*3.2. Standard Package*

The standard package is based on introducing some circular economic projects, namely the company's more advanced industrial symbiosis. As mentioned above, the company should return by-products generated by the production process to local farmers. Still, the company is expected to accumulate more shavings and sell them to particle collectors to produce other goods. Implementing such a project requires additional expenses related to the accumulation of saws, but the proceeds from their sale are expected to cover the maintenance costs. The authors contacted several shavings purchasing companies such as Reinpaul OU, Tikala ID, Ltd. Vegranti and Ltd. SK Green Energies. They concluded that the average purchase price of shavings is 6 EUR/m3. The minimum number of shavings acquired by these companies is 500 m3. Thus, the company will require additional premises for storing 100 m<sup>2</sup> of shavings (Formula (1)), given that the ceiling of the production building is5m[30].

$$\text{S} = \frac{\text{V}}{\text{h}} = \frac{500}{5} = 100 \,\text{m}^2 \tag{1}$$

where: S—required area of the room (m2); V—the volume of shavings/the volume of required storage premises (m3); h—building ceiling height (m).

The company owns the production building. During the interview, the authors has found out that the company pays approximately 1.20 EUR/m2 for heating the production building within the season (which does not include overhead expenses such as management, repair, etc.). Therefore, the cost of maintaining this building will be around 120 EUR per month. However, it should be noted that this building requires heating throughout the year in order to ensure the appropriate maintenance conditions (humidity, air temperature, etc.).

According to this package, the company is not expected to move to another building because it owns the current office building. As mentioned above, the company carried out marketing campaigns: Replace old things with new ones. However, this standard package provides that Furniture Factory customers return the worn-out chair to the company rather than throw it away. Like the suspicious package, the standard package implies that the company will shift from three cars to one car and one electric vehicle.
