GREEN MACHINE

An introduction to the innovative (and smelly) processes that turn municipal food waste into electrical energy.

Donnelly follows the journey of food scraps from kitchen through composting bin and collection truck to a municipal digester, where the waste undergoes both human-engineered and microbe-assisted transformations. The author subjects her text to syllabic verse in rhymed triplets, a choice that places meter above clarity. Describing the digester, she writes: “A place where the waste / isn’t wasted: a tank / with the power to power our town, / where trash becomes gas, / and good riddance—that stank! / That’s the power of food breaking down.” Jacques’ illustrations adopt a retro, mid-20th-century look. Cutaways reveal the simplified inner works of the digester tank and electrical generator. Diverse workers are depicted in rather static poses; the featured family members have dark hair, varied brown skin tones, and minimally rendered, dot-and-comma facial features. “Tiny” microbes appear as large, colorful critters with googly eyes and smiles; there’s no indication that in reality they’re invisible to human eyes. A double-page summary (“Follow the Food Energy!”) reuses illustrations from previous pages to illustrate the food-to-electricity process. Within two concluding pages of facts, fossil fuels are characterized as “nonrenewable,” without mention of their dominant role in the climate crisis.

Constrained verse distracts from timely, basic information about transforming food into fuel.
