Food Waste Treatment FAQ

The price depends on daily capacity. First confirm a number: roughly how many tonnes of food waste do you process per day? Local population also works (10,000 people ≈ 1 t/d). Once the tonnage is confirmed, I will immediately give you the matching equipment list and quotation.

Because the "owner-supplied scope" differs between the two — the price only covers what we supply. The 100 t/d pretreatment & carbon-source scheme has 36 line items, of which 17 (high-temp grit tank, steam generator, PLC control, deodorization, instruments, piping & valves, etc.) are owner-supplied and excluded from the price, so the total looks low; the 50 t/d sorting & oil-recovery scheme has all 42 items supplied and priced by us, so the total is naturally higher. The price only reflects our supply scope, not the total project investment. To compare total investment, include the owner-supplied items, or ask us for a complete configuration list that includes them.

As a rule of thumb, 10,000 people produce 1 t/d. For example, 300,000 people ≈ 30 t/d. Actual collectable volume depends on local collection coverage and the number of catering outlets; we will verify with the urban-management bureau collection records before fixing the final scale.

Yes. For 1–3 t/d we can build a simple integrated solid-liquid separation unit at 92,000 CNY total, suited to bin collection and county-level start-up projects. For 5–10 t/d, the sorting & oil-recovery configuration is 445,000 CNY.

The equipment is similar but the processes differ and must be distinguished. Food waste (restaurant/canteen leftovers) is high in water and oil, with the focus on sorting and oil recovery; kitchen waste (residual waste from residential sorting) has more impurities and lower moisture, requiring different front-end sorting and dewatering. Tell us the feedstock source clearly and we will configure the matching process.

There are several routes: make organic fertilizer, breed black soldier fly (BSF) for insect feed, run anaerobic digestion for larger tonnages, or send it with the inorganic residue for landfill, incineration or sale. Which do you prefer? We work backwards from the output to size the equipment and workshop.

Inorganics (plastic bags, cutlery, glass, metal) are collected separately after sorting and dewatering, then sent for offsite disposal, incineration or landfill. This is clearly defined as a supply boundary in the scheme.

Yes. You can sell the oil yourself, or we can help collect it; the government does not regulate it. Based on 230,000 people, about 1.84 t of oil per day; at 6,000 CNY/t that is 11,040 CNY/day, which usually covers a large part of operating cost.

There are several discharge routes: (1) treat on site to discharge standard; (2) hand to the incinerator or landfill, which have leachate treatment; (3) hand to the municipal WWTP; (4) sell as carbon source to a WWTP. If there is no local WWTP, we will design the wastewater treatment unit separately and include it in the supply scope.

Odor passes through deodorization equipment and is discharged to standard. The deodorization system (biofilter / scrubber etc.) can be standard or listed separately in the quotation, depending on your requirements.

Yes. The BSF route uses the sorted organic solid slurry for breeding, or blends it with straw powder into insect feed. The scheme configures pretreatment and breeding rooms separately. Tell us how much fresh/dried insect you plan to produce and we will design by tonnage.

Based on industry experience, treatment cost is about 160–200 CNY/t. This depends heavily on tonnage, labor, power and heat source; we will break it down for you in the formal proposal.

Tell us your budget range (in 10k CNY). We have ready configurations from the 92,000 CNY compact unit up to medium/large lines at 445k, 1.12M, 3.699M and 4.675M CNY, so we can select within your budget band.

Payback depends on three things: the government waste-treatment fee (CNY/t), grease sales revenue, and compost/insect-feed sales. Tell us the local treatment fee and oil purchase price and we can work out the numbers together.

First, we recommend securing the exclusive concession — i.e. confirming whether the government concession (e.g. the food-waste resource-recovery license issued by the urban bureau) is already in hand. With the concession, collection channels and subsidies are much easier to secure.

We recommend confirming the operating model first: self-operated, contracted, or other. Installing equipment before the license is settled makes collection volume hard to guarantee. We can issue the scheme and investment estimate first and help you prepare the project approval and concession materials.

Yes. 120–240 L bin collection corresponds to ~0.1–5 t/d integrated units. The key for bin collection is the feed method (lift specification) and truck tonnage; once those are confirmed, the pulper selection is fixed.

The price includes installation and commissioning guidance; installation is listed line-by-line in the equipment list to avoid double counting. On site we need: control cabinet location and total power, heat source (steam / biomass boiler), piping & valves, instruments, platforms, ladders and guardrails — the list marks who supplies each.

Terms differ by scheme: the 1–3 t scheme at 92,000 CNY excludes tax and freight; the 50 t scheme at 3,699,000 CNY includes tax, excludes freight, and includes installation, commissioning and 3 days of training. The tax and freight terms are written out clearly on the formal quotation.
