Difference Between By Product and Waste

Key Difference – By Product vs Waste

By product and waste are two components that should be managed effectively in order tocontrol costs. The key difference between by product and waste is thatby product isa secondary product obtained incidentally in the manufacturing process of the main product whereas waste is defined asinefficient activities that do not add value to a product or service.Understanding these concepts is essential to implement necessary strategies to manage by-products and waste.

What is a By Product?

By-product is a secondary product obtained incidentally in the manufacturing process of the main product. By-products contain some saleable value, which is generally much less than the value of the main product. Many by-products often require further processing before sale.

E.g. In the dairy industry, buttermilk (by product) is produced along with butter and cheese (main products).

Companies can use a number of methods to account for by-products as follows.

Miscellaneous Income Method

Miscellaneous income method is used when the by-product has very limited commercial value and low importance. Thus, the sales value of the by product is recorded as other income or miscellaneous income in the profit and loss account under this method.

Total Sales Less Total Cost

Under this method, the sales value of the by-product is added to the sales value of the main product. As a result, the sales revenue will include the proceeds from both main product and by-product. The main disadvantage of this method is that the revenue from the main product and the by-product cannot be identified separately.

Standard Cost Method

Standard cost method can only be used if the company is operating with astandard costing system. In standard costing, a pre-determined cost is assigned to a product based on the technical assessment. Here, the by-product is valued at the standard rate, which remains constant for a predetermined time period.

What is Waste?

In a commercial and industrial sense, waste is defined as inefficient activities that do not add value to a product or service. In other words, waste is anything that does not generate any economic value to the company. Waste is found in both production and service oriented organizations. Below are some common ways that companies encounter waste.

Unwanted Material Left from Production Process

This is encountered when excess raw materials are ordered or the ordered materials do not meet the expected quality standard and cannot be used for production. Companies should be careful about how much raw materials are ordered in expected quality.

Product Defects

A product defect is a unit of output which has no marketable value. It is important to maintain defects at a minimum level and companies have a defined acceptable rate of maximum defects for a specified period.

Over Production

This occurs as a result of incorrect demand estimations and excess products are manufactured before it is needed.

Idle Capacity

This is the amount of capacity not used for production. Generally, it is very difficult for a business to operate at maximum capacity due to bottlenecks, which are various limitations in the production process.

Idle Labor

Idle labor occurs when workers are paid for the time that they are not involved in the production. If the labor idle time is high, this results in increased loss of profits.

Waste disposal and waste management have become aspects that companies must spend adequate resources and time since the rules and regulations are continuously increasing, especially in industries where chemical and other hazardous waste is originated as a result of the production process.

What is the difference between By Product and Waste?

By Product vs Waste
By product is a secondary product obtained incidentally in the manufacturing process of the main product.	Waste is defined as inefficient activities that do not add value to a product or service.
Type of Organization
By-products are encountered in production-oriented organizations	Waste is encountered in production and service oriented organizations
Commercial Value
By-products have limited commercial value.	Waste has no commercial value.

Summary- By Product vs Waste

The difference between by product and waste mainly depends on the existence of a commercial value. By-product has a commercial value, even though it is limited; thus, it can be sold to make a revenue. Waste can be identified as any aspect that reduces the economic efficiency and does not result in a productive output. If waste is managed effectively, companies are able to enjoy significant advantages in the form of cost savings.
