Huanyu Renewable Resources International Investment Group mainly invests in four major environmental fields
（1） Space environmental protection
The outer space of the earth has caused great pollution and danger to the earth's space environment due to the detention of man-made satellites and the floating of fragments launched. It is the common requirement of mankind to eliminate the earth's space pollution and restore the earth's clean space.

（2） Air purification field
In modern society, industrialization and other factors cause serious pollution to the earth's atmosphere. The haze and haze are mainly composed of haze, haze and dust, which are mainly composed of heavy metals, such as sulfur dioxide and dust. With the deterioration of air quality, haze phenomenon is increasing and the harm is aggravating.

（3） Land environmental protection
With the highly developed human science and technology, the acceleration of the frequency of product upgrading, the global huge amount of circular economy industry solid waste, put in front of us. Environmental pollution events and a wave of global virus pandemic all predict the seriousness of the earth's pollution.
（4） Marine environmental protection
Marine pollution is becoming more and more serious, and its root causes are as follows:
(1) Coastal industrial enterprises discharge pollutants directly to the sea
(2) The area flowing into the ocean river discharges into the water body
(3) Acid rain in the sea caused by air pollution
(4) Pollution discharge from petroleum enterprises and tourism industry
(5) Overfishing and destroying marine ecological balance
美国环宇再生资源国际投资集团主要投资涉及四大重要环境领域：
(一）太空环保领域
地球外太空由于人类＂人造卫星＂的滞留和发射残片的游浮、给地球的太空环境造成了极大污染和险境。消除地球太空污染、还原地球洁净太空是人类共同的要求。
(二）空气净化领域
现代社会由于工业化等因素给地球大气造成严重的污染。它主要表现在雾霾形态；雾与云都是空气中水汽凝结的产物，霾主要成分是灰尘、二氧化硫、重金属、多环芳烃、微生物等、霾的厚度可达1-3公里。随着空气质量的恶化、阴霾现象岀现增多、危害加重。
(三）陆地环保领域
随着人类科技高度发达、产品更新换代频率的加快、全球巨量的循环经济产业固废、摆到了我们面前。一次次环境污染事件、一波波病毒全球大流行、均预市着地球污染的严重性。
(四）海洋环保领域
海洋污染日趋严重、究其根源有以下五点：
(1）沿海工业企业直接向海洋排污
(2）流入海洋河流区域向水体排污
(3）大气受污染形成酸雨降雨海中
(4）石油企业及旅游产业对海洋排污
(5）过度捕捞、破坏海洋生态平衡
