这三个句子的结构基本相似，大体分析如下（仅供参考）：

1）

Kristianstad has gone further,是主句；

harnessing（不是hamessing）biogas for an across-the-board regional energy makeover是现在分词短语作伴随状语；

that has halved its fossil fuel use and reduced the city's carbon dioxide emissions by one-quarter in the last decade是定语从句（包含两个并列谓语has halved...and reduced...）修饰先行词makeover；

2）

It is made from biological waste是主句；

that in many cases would otherwise decompose in farm fields or landfills and yield no benefit at all是定语从句（包含两个并列谓语would decompose...and yield...）修饰先行词waste；

releasing heat-trapping methane into the atmosphere and contributing to global warming是两个并列的分词短语作伴随状语；

3）

Biogas plants can devour vast quantities of biological waste and manure是主句；

that would otherwise pollute the air and could affect water supplies是定语从句（包含两个并列谓语would otherwise pollute...and could affect...）修饰先行词waste and manure；

turning these materials into an energy source是伴随状语；
