Frequently Asked Questions

What is compost?

Compost is the sustainable, recycled, nutrient rich soil amendment product of decomposed organic waste.

What is composting?

Composting is the process by which organic material - yard scraps, food scraps, etc. - is made into soil, rather than thrown in the trash and eventually sent to a landfill. By doing so, we are able to create more nutrient-rich soil and reduce our reliance on landfills, which are quickly filling up and emitting greenhouse gases that contribute to global warming.

Why should I compost?

● You like saving money. By composting food scraps and other compostable material,you greatly reduce the amount of material going into your trash dumpster. This means a reduction in frequency of trash pickups, saving you money.

● You care about Milwaukee’s future. Every year, Milwaukee produces enough organic material to fill multiple Miller Park. Diverting compostable material places less pressure on our landfills, which are slowly running out of space. By contrast, composting takes nutrient-rich material, accelerates its breakdown, returns it to nature, helping to grow trees, gardens, and crops.

● You want to reduce your carbon footprint. Compost provides carbon sequestration.In other words, composting will help capture carbon dioxide, helping you reduce your carbon footprint. If you want to learn more, please visit the link to EPA website here.

What happens to my compost materials?

We help turn ALL of our organic material back into soil at Blue Ribbon, a local farm in Caledonia, WI, where it is processed for 4 - 6 months. After the process is complete, it is screened and sold by Compost Crusader as finished compost.

This sounds great! Can Compost Crusader pick up compostable material from my house?

If you are within the Curbside Collections Program in Milwaukee and Shorewood, you may be eligible to enroll through the City’s collection program. Check the eligibility map to see if you qualify.

If your residence is not in the pilot program, you can still compost your leftover food through Kompost Kid.

What about my place of business?

We currently service the larger Milwaukee area. Please give us a call to create a plan of action to help start composting.

Are other businesses really composting?

Yes! Our customer list is comprised of local restaurants, florists, breweries, schools, mid-sized businesses and large corporations. Everyone can compost! For additional details, please see our shortlist of highlighted customers here.

Can I purchase compostable bags from you?

Yes!. We sell certified compostable bags that range in capacity from 8 gallons to 64 gallons, depending on the size of your compost receptacle. We will deliver bags when we pick up compost from your home or place of business. Click here to order.

What if I buy compostable bags from Amazon?

That’s fine, so long as the bags themselves are clearly labeled as BPI certified compostable. If they don’t display that information on the bag itself, we will ask you to provide verification that the bag is certified compostable; this is to ensure compost materials are not contaminated by non-compostable materials.

Can I purchase compost from you?

Yes! Once our partner farm has finished composting the materials, we sell a portion of it out of our office in St. Francis, WI. Please bear in mind that we generally have a limited amount of compost we can sell at a time; please call ahead to ensure we have finished compost in stock for you to purchase, and to schedule a pick-up time. Please note that at this time we do not deliver finished compost.
