The recycle economy is the first stage of knowledge economy. In March 2005, the author attended the forum of 'Festival of Thinkers' in the capital of United Arab Emirates, Abu Dhabi. Through five day' discussing with 10 Nobel Prize winners and 18 thinkers from five continents, the conception of Recycle Economy is regulated. The former principle of '3R' in clean production has been expanded to '5R' in new recycle economy, adding concept of 'rethink' and 'repair' to the 'reduce, reuse and recycle' This article makes a full exposition to the origin, contents and its innovation to the classical western economics of the new recycle economics. Before the 2008 Beijing Olympics, the article discusses the application of new recycle economy in terms of promoting the ability of national innovation system and independent innovation, city construction and the industry innovation concerning Beijing's features.

The materialism prevalent in the modern industrial society and concern for the destruction of nature have led people to long for the returning to nature and excite their nostalgia for old. These phenomena induced in modern fashion naturalism retrospectivism ethnicism and primitivism. In the following we present our findings in regard the roles and relationships of the tie dying with the modern fashion design. in regard the roles and relationships of the tie dying with the modern fashion design. The common basic themes are founded as follows; 1. Naturalism: The tie dying is from very old times and has evolved in many parts of the world producing their own natural designs and color. They bear the characteristic of nature; the pleasantness smoothness and complexity. 2. Individualism and hand made: No two items produced by the tie dying technique are identical even though they are similar by design and their individuality is to some extent determined by chance. The retrospetivism and individualism are themes relating to the modern fashion. 3. Ethnicism and primitivism: The tie dying brings up the 'ethnic and traditional' to us and their designs and colors present the new images of the ethnic and primitive influences to the modern designs. 4. Ecology recyle and grunge look: The tie dying represent the recycle of the used natural resources such as making the old cloths useful again in new forms by tie dying them. The old clothes thus restored show wrinkled untidy and somewhat loosely fit form. This image of 'grunge look' is one of the central theme of the modern fashion.

As sewer flooding frequents due to localized and concentrated stormwater and increased non-permeable surface area after urbanization, building cities with sound water recycle and accordingly efficient management of rainwater is demanded. To do this, the existing sewage (including rainwater) fee imposition system should be philosophically evaluated. This study presents problematic issues of the existing domestic sewage fee imposition system considering the principle of sharing costs on the service of sewage and rainwater collection and treatment. Four methods to improve the existing sewage fee imposition system are suggested: 1) imposing stormwater fee according to Polluter Pays Principle, 2) clarification of the share of public sector, 3) reducing or exempting the sewerage fee for inhabitants reducing urban runoff by constructing their own rainwater management facilities, 4) imposing charge for discharging rainwater to sewers due to new development action. Short, mid, or long term planning for rainwater management is recommended considering the situation of each municipality.

Indonesian Ministry of Environment estimates that each year 170 cities and regencies in Indonesia produce 45,764,354.30 $m^3$ or approximately 11,441,091.08 ton of solid waste. Unfortunately, unsustainable management system has created a severe waste problem, hazardous to health and environment. This paper deals with the problem and offers some solutions. They are 3R (Reduce Reuse and Recycle), waste-to-energy concept and landfill gas (LFG) utilization. While 3R policy has been adopted by the government, the remaining two technologies are still dormant. Thus the paper provides a complete yet compact analysis of technology, economics, and environment aspect of waste-to-energy and LFG. Given the facts of waste production and management in Indonesia, the purpose is to encourage Government of Indonesia and other stake holders (including international community) to explore and exploit this potential. Potential of reducing waste negative externality while receiving extra revenue. Two bird with a stone.

Re-manufacturing is the process of recovering the function and performance of the original product through a re-assembly process such as a new product assembly process after reprocessing by recovering used products or parts that are in the disposal stage at the end of their lifespan. One of the manufacturing methods. The remanufacturing industry is important not only in terms of environmental protection, but also in terms of economics. The success or failure of the industry as a whole depends on trust in products and price competitiveness. Image processing systems are used to reduce labor costs and improve product reliability in the product manufacturing process. In this study, foreign substances and defects that are difficult to identify with the human eye are detected by using the pre-processing step of determining whether to recycle the drum and image processing immediately before shipment after regenerating the drum to regenerate the waste drum.
