Environmental Protection

The natural environment is fundamental for the survival of humans and animals. At present, our natural environment is facing various threats, including energy shortage, depletion of natural resources, environmental pollution, global climate change etc. We continue to take various innovative and effective measures to reduce the negative impacts on the environment during the entire production process and make efforts to protect the homes of humans and animals.

Ecological conservation

WH Group respects the natural environment, which we all rely on to survive. We hope that through our own efforts, we will minimize damage to the environment and maintain Earth’s stability and sustainability. Our priority is the rational and healthy utilization of ecological resources to ensure that our production and operation are carried out within the environmental capacity and ultimately reduce the impact on the surrounding ecological environment. Over the years, the efficiency of rearing hogs has improved, which not only generates economic benefits, but also reduces emissions from manure and the Group’s demand for agricultural land.

Reducing carbon emissions

Climate change is undoubtedly one of the most important challenges faced by the planet today. Our business inevitably emits greenhouse gases, but we are working hard to continuously improve energy efficiency to reduce greenhouse gas emissions per unit of production capacity.

The majority of WH Group’s direct greenhouse gas emissions (Scope 1) are from our vehicle fleet and the use of fossil fuels in our plants. Our indirect greenhouse gas emissions (Scope 2) come from the use of purchased electricity and steam. Accordingly, we have enhanced the overall carbon reduction benefits in three aspects:

  • Improved the machinery to enhance energy efficiency
  • Promoted the use of renewable energy
  • Optimized distribution and transportation routes to improve efficiency

  • Reduced packaging for new product line

    In 2017, Smithfield launched new Prime Fresh Deli pre-packed lunchmeats. This unique and extremely simplified packaging design seems like a slice at the deli counter, which keeps the meat fresher. Moreover, this type of packaging uses 31% less packaging materials than traditional delicatessens, thereby improving transportation efficiency and reducing waste.

  • Biogas slurry is returned to the field to promote circular economy

    On farms in China, we have built waste water treatment plants to treat manure. After it is treated in the waste water treatment plant, the manure is transported through a biogas slurry assimilation pipeline to plantations in surrounding areas for fertilizing the fields. We have laid 50 kilometers of pipelines in total, covering more than 1,600 hectares of land.

  • Shuanghui builds sustainable demonstration zone and a modern eco-agriculture areas

    We support and guide farmers and start-ups in actively applying organic fertilizer, developing and building plantations, and using manure from farm to grow fruits and vegetables. At present, some plantations that utilize manure as fertilizer have been designated as eco-agriculture demonstration areas by local authorities.
