児島市

　鹿児島市は２７日、収集した生ごみを発酵させ、一般家庭に供給する都市ガスの原料「バイオガス」をつくり出す施設を含めた「新南部清掃工場」の完成式を開いた。市によると、生ごみからつくられたバイオガスを発電に利用する例はあるが、都市ガスにするのは全国初だという。同市では、約１３万世帯が都市ガスを利用しているが、施設の稼働により、周辺市などを含め約１万世帯分のエネルギーが生ごみ由来で賄われる見通し。（2021/12/27-15:38）

The southwestern Japan city of Kagoshima held a ceremony Monday to mark the completion of a new waste disposal plant, including a facility to produce biogas from untreated garbage for use as a source of city gas.
   There are cases in Japan in which biogas is used to generate electricity, and Kagoshima will be the first municipality in the country to use biogas to produce city gas, officials said.
   The facility, which will use untreated garbage collected in the city, is expected to generate biogas to provide about 10,000 households with city gas. In Kagoshima, some 130,000 households use city gas.
   "We want the facility to lead efforts to build a zero-waste and carbon neutral society and become a symbol toward reducing carbon dioxide emissions to net zero by 2050," Kagoshima Mayor Takao Shimozuru said at the ceremony.
   Takahito Fukuda, head of the new waste disposal plant, said, "We want citizens to feel that untreated garbage from households becomes city gas after going through many processes, leading to a shift to a carbon neutral society and local production and consumption of energy."
