By-product pricing is setting prices for the secondary outputs of a production process, such as sawdust from timber, whey from cheese-making or ash from power plants. It is a product-mix pricing strategy: income from the by-product lowers the effective cost of the main product, so a firm can price that product more competitively. The by-product’s price only needs to cover the cost of handling and selling it.
How it works
Where you see it today
For AI products, conversations can be a by-product with value of their own. Google’s Gemini Apps privacy notice says conversation data is used to provide, improve and develop its products and machine-learning technologies, with settings that limit some of that use. Free or cheap tiers make more sense when usage itself improves the next model.
Economists have argued that treating user data as capital collected for free neglects the people who create it, and proposed treating it partly as labour (Arrieta-Ibarra et al., 2018). The debate is about who captures the value of a by-product.
In 2022 Microsoft and the energy company Fortum announced that waste heat from planned Microsoft data centres near Helsinki would be converted into district heating for homes and businesses. As AI drives data-centre growth, heat is becoming a by-product with a market.
The US Environmental Protection Agency describes the two largest encapsulated uses of coal combustion residuals as fly ash in concrete and desulfurisation gypsum in wallboard. A disposal cost becomes an input sold to another industry.
By-product pricing vs related pricing strategies
How to use it
- Map every output of your process, including data, heat and scrap, and what each costs you today.
- Ask which industries could use each output, and talk to two or three potential buyers.
- Price by-products at least above handling cost, and count avoided disposal costs as part of the gain.
- If usage data improves your product, decide openly whether and how users share in that value.
- Check regulation first: data, waste and food by-products each come with their own rules.
In AI, the interaction is often worth more than the subscription, because usage produces the traces that improve the next model. The Business Engineer explains why that by-product sits at the centre of post-training economics.

Frequently asked questions
What is by-product pricing?
Setting prices for the secondary outputs of a production process so that they generate revenue instead of disposal costs.
What is an example of by-product pricing?
Fly ash from coal power plants sold for use in concrete, or whey from cheese-making sold as a protein ingredient.
How does by-product pricing help the main product?
The extra income lowers the effective cost of the main product, so the firm can charge less for it or earn a higher margin.
Is data a by-product?
For many digital and AI services, usage data is a by-product that can improve the product; who should benefit from it is debated.

By-product pricing involves setting prices for secondary products generated during manufacturing processes. It aims to recover production costs and generate additional revenue through the sale of by-products. Use cases include manufacturing, agriculture, and energy production. However, challenges include managing market demand fluctuations and addressing environmental impact concerns.
Key Concepts of By-Product Pricing
- Secondary Outputs: By-products are secondary outputs that are not the primary focus of production but still have economic value.
- Waste Reduction: By-product pricing aligns with sustainability goals by reducing waste and maximizing resource utilization.
- Revenue Generation: It allows businesses to generate additional revenue streams from outputs that would otherwise be treated as waste.
By-Product Pricing Strategies
- Cost Allocation: Allocate production costs to both the primary and by-products to determine their respective cost structures accurately.
- Market Assessment: Identify potential markets for the by-products and assess their demand and pricing dynamics.
- Bundling: Consider bundling primary products with related by-products to create value-added offerings for customers.
Real-World Examples of By-Product Pricing
- Meat Processing: In the meat processing industry, by-products like bones, hides, and organs are turned into revenue-generating products such as pet food, leather goods, and pharmaceuticals.
- Sugar Production: In the sugar industry, molasses, a by-product of sugar refining, is often sold to other industries for use in products like animal feed, alcohol, and yeast production.
- Petroleum Refining: Petroleum refineries produce various by-products such as asphalt, lubricants, and chemicals from crude oil processing, creating multiple revenue streams.
Benefits of By-Product Pricing
- Increased Revenue: By-product pricing enables businesses to capture value from secondary outputs, increasing overall revenue.
- Cost Offset: Revenue from by-products can offset production costs, making primary products more cost-competitive.
- Sustainability: By maximizing resource utilization and minimizing waste, by-product pricing aligns with sustainability and environmental goals.
- Risk Mitigation: Diversifying revenue streams through by-products can mitigate risks associated with fluctuating primary product prices.
Challenges and Considerations
- Market Fluctuations: The value of by-products may be subject to market fluctuations, requiring businesses to adapt their pricing strategies accordingly.
- Regulatory Compliance: Some by-products may be subject to specific regulations, affecting their production and pricing.
- Resource Allocation: Deciding how to allocate resources (e.g., labor and equipment) to by-product utilization can be complex.
By-Product Pricing Additional Examples
- Lumber Mill: A lumber mill produces sawdust as a by-product during the process of cutting and shaping wood into lumber. The sawdust can be priced and sold to other industries for use in particleboard, mulch, or animal bedding.
- Sugar Refinery: In sugar refining, molasses is generated as a by-product from the extraction of sugar from sugarcane or sugar beets. The molasses can be priced and sold to be used in the production of alcohol, animal feed, or as an ingredient in certain foods.
- Petroleum Refinery: Refineries producing gasoline also generate by-products such as petroleum coke or asphalt. These by-products can be priced and sold for use in various industrial applications, including energy production and road construction.
- Dairy Farm: In dairy farming, manure is a by-product of milk production. Farmers can utilize manure as fertilizer or even consider pricing it for sale to other agricultural operations.
- Brewery: Breweries produce spent grains as a by-product during the beer brewing process. These spent grains can be priced and sold to farmers for use as animal feed.
- Power Plants: In energy production, power plants often generate heat as a by-product. This heat can be captured and sold to nearby facilities or used for district heating systems.
- Fish Processing Plant: Fish processing plants generate fish waste as a by-product when processing seafood. The waste can be priced and sold for conversion into fishmeal, fish oil, or other products.
- Textile Manufacturing: Textile manufacturers often produce textile waste and trimmings as by-products during the production process. These by-products can be priced and sold for use in insulation, stuffing, or recycling.
- Automotive Industry: The automotive industry generates various metal scraps and leftover materials as by-products during the manufacturing of vehicles. These materials can be priced and sold to metal recycling companies.
- Fruit Juice Processing: Fruit juice processing plants produce fruit peels and pulp as by-products. These can be priced and sold for use in animal feed, composting, or extraction of essential oils.
- Coffee Roastery: Coffee roasters produce coffee chaff, which is the outer husk of the coffee bean. This by-product can be priced and sold for use as mulch, compost, or in specialty products.
- Poultry Farm: Poultry farms generate chicken feathers as a by-product during processing. Feathers can be priced and sold for use in various applications, including animal feed and fertilizer.
