Im­proved San­i­ta­tion in Beijing

The Beijing En­vi­ron­men­tal San­i­ta­tion En­gi­neer­ing Group Lim­ited has transformed it­self into a com­pre­hen­sive, ur­ban and ru­ral en­vi­ron­men­tal ser­vices provider.

Beijing (English) - - CONTENTS -

De­cem­ber 21, 2017 was an im­por­tant day for the Beijing En­vi­ron­men­tal San­i­ta­tion En­gi­neer­ing Group Lim­ited (BESG). That very same day, the year be­fore, Gen­eral Sec­re­tary of the CPC Cen­tral Com­mit­tee Xi Jin­ping made an im­por­tant an­nounce­ment at the 14th meet­ing of the Cen­tral Lead­ing Group on Fi­nan­cial and Eco­nomic Af­fairs on how the garbage clas­si­fi­ca­tion sys­tem needed to be ap­plied na­tion­wide. This was the first time for a head of state and head of the Party to give in­struc­tions on han­dling garbage. Xi had no­ticed peo­ple’s con­cerns and fully ap­plied a peo­ple-cen­tred phi­los­o­phy, a shot in the arm for BESG on its in­no­va­tion-driven, qual­ity de­vel­op­ment track.

The com­pany has been guided by the Cen­tral Gov­ern­ment con­cepts, es­pe­cially com­bin­ing green with eco­log­i­cal de­vel­op­ment, and has broad­ened its man­age­ment phi­los­o­phy, ex­pe­ri­ence and tech­nol­ogy, ap­ply­ing them in more than 40 cities. Progress has been made in its equip­ment in­no­va­tion as well as in new, tech­no­log­i­cal, spe­cific so­lu­tions to garbage dis­posal.

That means that BESG has transformed it­self into a com­pre­hen­sive, ur­ban and ru­ral en­vi­ron­men­tal ser­vices provider. In do­ing this, it has linked con­sul­ta­tion, plan­ning, de­sign, con­struc­tion and ser­vices with a sin­gle, one-stop ur­ban en­vi­ron­ment provider.

Ac­cord­ingly, on De­cem­ber 21, 2017, BESG pub­lished its an­nual sci­en­tific and tech­no­log­i­cal re­port and an­nounced its “Three So­lu­tions” ap­proach to ur­ban garbage sort­ing, ru­ral en­vi­ron­men­tal san­i­ta­tion, and ur­ban lanes. Mean­while, it an­nounced that it will work with the China Gezhouba (Group) Co., Ltd. (CGGC) in build­ing a dis­posal and util­i­sa­tion plat­form for solid waste. As the Chi­nese New Year ap­proaches, BESG is pool­ing its many re­sources to set off on a new jour­ney.

Seven ‘Black Tech­nolo­gies’

“Our new strat­egy fea­tures in­no­va­tion- driven de­vel­op­ment. Be­cause san­i­ta­tion re­quires man­power and equip­ment, im­prove­ments and break­throughs in equip­ment are a com­mon con­cern and ma­jor ob­jec­tive of the in­dus­try,” is how the ViceGen­eral Man­ager and spokesman of BESG, Luo Wei, de­scribed how to form a world- class com­pre­hen­sive ser­vice provider in the en­vi­ron­ment field. BESG has im­ple­mented an in­no­va­tion­driven de­vel­op­ment strat­egy with the lat­est sci­en­tific and tech­no­log­i­cal ad­vances in san­i­ta­tion.

Dis­posal Tech­niques and Kitchen Garbage Equip­ment

Af­ter five years of R& D, BESG’S ad­vanced equip­ment now in­cludes a high- pres­sure press sep­a­ra­tor that can break down and sep­a­rate house­hold garbage and kitchen garbage in an adapt­able way, with greater ef­fi­ciency, and lit­tle loss of biomass. BESG has also de­vel­oped a type of shaker that can sep­a­rate bro­ken glass, bro­ken ce­ram­ics, shells, bot­tle caps, and stain­less steel ef­fi­ciently and turn the biomass of kitchen garbage into pulp.

Ul­tra-high-tem­per­a­ture Fer­men­ta­tion

BESG’S ul­tra-high-tem­per­a­ture aer­o­bic fer­men­ta­tion tech­nol­ogy treats or­ganic solid waste with the help of micro­organ­isms and can dis­pose of sludge, live­stock and poul­try waste, kitchen garbage and other or­ganic waste. Th­ese waste prod­ucts de­com­pose un­der ul­tra-high-tem­per­a­ture and the fer­mented prod­ucts can be used as or­ganic fer­tiliser.

Sus­tain­able Land­fill

In keep­ing with its sus­tain­able de­vel­op­ment phi­los­o­phy, BESG has de­vel­oped a land­fill tech­nique with biore­ac­tor ac­cel­er­ated sta­bil­i­sa­tion at the core, and sifts sta­bilised waste, pro­duc­ing nu­tri­ent soil, roadbed ma­te­ri­als, and other prod­ucts. Emp­tied land­fill ar­eas can be filled with new waste.

Bio­gas Pu­rifi­ca­tion

To ad­dress the dif­fi­cul­ties as­so­ci­ated with the tra­di­tional bio­gas pu­rifi­ca­tion process, BESG has de­vel­oped mov­able bio­gas sep­a­ra­tion and pu­rifi­ca­tion equip­ment with a six- step fil­tra­tion process and can re­move harm­ful mi­cro- con­stituents in meth­ane gas so that meth­ane con­cen­tra­tions can reach 99 per­cent af­ter pu­rifi­ca­tion.

Flammable Ice out of Land­fill Gas

In its sci­en­tific in­no­va­tion, BESG has fo­cused on heat and mass trans­fer in a mul­ti­phase re­ac­tion sys­tem and has come up with flammable ice tech­nol­ogy, whereby land­fill gas (marsh gas) meets wa­ter, pro­duc­ing flammable ice with a cer­tain amount of gas con­cen­tra­tion and dif­fer­ent struc­ture.

Leachate Mobile Treat­ment Plant

BESG uses bi­ol­ogy, chem­istry, physics, and pho­to­syn­the­sis to turn liq­uids from degra­da­tion-re­sis­tant, black, stinky garbage into colour­less, odour­less re­claimed wa­ter for ur­ban dusty and green spa­ces.

Plasma Gasi­fy­ing Tech­nol­ogy

This is a new al­ter­na­tive for in­cin­er­a­tion tech­nol­ogy that BESG de­vel­oped so that house­hold garbage can be turned into com­bustible gas for pro­duc­ing electric and heat en­ergy with no pol­lut­ing gas, in­clud­ing dioxin, pro­duced.

Three So­lu­tions for Ur­ban Is­sues

In ac­cor­dance with Xi Jin­ping’s de­ci­sions on the garbage clas­si­fi­ca­tion sys­tem of De­cem­ber 21, 2016, BESG has worked out a way to han­dle ur­ban garbage sort­ing, im­prov­ing ru­ral en­vi­ron­men­tal san­i­ta­tion, ur­ban lanes, the en­vi­ron­ment, and san­i­ta­tion in both ur­ban and ru­ral ar­eas.

Ur­ban Garbage Sort­ing Plan

Garbage sort­ing is not just a mat­ter of how we dis­card the garbage, but an en­tire process of dis­card­ing, col­lect­ing, trans­port­ing, and dis­pos­ing that are in­ter­linked. With­out a sys­tem, th­ese seg­ments can’t go far. BESG has worked out a sys­tem­atic, smart- sort­ing so­lu­tion for garbage that has been ap­plied in 1,000 neigh­bor­hoods and by over 100 or­gan­i­sa­tions, and has ben­e­fit­ted nearly 500,000 peo­ple. This “e- re­source” sys­tem has be­come a leader in the garbage- sort­ing plat­form in­dus­try. BESG’S Garbage Sort­ing Stan­dards and Tech­no­log­i­cal Norms re­spon­si­bly teaches how to put solid waste of dif­fer­ent types into designated con­tain­ers or stor­age ar­eas.

Solv­ing Ru­ral En­vi­ron­men­tal and San­i­ta­tion Prob­lems

Ru­ral ar­eas have poor garbage col­lect­ing, trans­port­ing and dis­posal sys­tems, re­sult­ing in fre­quent prob­lems. The cur­rent modes re­sult in in­suf­fi­cient funds for ru­ral garbage treat­ment, and se­verely limit ru­ral garbage sort­ing de­vel­op­ment. BESG’S over­all so­lu­tion for this is to de­velop man­age­ment of solid waste through a com­pre­hen­sive sys­tem of sort­ing, col­lect­ing, and trans­porta­tion.

Ur­ban Lane En­vi­ron­men­tal and San­i­ta­tion Work Norms

The treat­ment of ur­ban lanes is an im­por­tant sign of the over­all ur­ban en­vi­ron­men­tal con­di­tion. When we con­sider that ur­ban lanes are of­ten “cramped, dis­or­derly, and scat­tered about,” com­bined with the cli­mate prob­lems of Beijing, the com­pany has done tri­als for more than a year to come up with a re­gional, sea­son- and peo­ple-based model and im­proved equip­ment for clean­ing them up. It re­sulted in a pro­por­tion of small, al­l­elec­tric san­i­ta­tion ve­hi­cle work­ing ar­eas of no less than 50 per­cent of BESG’S to­tal work­ing area.

Co­op­er­at­ing with Gezhouba for a Liv­able City

CGGC and BESG en­tered into a cooperation agree­ment on De­cem­ber 20, 2017, to build a dis­posal and util­i­sa­tion plat­form to­gether, and to set up the Gezhouba-besg Co. us­ing BESG tech­nol­ogy for sort­ing solid waste, such as pa­per, rub­ber, fab­rics, and plas­tic, and harm­ful waste. Luo Wei ex­plains that Beijing’s en­vi­ron­men­tal san­i­ta­tion should meet the stan­dards for turn­ing it into a world- class har­mo­nious and liv­able cap­i­tal and the san­i­ta­tion sec­tor should im­prove the en­vi­ron­ment and ecol­ogy, deal with pol­lu­tion ef­fec­tively, en­sure the cyclic util­i­sa­tion of re­sources, and em­ploy low- car­bon de­vel­op­ment. It also needs to find bet­ter ways to meet peo­ple’s needs in the ar­eas of con­ve­nience, liv­abil­ity, di­ver­sity, and fair­ness. In this, BESG’S in­no­va­tions will be fur­ther ap­plied and up­graded in man­age­ment and prac­tice.
