How to Set Up a Composting Program at a Hotel
Hotels generate substantial organic waste streams: kitchen prep waste from restaurants and banquets, plate waste from dining service, food spoilage, breakfast buffet leftovers, in-room food service, lobby coffee operations. A typical mid-sized full-service hotel might generate 200-1500 pounds of organic waste daily. Composting programs can divert most of this from landfill while supporting sustainability commitments,…

A Compostable Hummingbird Feeder
The phrase ‘compostable hummingbird feeder’ raises an interesting question. Conventional hummingbird feeders are durable glass or plastic, designed for years of outdoor use, holding sugar-water nectar that needs frequent refilling and cleaning. The sustainability story of a typical feeder is about long lifespan, not single-use compost. So what would a compostable hummingbird feeder actually be?…

Are Compostable Cups Strong Enough for Hot Coffee?
Yes, compostable hot cups handle hot coffee. The question gets asked because PLA — the most common compostable cup coating — has lower heat tolerance than petroleum plastic alternatives. PLA softens around 140°F; coffee comes out of the brewer at 195-205°F and is typically served at 160-180°F. The question seems to suggest a problem. In…

Sour Milk: Cooking Uses, Pet Treats, and Last-Resort Compost
Sour milk doesn’t have to go down the drain. Slightly soured milk — past its prime but not yet spoiled — has substantial culinary value. Pancakes, biscuits, cornbread, marinades, soups, even basic homemade cheese all use sour milk as their working ingredient. Pets often enjoy small amounts. And as last resort, modest amounts can integrate…

Can I Compost Yard Waste in a Kitchen Bin?
The short answer is: technically yes, but practically no for most yard waste. Kitchen bins are designed for kitchen scraps — small volumes of food waste collected daily on a countertop or under a sink. Yard waste is usually too bulky and too voluminous for a typical kitchen bin to handle effectively. Small amounts of…

Earth Day Tree Plantings: Connecting to Composting
Earth Day tree plantings — annual events where communities, schools, and organizations plant trees on April 22 — celebrate environmental commitment with concrete action. Compost makes those trees work better. Trees planted into compost-amended soil establish faster and grow stronger. Compost mulched around new trees retains moisture and suppresses weeds. Trees produce substantial leaf litter…

How to Compost When You Have Multiple Pets
Households with multiple pets generate substantial organic waste streams: pet hair, food spillage, bedding from cages and litter boxes, kitchen scraps from meal preparation. Some of it composts cleanly; some requires careful handling; some is best kept separate from food-garden compost. The pet-loving household working through composting needs different protocols for different pet types —…

Fresh Herb Stems: Composting With Maximum Flavor Extraction
Most home cooks treat fresh herb stems as compost-bound waste. The leaves go to the dish; the stems go to the bin. The pattern misses substantial flavor and food value. Parsley stems are nearly as flavorful as the leaves. Cilantro stems carry the herb’s aromatic core. Even woody thyme and rosemary stems release flavor when…

What’s the Best Worm for a Worm Bin?
The short answer: red wigglers (Eisenia fetida). They’re the gold standard for vermicomposting and the species most commercial worm farms sell for home bins. Red wigglers tolerate the compact, warm, food-rich conditions of a bin. They reproduce quickly. They process food waste at substantial rates. They don’t burrow deep like garden earthworms (which would die…
