2. Introduction to main business or products during the reporting period

The company is a high-tech enterprise focusing on the comprehensive utilization of waste resources. Adhering to the development concept of "green, recycling, low-carbon and environmental protection", the company aims to realize the full resource utilization and safe disposal of municipal solid waste, actively participates in the construction of "waste free city" in China, is a pioneer in the construction of "waste free city" in China and Toread Holdings Group Co.Ltd(300005) , and strives to become a highly competitive construction and operation service provider of "waste free city".

The company is mainly engaged in the resource utilization of hazardous waste, harmless disposal of hazardous waste and disassembly and treatment of e-waste.

1. Business model of hazardous waste resource utilization

(1) Profit model

The company collects waste mineral oil from auto repair enterprises and manufacturing enterprises for resource utilization, produces lubricating oil base oil and other products, and sells them to downstream renewable resource utilization enterprises to make profits.

(2) Procurement mode

The marketing department of the company is responsible for the development and maintenance of waste production units such as automobile repair enterprises and manufacturing enterprises, sign the procurement framework agreement after reaching the cooperation intention with waste production units, agree on the quantity, transportation mode and utilization and disposal mode of waste mineral oil planned to be used and disposed, and determine the procurement price according to the quality grade of waste mineral oil, market competition and other factors.

After receiving the demand for disposal of waste mineral oil entrusted by the waste production unit, the company will be collected by the hazardous waste collection and transportation team on-site, and the transportation expenses will be mainly borne by the company. After the waste mineral oil is transported to the plant, the company is responsible for checking the source and weight of the waste mineral oil, and warehousing after quality inspection. In the process of waste mineral oil transfer, the company strictly implements the hazardous waste transfer receipt system, and timely enters the receipt information into the government solid waste management information platform to ensure the traceability of the whole process of hazardous waste transfer. The company's hazardous waste transport vehicles are equipped with road transport vehicle satellite positioning devices and intelligent video monitoring and alarm devices, and carry out the whole process tracking and data summary through the "Xiaomage" cloud data platform.

(3) Production mode

The disposal and Utilization Department of the company shall reasonably arrange the processing and utilization of waste mineral oil according to the quantity and quality grade of waste mineral oil collected. The waste mineral oil is classified into different oil pools according to its quality. After a series of treatment processes such as sedimentation and impurity removal, heating and layered water removal, the lubricating oil base oil is generated. The solid waste generated in the process of resource utilization shall be entrusted to units with corresponding qualifications for disposal.

The company has formulated a strict business record and reporting system to record the reception, utilization and disposal of hazardous waste, the operation status of production facilities, facility maintenance and environmental monitoring data, monitor and manage the whole production process, and regularly report the business activities of hazardous waste to the competent ecological and environmental department.

(4) Sales model

The lubricating oil base oil produced by the company is the basic raw material for manufacturing lubricating oil. After the downstream renewable resource utilization enterprise purchases the lubricating oil base oil from the company, it can be made into different categories of lubricating oil through multiple processes such as distillation, purification, refining and blending. The Sales Department of the company is responsible for the development and maintenance of downstream customers. After reaching the cooperation intention, the sales framework agreement is signed to agree on the product quantity, transportation mode and settlement mode. The price of lube base oil fluctuates greatly affected by the price of crude oil, so the sales price is not agreed in the framework agreement. When the customer places an order, the sales price is determined by comprehensively considering the price of crude oil, market supply and demand and other factors.

The raw materials of lubricating oil base oil produced by the company are waste resources, with relatively low production cost, high product cost performance and strong market demand. The company generally adopts the settlement method of payment before delivery. After the customer pays the full payment for the goods, it will organize logistics to pick up the goods on site, and the freight will be borne by the customer.

2. Business model of harmless disposal of hazardous wastes

(1) Profit model

The company collects hazardous wastes with low recycling value such as waste emulsion, waste filter element and waste oil barrel from automobile repair enterprises and manufacturing enterprises for harmless disposal, and makes profits by charging disposal service fees from waste production units.

In addition, in the process of harmless disposal, recycled resource products such as waste steel are recycled and sold to downstream renewable resource utilization enterprises to realize income.

(2) Collection mode

The company conducts harmless disposal of hazardous wastes, mainly including waste emulsion, waste oil drum, waste filter element, etc., whose source is similar to that of waste mineral oil, mainly including automobile repair enterprises and manufacturing enterprises. After the company receives the demand for disposal of hazardous waste entrusted by the waste producing unit, the hazardous waste collection and transportation team will collect it on site and transport it back to the company for disposal. The transportation cost is mainly borne by the company, and the collection process is basically the same as that of waste mineral oil. The difference is that the recycling value of these hazardous wastes is low. When collecting, the company collects the disposal service fee from the waste producing unit.

(3) Service mode

The marketing department of the company is responsible for the development and maintenance of customers such as auto repair enterprises and manufacturing enterprises. Generally, the company signs a hazardous waste disposal service agreement after reaching the cooperation intention with the customer, comprehensively considers the type, disposal cost, distance and other factors of the hazardous waste to determine the unit price of the disposal service, and settles with the waste producing unit according to the actual disposal weight; For some customers with small waste production, the company signs environmental protection technical service agreements with them, charges fixed service fees according to the service period, and provides them with a package of services such as hazardous waste disposal, assistance in transfer form declaration and so on within the agreed period.

After the hazardous waste collection and transportation team transports the hazardous waste to the plant and weighs it, the disposal and utilization department adopts customized processes for harmless disposal of different types of hazardous waste. For example, the waste emulsion needs to go through multiple processes such as air flotation, biochemical treatment, physicochemical treatment and so on. The wastewater and waste gas generated during the disposal process will be discharged after meeting the discharge standards. The solid wastes such as oily waste residue, water treatment sludge and oily waste paper will be entrusted to units with corresponding qualifications for disposal to ensure that all wastes are safely and properly disposed of. 3. Business model of e-waste dismantling and treatment

(1) Profit model

The company sells the dismantling products obtained from the dismantling of electronic waste to downstream renewable resource utilization enterprises, and applies for the fund subsidy for the disposal of waste electrical and electronic products according to the standard dismantling type, quantity and fund subsidy standard of waste electrical and electronic products, so as to make a profit.

(2) Procurement mode

The electronic wastes purchased by the company, such as waste TV sets, waste refrigerators and waste air conditioners, were initially generated in thousands of households, enterprises and institutions. In contrast to the logistics mode of home appliance sales from centralized to decentralized, the front end of the e-waste recycling chain is extremely scattered, and the recycling process from decentralized to centralized presents a reverse logistics mode. Mobile recyclers collect electronic waste from thousands of households through the streets and lanes, and then collect it to the local waste material recycling station (individual recycler). After being collected and classified by the recycling station, they are directly sold to waste electrical and electronic products processing enterprises for disassembly and treatment, or after being sold to waste material recycling enterprises, they are sold by waste material recycling enterprises to waste electrical and electronic products processing enterprises.

The company is one of the only five designated disposal enterprises of waste electrical and electronic products in Zhejiang Province. It occupies a relatively dominant position in the chain of e-waste recycling and treatment, and the upstream supply is sufficient. In order to improve the efficiency of e-waste procurement, the company adopts the mode of centralized recycling to purchase e-waste. The specific business process is as follows:

① The marketing department is responsible for the development and maintenance of waste material recycling enterprises and individual recyclers, sign the procurement framework agreement after reaching the cooperation intention with suppliers, and agree on the price determination mode, transportation mode and settlement mode of e-waste;

② The marketing department shall formulate the annual procurement plan and monthly procurement plan according to the disassembly plan formulated by the production department;

③ The marketing department determines the purchase price according to the market situation, and issues the purchase demand to waste material recycling enterprises and individual recyclers through wechat, telephone and other channels;

④ The supplier delivers the goods to the door, registers and lines up for unloading at the company, and the receiving point is equipped with Weighbridge and video monitoring equipment. The company checks and checks the e-waste after weighing, generates a barcode containing the information of the deliverer, warehousing time, type and quantity of goods, and enters it into the data management information system networked with the Ministry of ecology and environment, so as to facilitate the traceability of information and the supervision of government departments.

(3) Production mode

The company is equipped with a special disassembly line for "four machines and one brain". The production department formulates the disassembly plan every day to clarify the type, quantity, production line arrangement, operation team and other matters of the dismantling and disposal of waste electrical and electronic products. The electronic waste is classified and disassembled through the combination of labor and machinery to obtain waste metal, waste plastic, waste compressor and other renewable resource products, All disassembly products produced on the same day shall be warehoused on the same day. In the process of dismantling and treating electronic waste, the company separates hazardous waste such as waste circuit board, lead containing glass, phosphor and mercury containing backlight tube, which is collected by the company and entrusted to business units with corresponding qualifications for disposal.

According to the requirements of the guide for dismantling and production management of waste electrical and electronic products, the company has formulated detailed dismantling and disposal operation specifications and strict production management system. The company has set up on-site video monitoring system at key points such as the import and export of the plant, cargo loading and unloading area, loading port, feeding port, disassembly and treatment station of key products and storage area to monitor the whole process from the arrival of waste electrical and electronic products to the delivery of disassembled products, track and record the whole process of disassembly and treatment of waste electrical and electronic products, and form corresponding basic record form (production log), Summarize and form a report on a daily basis and submit it to the competent department of ecological environment in a timely manner. After the dismantling operation is completed, the company shall conduct self inspection in accordance with the requirements of the work guide for the review of the dismantling and disposal of waste electrical and electronic products, and regularly submit the dismantling and disposal form to the competent department of ecological environment for review.

(4) Sales model

Dismantling products such as waste metal, waste plastic and waste circuit board are important renewable resources. After purchasing from the company, downstream renewable resource utilization enterprises can generate industrial raw materials such as metal and plastic through deep processing to extract rare and precious metals such as gold and silver. The Sales Department of the company is responsible for the development and maintenance of downstream customers. After reaching the cooperation intention, the sales framework agreement is signed to agree on the goods category, transportation mode and settlement mode. The price of disassembled products fluctuates greatly affected by the price of bulk commodities such as metals and plastics, so the sales price is not agreed in the framework agreement. When the customer places an order, the sales price is determined by comprehensively considering the price of relevant bulk commodities, market supply and demand and other factors.

After recycling, the company's disassembled products can be used as good industrial raw materials, and their raw materials are electronic waste. Relatively speaking, they have high cost performance and strong demand in the downstream market. When selecting customers, the company usually selects customers with higher quotation for cooperation, and usually adopts the settlement method of payment before delivery. After paying the full payment, the customer will organize logistics to pick up the goods on site, and the freight will be borne by the customer. 3.
