Independent testers say eighty-six percent of what goes in comes out as fuel.
这是个宾语从句,eighty-six percent of what goes in comes out as fuel 做 say 的宾语.
而这个宾语从句里面,eighty-six percent of what goes in 做 comes out 的主语,eighty-six percent of what goes in 可以看作是名词性的主语从句,其中what 就是代词,并不是引导句子的关系词,指代的是“输入的东西”,根据楼主上下文,应该指代的是塑料.
整个句子就是这样的一个结构.

英语翻译
1、The UK market for organic food grew by 55 percent in 2000,while the food market as a whole grew by only one percent.Yet only seven percent of British shoppers account for nearly 60 percent of organic sales.However popular the idea of organic farming may be,it is still an interest for only a few people.
2、So what makes the idea of organic farming popular?Organic farming means farming with natural materials,rather than with man-made fertilizers or pesticides.Organic farmers rely on many methods----- such as crop rotation and the use of resistant varieties,because they are necessary for organic farmers ot compensate for the shortage of man-made chemicals.

赞同二楼的翻译,分析:整个句子为特殊疑问句,what percent of the increase in the total numbers of magazine为疑问词,关键词是“what percent”,“of”译为“的”就行,译为“在杂志所有的读者增加的数量中有多少比重”,was自然是谓语,后接表语“the increase in the number of readers in the 31-40 age group”,译为“31-40年龄阶层读者的增长数量”,所以整个句子即为“增加的读者中,31-40年龄阶层增长的比重占多少.”(希望帮到你!)
